Use of Filters in Drainage Control Structures to Reduce the Risk Associated w...LPE Learning Center
For more: http://www.extension.org/67605 In livestock producing areas, animal manure is often applied to cropland to enhance soil fertility. Guidelines have been developed for manure application on fields underlain by subsurface (tile) drainage systems. Some of these guidelines, such as avoiding manure application if rain is predicted and not applying manure over a flowing tile, though effective, involve some level of risk. We believe that the level of risk can be reduced by filtering contaminants from the water leaving the drains. The control structures recommended for use with drainage systems underlying fields to which manure is applied, provide ready-made receptacles for filters. In this report we discuss the development and testing of a filter to remove contaminants from lagoon effluent.

For more: http://www.extension.org/67691 Water management in the crop root-zone is crucial to successful crop growth and production. Irrigation, surface, and subsurface drainage—and other practices—are routinely implemented throughout the world to improve crop productivity and working conditions of the soil. Water management practices also impact the environmental footprint of agricultural systems by affecting the flow of water, nutrients, sediment, and other constituents through field, farms, and watersheds. Water management practices for agriculture in the Midwestern US should be designed with both profitability and the environment in mind. The design of subsurface (tile) drainage systems has traditionally been more a matter of how much drainage one can afford, rather than the aforementioned objectives. The relationship among subsurface drainage design characteristics (depth, spacing, layout), farm profitability, and environmental impact are not well known at the farm scale. Thus, drainage system design may fail to meet one or more of these important objectives. This presentation will examine the effects of subsurface drainage system design criteria on productivity, profitability, and the environment, using the soils and climatic conditions of the northern corn-belt (southern Minnesota).

Lindsay Gardner - Southeast Aquatics Resources Partnershp
Nothing is more important than water for human health and the health of our fish and wildlife resources. Clean water and abundant habitat are critical to functional aquatic ecosystems with healthy populations of fish and wildlife. Successful aquatic resource conservation at the watershed level requires a multipronged approach working with local communities to restore ecologically impacted or impaired streams and put land use/habitat protections in place. The collaborative efforts of the Southeast Watershed Forum (SEWF), Southeast Aquatic Resources Partnership (SARP), The Nature Conservancy (TNC), the Environmental Protection Agency (EPA), U.S. Fish & Wildlife Service (USFWS), Georgia Wildlife Resources Division (GWRD), and other key partners in the Raccoon Creek area of the Etowah River Watershed, Georgia, an EPA priority watershed, provide a positive example of this holistic approach to watershed management. Building on the conservation planning, land protection and restoration efforts by TNC on Raccoon Creek, this partnership is successfully working with Paulding County stakeholders to identify conservation priorities and align watershed and conservation planning with county land use planning to ensure long-term benefits for prime habitat and water quality. This work encourages conservation-oriented growth practices and habitat protections to benefit fish and wildlife, like the Cherokee darter, and supports the regional habitat objectives of the SARP-directed Southeast Aquatic Habitat Plan, addressing threats to aquatic resources and key habitat protections. An outstanding example of how on-the-ground restoration of aquatic resources at the local level, the project also addresses national conservation priorities and demonstrates how through community-supported land use quality growth planning it is possible to develop a strategy and stewardship ethic to maintain these resources for generations to come.

UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.

The objective of this work is to contribute to valorization de Nephelium lappaceum by the characterization of kinetics of drying of seeds of Nephelium lappaceum. The seeds were dehydrated until a constant mass respectively in a drying oven and a microwawe oven. The temperatures and the powers of drying are respectively: 50, 60 and 70°C and 140, 280 and 420 W. The results show that the curves of drying of seeds of Nephelium lappaceum do not present a phase of constant kinetics. The coefficients of diffusion vary between 2.09.10-8 to 2.98. 10-8m-2/s in the interval of 50°C at 70°C and between 4.83×10-07 at 9.04×10-07 m-8/s for the powers going of 140 W with 420 W the relation between Arrhenius and a value of energy of activation of 16.49 kJ. mol-1 expressed the effect of the temperature on effective diffusivity.

"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.
