This study examined the nutrient mass balances of nitrogen and phosphorus in an integrated shrimp (Litopenaeus vannamei) and tomato (Lycopersicon esculentum Mill) culture system using low salinity groundwater in Sonora, Mexico. Most of the nitrogen (43.6%) and phosphorus (98.8%) inputs came from shrimp feed. Approximately 15.2% of nitrogen and 8.9% of phosphorus inputs were converted to harvested shrimp, while 4.1% of nitrogen and 24.6% of phosphorus remained in organic sludge. Environmental losses of nitrogen and phosphorus per ton of product harvested were relatively low at 57 kg of nitrogen and 7.1 kg of phosphorus
The document discusses the creation of the National Nutrient Uptake and Outcome Network (NUOnet) to collect and share nutrient management data. NUOnet was developed using the framework of the existing GRACEnet database. A prototype data entry template was created with additional tabs to collect various types of nutrient data. The goal of NUOnet is to provide a centralized database that connects nutrient, soil, and crop data to help address challenges in nutrient management. It aims to connect to other USDA databases to provide a more comprehensive view of the relationships between agricultural practices, soil health, and environmental and human outcomes.

It discusses the history and environmental characteristics of the Delta region, which includes temperate wetlands along the Paraná River. Silvopastoral systems that integrate tree plantations of species like poplar and willow with cattle raising have increased in the last 15 years. The document describes management techniques for these systems, including using wider spacing for tree planting to allow for a productive understory of grasses and establishment of cattle earlier without damage to trees. The goal is sustainable production of wood, forage, and beef through optimizing the balance between components of the silvopastoral system.
Effect of regulated deficit irrigation on growth and yield of sorghumAlexander Decker
This document summarizes a study on the effects of regulated deficit irrigation on the growth and yield of sorghum. The study consisted of different irrigation regimes (100%, 75%, 50%, 25% of full irrigation) applied to two soil types and measured various growth parameters. The results showed that irrigation regimes of 100% and 75% performed better in terms of growth, water use efficiency, and economic returns compared to 50% and 25% deficit irrigation. Additionally, there were some interaction effects observed between deficit irrigation and soil type. Overall, the study recommends the use of 75% regulated deficit irrigation for optimizing sorghum growth in this agricultural zone.

Phenotypic evaluation of sorghum land-races for early and terminal drought to...ICRISAT
Sahelian zones of West Africa, sorghum is cultivated in areas characterized by harsh environmental conditions – high temperature, low rainfall and low soil fertility. The major goal of sorghum breeding programs is to develop new varieties that maintain, and ultimately increase, crop yields under these abiotic stressors. Despite many efforts and relative progress in sorghum selection, new traits related to drought tolerance are required to accelerate development of more resilient varieties to drought stress. Phenotyping sorghum landraces could lead to identify relevant traits for successful breeding program.

Maximizing Water Productivity of Maize using Alternate Furrow Irrigation at C...Premier Publishers
Nowadays, water availability is a major limiting factor for development of agriculture in arid and semiarid areas. Under conditions of scarce water supply and drought, irrigation practices demand the maximum use of every drop of water to maximize water productivity for irrigated crops. A field experiment with a split-plot design was carried out to evaluate the combined effect of three furrow irrigation techniques and three irrigation levels treatments on maize grain yield and water productivity at Mekhoni Agricultural Research center (MeARC), Raya valley district. Irrigation was applied through furrows in three ways as the main plots: conventional furrow irrigation (CFI), alternate furrow irrigation (AFI), and fixed furrow irrigation (FFI). In CFI, irrigation was applied to every furrow at each irrigation event; in AFI irrigation was applied to alternate furrows which were dry in the preceding irrigation cycle, while in FFI, irrigation was applied to fixed furrows throughout the growing season. Each irrigation technique was further divided into three sub-irrigation treatments: two deficit irrigation levels 75% and 50% ETc and a control of 100% ETc as sub-plot were investigated. Results showed that maximum water productivity was obtained under the AFI system without a trade-off in grain yield and considerably save water. Hence, it is recommended as efficient irrigation technique in areas with limited water resources.
This summary provides an overview of a study conducted by the Rodale Institute from 1992-2001 that compared the effects of compost, manure, and synthetic fertilizer on crop yields, soil quality, and environmental impacts. The study used a maize-vegetable-wheat crop rotation with green manure cover crops. It found that applying compost optimized yields, improved soil quality, and reduced nitrogen runoff compared to other treatments. Compost application resulted in the highest mean maize yields of 7.3 Mg/ha. The study demonstrated that using organic amendments like compost can provide agricultural and environmental benefits over inorganic fertilizers.
Articles about Integrated Roadside Vegetation ManagementScott C. Zager
This document summarizes the Integrated Roadside Vegetation Management (IRVM) approach used in Iowa to manage county roadsides. IRVM integrates the use of native prairie vegetation and appropriate management techniques like prescribed burning and mowing to establish low-maintenance roadsides resistant to weeds and erosion. It began in 1985 in Black Hawk County and has since spread to many other counties in Iowa and surrounding states. The primary goals of IRVM are to establish and maintain native prairie plants in roadsides for wildlife habitat while preventing weeds and soil erosion with minimal inputs.

This document discusses how agricultural production in the U.S. has become highly concentrated in specific regions due to economic and environmental factors over the last century. There is a concern that this concentration makes U.S. agriculture vulnerable to regional droughts. The document explores shifting some production to the Southeast U.S. to diversify risks and reduce impacts on water resources and proposes further modeling work to evaluate economic viability and environmental sustainability of expanded irrigation in the Southeast.
Geoinformatics for runoff diversion planning from the western slope oSainath Aher
- Spatio-temporal variations in water availability are a major attribute of most river basins, especially in semi-arid environments. Many schemes to address water supply and demand gaps have failed due to reduced basin water retention from climate change. Inter-basin water transfers are proposed but implementation faces challenges without proper data.
- In Western Ghats, potential runoff diversion sites have difficult access in rugged terrain, dense vegetation, and human settlements, making data collection inefficient. Geoinformatics using remote sensing and spatial data can help plan runoff diversion more effectively with real-time monitoring and analysis.

Methods and technologies to improve efficiency of water useDamion Lawrence
This document discusses methods and technologies to improve water use efficiency. It notes that competition for freshwater supplies will require maximizing productivity per unit of water consumed rather than land area. Broad systems approaches are needed to optimize irrigation based on factors like water delivery, rainfall, crop needs, soil, and weather. Water can be conserved by reducing evaporation and transpiration and minimizing unusable losses. Agricultural advances will include more efficient irrigation technologies, higher value crops that use less water, and drought-tolerant alternatives. Both agricultural and non-agricultural users will need to cooperate and compromise to adopt more conservative water use approaches.

Comparative analysis between traditional aquaponics and reconstructed aquapon...bijceesjournal
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.
This document summarizes research on managing water for increased resiliency of drained agricultural landscapes. It discusses two issues exacerbated by climate change: nutrient loss from tile drainage causing water quality issues, and lack of water in late summer limiting crop yields, despite excess water in spring. The research aims to address these issues by retaining drained water in the landscape through various methods, including storing water in soils, ditches, fields, buffers, and ponds/reservoirs. Field research is being conducted at several sites to evaluate different water management practices. Modeling and decision support tools are being developed to analyze and apply the results more broadly. The goal is to transform drainage design and implementation to incorporate water retention and recycling.

The 2016 Stream Stewardship team monitored the Berggren Watershed Conservation Area, a riparian restoration site along the McKenzie River. They collected data along 15 transects and found mostly thatch, bare earth, and moss, with roughly equal amounts of planted and invasive species. Their data indicated that the proportion of invasive species has decreased since 2015, showing that restoration efforts are succeeding. Himalayan blackberry was the most prevalent species found, comprising 47% of stems counted, while snowberry and willow species were also common natives. Overall the monitoring showed 14.7% native species ground cover and 10.13% invasive species ground cover across the planted area.
This study evaluated the effects of water hyacinth compost prepared with different starter cultures on the growth and yield of maize. Greenhouse and field experiments were conducted in Kenya from 2011-2012. In the greenhouse experiments, water hyacinth compost was applied to maize plants and various growth parameters were measured over time. Application of water hyacinth compost and diammonium phosphate fertilizer significantly increased plant height, shoot dry weight, root dry weight, and root collar diameter compared to the control. In the field experiments, application of water hyacinth compost and diammonium phosphate increased shoot dry weight at tasseling stage compared to the control. However, yield parameters like 100 seed weight and
This document summarizes several presentations from the 79th Annual Meeting of the Mississippi Academy of Sciences. It describes research on:

Bacteria of tomatoes managed with well water and pond water: Impact of agricu...Agriculture Journal IJOEAR
Abstract— We know that contamination of crops by human pathogens can occur in agricultural settings but we still do not understand precisely which environmental sources represent the highest risks. Human pathogens maybe introduced by wind, worker hygiene, plant mediated factors, insects, water sources, or any combination of these factors. To safeguard against risks to consumers from agricultural waters, FSMA regulations for U.S. crop production require the use of water with an average of less than 126 CFU per 100 ml for applications that come in direct contact with a crop. Due to availability/scarcity however, water from other sources such as agricultural ponds is commonly used. To better understand risks that may be associated with the use of “surface”(often higher microbial load) water sources, we described the bacterial microbiota associated with an agricultural pond, an agricultural well and the corresponding microbiota of tomato carpospheres managed with each water source (also described as phyllosphere). 16S rRNA gene amplicons were used for bacterial profiling of waters and tomato surfaces at four time points over a growing season. Microbial profiles differentiated surface and ground water samples throughout the season, however no significant influence on tomato fruit surfaces could be correlated to either water source. These results suggest that in certain cases, environmental pressures such as wind, dust or other airborne factors may have a more significant impact on the surface microbiology of field crops than irrigation or management water sources do.
Agricultural Weed Research A Critique and Two Proposals.pdfCynthia Velynne
This document provides a critique of agricultural weed research and proposes ways to improve it. The key points are:
1) Agricultural weed research has become too specialized and separated into weed management and weed biology/ecology subdisciplines, despite calls for greater integration.
2) Current research is highly repetitive and descriptive with few novel hypotheses linked to ecological theory.
3) In contrast, invasive plant research explores broader questions grounded in theory and attracts diverse scientists.
4) The authors propose emphasizing interdisciplinary training for weed scientists and focused workshops to develop specific research areas and cross-disciplinary collaboration. This would help push the frontiers of weed science.

Lelah is a new potato variety developed by the University of Wisconsin potato breeding program for chipping. It maintains chip quality for at least a month longer than Snowden after 7-9 months of storage at 45-50°F. Lelah has similar specific gravity to Snowden but in a more consistent manner. While Lelah's field yields are lower than Snowden, it continues to produce high quality chips well beyond when Snowden's yields drop to zero, making it a good choice for chipping late in the storage season.
Nicolet a new long storage variety with high yield potentialFélix Navarro
The document describes the University of Wisconsin potato breeding program and a new potato variety called Nicolet. Nicolet was bred from Snowden and S440 to have longer storage life for chipping while maintaining Snowden's yield and gravity. Test results showed Nicolet had similar or better yield and gravity than Snowden, maintained chip quality longer in storage, and had lower glycoalkaloid levels.
Tundra, a new potato variety with long storageFélix Navarro
Tundra is a new potato variety developed by the University of Wisconsin potato breeding program for long storage and chipping. It maintains chip quality for at least a month longer than Snowden after storage at 45°F due to a later increase in sugars. Tundra usually has a higher specific gravity than Snowden and better tuber shape and uniformity. It also has lower glycoalkaloid content than Snowden. Yield trials found Tundra has medium-high yields similar to Snowden with 91% grade #1 tubers. Tundra has consistent high specific gravity, averaging above 1.080 in multiple trials.

Dandelion Hashtable: beyond billion requests per second on a commodity serverAntonios Katsarakis
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

The Hancock Agricultural Research Station 'Integrating Research and Development for WI Agricultural Systems'
1. The Hancock Agricultural Research Station:
"Integrating Research and Development for WI Agricultural Systems"
By Félix Navarro and Mary Lemere
July, 2013
The Hancock Agricultural Research Station (HARS) is located in Waushara County in the part of
Wisconsin known as the “Central Sands”. Research at HARS began in 1916 by the College of Agricultural
and Life Sciences on land belonging to the Hancock Development Company. In those early years, the
intent of the research was to aid general livestock farmers in their attempt to make a living on the
droughty sands in Central WI. Six years later, the UW- Board of Regents purchased 95 acres from this
private company, and by 1934 they had acquired two more adjacent parcels for a total of 223 acres.
Research efforts for the next twenty years were directed towards dairy feeding, pasture utilization, soil
fertility management, and studies with coniferous and deciduous shelterbelt plantings for wind erosion
control. Irrigation possibilities came to the forefront in the late 1940s with aluminum pipe becoming
available and the discovery of an accessible underground water supply. Irrigation brought renewed hope
to the people of the area and redirected the college's research efforts. Studies began to reveal two-,
three-, and sometimes four-fold increases in crop productivity when irrigation was used. Seventy acres
were added to the station in 1962 to aid in irrigation research, provide low fertility land, and help offset
acreage lost by Hwy 51 relocation and 120 acres were added in 1971 to better serve the research and
outreach functions of HARS.
Hancock Agricultural Research Station headquarters
This station is one of twelve experimental stations administered by the University of Wisconsin-Madison
College of Agricultural and Life Sciences (UW-CALS). The station’s sandy soils and climate are very
suitable to conduct research applicable to the agriculture in central Wisconsin and other similar agro
ecological regions. Research at the Hancock station focuses on irrigated vegetable and field crops with
an emphasis on potatoes, snap beans, cucumbers, field corn, sweet corn and carrots. One of the core
missions of HARS is to support the research and outreach activities of professors, academic staff and
students from different academic departments from UW-CALS. The University of Wisconsin, with the
support of stakeholders, has developed field and laboratory infrastructure necessary to conduct
research at HARS. Of the 412 acres of land, presently more than 300 are tillable. The station has
customized machinery, post-harvest handling and grading sheds, machine and repair shops, office space,
and public events facilities.
1
2. A highlight of the station that attracts a large number of visitors of the general public is the ‘A.R. Albert
& Villetta Hawley-Albert Horticultural Garden’. This horticultural garden located at the east side of the
fields, close to US Interstate 39 is a visible face and main image that thousands of travelers have of the
Hancock station. Presently the garden is maintained with active support and collaboration with master
gardener groups from the region.
The most recent and prominent addition to the station is the Hancock Storage Research Facility (SRF).
The Wisconsin Potato & Vegetable Storage Research Facility was conceived, designed and built by the
potato and vegetable growers of Wisconsin. The potato growers of Wisconsin raised $3.2 million to
build the Wisconsin Potato & Vegetable Storage Research Facility in 2006. The facility contains nine bulk
storage bins and nine lockers for pallet research. Each bulk bin holds 2,000 cwt (200,000 pounds) of
bulk-piled potatoes mimicking commercial storage conditions. Each locker and bin has a separate air
handling and humidity unit to prevent cross-contamination between research projects.

3. The Mission
The Hancock Agricultural Research Station supports research projects, student training and outreach
activities of UW-CALS researchers, notably from the Departments of Horticulture, Plant Pathology,
Entomology, Soil Science, Agronomy and Forest and Wildlife Ecology. UW graduates and researchers like
ourselves we have firsthand knowledge of HARS’ effective role as a training facility for UW-Madison
undergraduate, graduate students, and summer interns. HARS is one of the greatest field laboratories in
the State of Wisconsin where technology is tested before it impacts growers’ fields, industry and the
environment. This facility is expected to play a central role integrating research and development for WI
agricultural systems and beyond.
A measure of Success
Success at the Hancock Ag Research Station can be defined and measured through the quantity and
quality of the research conducted here. A quick survey of recent research contributions to scientific
journals and reports may be a good indicator of the success of research conducted at this station.
Besides contributing to the scientific literature, researchers communicate project results in activities
conducted at the station in events such as separate annual field days on potato, processing crops and
ornamental plants. Similarly research activities are communicated in meetings with stakeholders,
growers and industry committees, other organizations and individual growers. A large number of
undergraduate and graduate students from different departments in CALS receive most of their hands
on experience at HARS. Faculty, staff and students doing research at HARS are part of the body of
scientists that keeps J.C. Walker’s spirit alive ‘with one foot in the furrow’.
Research
University of Wisconsin researchers have conducted at HARS a number of relevant projects that have
contributed significantly to agriculture in WI. These projects include improved soil and crop
management practices, post-harvest and storage management, better disease and pest monitoring and
control as well as new variety options in several crops. Present research projects are pursued to provide
appropriate management tools to growers and industry as well as to reduce impact of agriculture on the
environment. A sample of current projects carried out at the Hancock Ag Research Station is given
below.

7. Ann MacGuidwin is the only plant nematologist at the UW-Plant Pathology Department. Two of her
primary research interests are the role of nematodes in the early dying disease of potato and the
overwinter survival strategies of nematodes. She has demonstrated in field trials that the nematode
Pratylenchus penetrans and Verticillium dahliae interact synergistically to cause potato early dying and is
now studying mechanisms responsible for the interaction. The emphasis of Ann’s program on the
overwinter survival of nematodes is to understand the ecological and physiological parameters which
enable nematodes in Wisconsin to survive freezing. The goal of this collaborative work is to develop
sustainable management strategies for nematode pests of potato, soybean, corn, and other crops
important to the north central region of the U.S
MacGuidwins’ projects at HARS include:
Nematode response to fumigation alternatives in corn, soybeans and potato
Interaction of Verticillim dahliae and Pratylenchus penetrans with greenmanure and solarization

9. Potato Breeding and Variety Evaluation
The goal of the UW Potato Breeding Program in the last few years has been to develop genetically
superior varieties that satisfy or exceed the standard for yield and grade in the fresh and processing
markets. The main objectives of the UW-Potato Breeding Program are as follow:
Development of processing and dual purpose processing and fresh market russet varieties
Development of fresh market russet varieties
Development of long storage chippers as potential ‘Snowden’ replacements
Development of early chippers as potential ‘Atlantic’ replacements
Development of fresh market red skin and specialty varieties
HARS has been of critical importance to the potato breeding program since it provides the opportunity
making selections in a production region where developed varieties are expected to perform well.

Cucumber & Melon Breeding
Yiqun Weng is responsible for cucurbit breeding. He replaced Jack Staub several years ago. The focus of
his program is on germplasm characterization and enhancement; genetics and genomics of important
traits in cucumber; development of molecular markers and applications in breeding practice; genetic
diversity, phylogenetics and comparative genomics in Cucumis species; development of cucumber
genomic resources. Weng projects at HARS include:
Fine genetic mapping of cp: a recessive gene for compact (dwarf) plant architecture in cucumber,
Cucumis sativus L
Spacing and genotype effect on fruit sugar concentration, yield, and fruit size of muskmelon
Inheritance of the Quantity of ß-carotene and Fruit Maturity of Melon (Cucumis melo L.)

15. Outreach
Outreach activities conducted at HARS provides the opportunity for interaction between growers and
industry with UW faculty, academic staff, students and HARS personnel. This interaction is essential for
the communication of advances on research to stakeholders. At the same time growers and industry
provide guidance to help align research priorities with the needs of WI agriculture. Outreach activities
conducted at HARS include.
Meetings with stakeholders organized as grower and industry association committees
Meeting with individual growers visiting the station
Collection of samples from individual growers to be sent to pathologist or entomologists on
campus
Annual WPVGA sponsored Potato Field Day
Annual Potato Variety Harvest Expo
Midwest Food Processors field day (snap bean and sweet corn)
A.R. Albert & Villetta Hawley-Albert Horticultural Garden Twilight tour
Potato growers and industry personnel evaluate new elite potato
breeding lines at the Annual Potato Variety Harvest Expo
A living proof that it is never too early
to observe research advances!
Final Remarks
The mission of the Hancock Agricultural Research Station integrating research and development for WI
Agricultural Systems is a service that the College of Agricultural and Life Sciences has understood from
the early years of the station. The College realizes the importance of research that addresses the needs
of growers and industry. Historically, researchers such as J.C. Walker, a member of CALS from 1919 until
his retirement in 1964 provided the proof of the value of research for agriculture. Walker developed
disease-resistant varieties of cabbage, onions, beans, peas, beets, potatoes and cucumbers. Several
times during the first half of the XX century, Walker's research prevented the collapse of key segments
of the state's multimillion-dollar vegetable processing industry. His research also made vegetable
production possible in many areas of the world where diseases previously had decimated crops. Today,
the College, growers and industry have developed infrastructure to make possible great advances in
research, student training and outreach. The integration of these elements are key to agricultural
development in WI and beyond, in agreement with the Wisconsin Idea.
