This document discusses the development of an improved greenhouse gas inventory for UK agriculture. It outlines several activities across three projects aimed at better quantifying agricultural emissions:
1) Prioritizing measurement and data collection based on key uncertainties and knowledge gaps.
2) Gathering farm practice data and developing proxies to estimate emissions where direct measurement is not possible.
3) Conducting experiments to generate country-specific emission factors for methane from livestock and nitrous oxide from soils.
4) Standardizing measurement protocols and engaging in training and knowledge exchange between researchers.
The overall goal is to create an inventory tool that more accurately represents UK agricultural conditions and emissions over time to monitor progress towards emissions targets.

Ammonia and Nitrous Oxide Model for Open Lot Cattle Production SystemsLPE Learning Center
Full proceedings at: http://www.extension.org/72819 Air emissions, such as ammonia (NH3) and nitrous oxide (N2O), vary considerably among beef and dairy open lot operations as influenced by the climate and manure pack conditions. Because of the challenges with direct measurements, process-based modeling is a recommended approach for estimating air emissions from animal feeding operations. The Integrated Farm Systems Model (IFSM; USDA-ARS, 2014), a whole-farm simulation model for crop, dairy and beef operations, was previously expanded (version 4.0) to simulate NH3 emissions from open lots. The model performed well in representing emissions for two beef cattle feedyards in Texas (Waldrip et al., 2014) but performed poorly in predicting NH3 emissions measured at an open lot dairy in Idaho.

Phytogenic or Petrogenic Hydrocarbons - Using Biomarkers for DelineationChemistry Matters Inc.
Presentation on the use of petroleum biomarkers for delineation of petroleum impacts in a high organic soil area (muskeg). Phytogenic hydrocarbons are natural compounds that are misidentified by standard analytical methodologies of high organic content soils as petroleum hydrocrabons. This artificially biases the measurements high for organic rich soils. Petroleum hydrocarbon products have distinct petrogenic biomarkers that can be used to identify if a sample contains petroleum or not. These biomarkers were used in this presentation to determine where petroleum impacts in the soil end and limit the unnecessary excavation of a muskeg chasing samples that were above guidelines due to the presence of natural hydrocarbons. Presentation shows how environmental forensics and petroleum forensics investigations can be used in an environmental site assessment.

For more: http://www.extension.org/67579 A new method was used at the Ag 450 Farm Iowa State University (41.98N, 93.65W) from October 24, 2012 through December 14, 2012 to assess GHG emission from land-applied swine manure on crop land. Gas samples were collected daily from four static flux chambers. Gas method detection limits were 1.99 ppm, 170 ppb, and 20.7 ppb for CO2, CH4 and N2O, respectively. Measured gas concentrations were used to estimate flux using four different models, i.e., (1) linear regression, (2) non-linear regression, (3) non-equilibrium, and (4) revised Hutchinson & Mosier (HMR). Sixteen days of baseline measurements (before manure application) were followed by manure application with deep injection (at 41.2 m3/ha), and thirty seven days of measurements after manure application.
This presentation summarizes the findings of an air emissions and odour sampling program conducted on the Baytex Reno Field. The data was collected in response to local resident complaints of odours in the area. The study collected samples using industry standard procedures and analyzed by state of the art analytical equipment. The results showed that no human health effects were exceeded and that no odour thresholds were exceeded. This study exemplifies how odours may be detected even though the standard analytical practices are not able to measure the odiferous compounds. PAHs were measured in the study and show a petrogenic ligher signature present the ambient air in the region as well as diesel markers from the trucking activity. This summary report was presented on January 22, 2014 to the Peace River AER Public Proceeding (1769924).

We conducted a field study on corn to evaluate the effect of liquid dairy manure applied pre-plant (injection or surface broadcast with immediate or 3-day disk incorporation) or sidedressed at 6-leaf stage (injected or surface-applied) on emission of NH3 and N2O. Manure was applied at a rate of 6500 gal/acre, which supplied an average of 150 lb/acre of total N and 65 lb/acre of NH4-N. Ammonia emission was measured for 3 days after manure application using the dynamic chamber/equilibrium concentration technique, and N2O flux was quantified using the static chamber method at intervals of 3 to 14 days throughout the season. Ammonia-N losses were typically 30 to 50 lb/acre from pre-plant surface application, most of the loss occurring in the first 6 to 12 hours after application. Emission rates were reduced 60-80% by quick incorporation and over 90% by injection. Losses of N2O were relatively low (1 lb/acre or less annually), but pronounced peaks of N2O flux occurred from either pre-plant or sidedress injected manure in different years. Results show that NH3 emission from manure can be reduced substantially by injection or quick incorporation, but there may be some tradeoff with N2O flux from injection.

Dr Bill Slattery of the Department of Climate Change explains the 'whole cycle' greenhouse gas accounting for enterprises which on the evidence - offers carbon farmers hope that a proper accounting for the volumes of soil C they can sequester, they will always be net sinks.
Measurement of soil carbon is the focus of attention of present and future international conventions and agreements, related to global climate change. Past inventories and current carbon stock inventories involve different analytical methods, and methodological biases and uncertainties should be reduced to develop reliable estimates of the effects of land uses changes on total organic carbon. Furthermore, the carbon-equivalent is highly variable, and there is the need of using a specific correction factor for each location, resulting from the combination of land use, textural gradients, and sampling depth. In this context, the aims of this study were creating correction equations for the determinations through wet combustion (Walkley-Black- WB) for a Rhodic Hapludox based on the determinations made through dry combustion (CS) at different depths and management systems. The experimental design was 4 x 5 factorial with 3 replications. Treatments were: Conventional Tillage (CT); Minimum Tillage (MT); No-till with chisel plowing (NTC) and No-Till (NT). The collection depths were: 0-2.5; 2.5-5; 5-10; 10-20 and 20-40 cm. The measured carbon equivalent values ranged from 1.06 to 1.18 and were dependent on land use and soil depth. Rhodic Hapludox under different management presented the following order of carbon equivalent values: NTC < CT < NT < MT. The carbon equivalent values increased with depth. The high ratio between C-WB and C-CS (R2= 0.75, p= 0.0001) justifies the use of correction factors.
Environmental Impact Assessment of Kota Super Thermal Power Station IJSRP Journal
Environmental Impact Assessment (EIA) is an important management tool for ensuring optimal use of natural resources for sustainable development. A beginning in this direction was made in our country with the impact assessment of river valley projects in 1978-79 and the scope has subsequently been enhanced to cover other developmental sectors such as industries, thermal power projects, mining schemes etc. To facilitate collection of environmental data and preparation of management plans, guidelines have been evolved and circulated to the concerned Central and State Government Departments. EIA has now been made mandatory under the Environmental (Protection Act, 1986 for 29 categories of developmental activities involving investments of Rs. 50 crores and above. In present study we have studied environmental aspects of kota super thermal power on Kota city.The KSTPS in Rajasthan was commissioned in 1983 and presently operating at 1045MW capacity,The Kota Super Thermal Power Station came in five stages and a total of 7 units have been commissioned.KSTPS is situated at the left bank of “Chambal River” in Rajasthan principal industrial city Kota.The present total area covered under KSTPS is 688 ha.The power generation system comprises mainly boiler, turbine, generator and transformers with accessories all arranged to operate as complementary parts of a common monolithic set.The allowable limits for discharge of water as specified in Schedule 4 of Environmental Protection Act And Amendment 1983 isAmmonical Nitrogen 50,Arsenic-0.2,Biochemical oxygen demand-30,Cadmium -2, Chemical oxygen demand -250, Chromium hexavalent-0.1, Chromium total-2, Copper-3,Cyanide-0.1,Fluoride-2,PH-5.5-9.0Phenols-1,Dissolve Phosphate -5,Residual Chloride 1,Sulphide 2,Total Suspended Solid 100,Zinc 5.0 . Various effluent samples are analysed to assess the effluent quality from KSTPS.Any major industrial activity have tendency to degrade the environment viz. air environment, water, noise, land and biological also. It is duty of every industry it should have its own environmental unit that allow to minimum quantity of pollutants emit into environmental and keep this pollutant range with in permissible limit described according to central and state pollution control board and MOEF. So we should think in the terms of sustainable development means development without destruction.
CAN CROP MANAGEMENT IMPROVE EMISSIONS SAVINGS?: PRELIMINARY RESULTS OF THE OP...Bioenergy Crops
Several studies suggest that lignocellulosic energy crops for electricity production may have a better performance compared to those crops for liquid biofuels production, when assessing GHG savings with respect to fossil references. Winter cereal residues and some annual winter grasses, as dedicated energy crops, are currently being grown in Spain and harvested as bales to be burned for electricity production in biomass power plants. Previous studies of our group analyzed GHG emissions and energy balances of winter cereals for electricity production by means of Life Cycle Assessment. We selected highly productive genotypes of three annual winter cereals (rye, triticale and oat) and compared them with Spanish electricity produced using natural gas. This paper compares effects of the use of different crop management practices for rye growing in the assessment of energy balances and GHG emissions. We analyzed the effects of six different management practices consisting of two different sowing doses (suboptimal and normal) combined with three top fertilization doses (zero, 30 and 80kgN ha-1). We made a characterization analysis of biomasses to estimate the nitrogen uptake of the crops in order to compare it with the nitrogen provided by the fertilizers. This comparison evaluates if lower fertilization doses are sustainable for the soil nitrogen stocks. Our results suggest that there is trade-off between soil nitrogen and emission savings. The use of zero or low top fertilization doses (30 kg N ha-1) improves GHG emissions and energy balances even with a yield reduction. Nevertheless the use of these doses imply an annual lose in soil nitrogen stocks for the majority all of our trials. Using suboptimal sowing doses resulted in yield decreases that did not compensate the lower input consumed.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!
Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Proxies
• Not everything can be measured! – how else to monitor change
• Assess proxies for N2O from soils and CH4 from enteric fermentation
• Link with modelling activities
N2O
National/regional scale – e.g. OECD N balance, N use efficiency
Farm scale – e.g. farm gate N balance, uptake of mitigations,
Field scale – e.g. soil characteristics, crop yields
CH4
e.g. diet characteristics, fed conversion efficiency

monitored 365 days Sept 07 (following sowing) till sept 08 (harvest). Fan used to facilitate mixing
in chamber headspace. Deployment time usually 1.5hrs, measurements with chamber inter-sections
extended to max 3hrs. Foulum chambers - 0.75x0.75m; Flakkebjerg - 0.6x0.6m base. Gas samples
taken through septum, evac vials, 09.00-14.00 each sampling day. 1st sample taken immediately
after installing cover. GC and ECD (GC-14B Shimadzu - Flakkebjerg; Chrompack CP9001-

N2O measured using Smith et al (95). Chambers - 52x52x15cm high square collar inserted
permanently into soil over which 50x50x30cm high lid with plastic septum could be sealed. Gas
linearity in chamber was tested. After lids in place an initial gas sample taken, 2nd and 3rd at
30/60min. sampled every weekand more intensively during fert periods. Samples taken in morning
between 9-11am. Samples taken with syringe after flushing syringe and mix air within chamber; then
injected to pre-evac vials. GC 14B Shimadzu with ECD.

Air tight lid, 30min centre bung fitted, gas sample taken through
a septum in lid, 10mL headspace flushed 4 times through a
6mL septum-sealed glass tube. 2nd gas sample taken 30min
later. N2O - gas chromatograph. 2003 samples stored for
7months - no sign of leakage
Weekly N2O rates calc for each soil cover from the increase in N2O conc of the headspace over time.
Cumulative N2O then calc by averaging N2O emission rate of the 3/4 soil covers per plot, followed
by linear interpolation of the weekly msmts over time. Average N2O emis for each treatment was calc
from the geometric means of the intergrated emis, then log-transformed and ANOVA of randomised
blocks to determine differences btw treatments for each yr as well as for the 3yr period
