March 8: Managing Field Nitrogen & GHG
– learn how farms can help reduce nitrous oxide (N2O - a potent greenhouse gas) emissions in cropping systems– with a focus on managing organic (manure, legumes etc) sources of nitrogen.
Managing Organic Nitrogen for Greenhouse Gas Reduction – Thinking critically about different sources of N, different soils, and different cropping systems to reduce nitrous oxide emissions from food production systems presented by Dr. Armen Kemanian (Professor, Production Systems and Modeling, Department of Plant Sciences at Penn State University)
Documenting and Managing Field Nitrogen Use for Greenhouse Gas Reduction presented by Dr. Quirine Ketterings (Professor of Nutrient Management in Agricultural Ecosystems at Cornell University).
“Adaptive Management” is an iterative strategy where farmers identify opportunities for improvement in production and environmental footprints, evaluate a management change on their own farm, through on-farm research and/or annual performance assessments. Whole farm nutrient mass balance (NMB) assessments is such an annual performance tool at the whole farm level while field nutrient balances are evaluation approaches at the field or within-field scale. The adaptive management strategy for field crop management introduced in NY in 2013, affords farm autonomy and decision making for site-specific problem solving and tracks issues and successes. When farms share results of the on-farm evaluations, successful strategies can be expanded to more fields and farms. Combined, anonymized data from participating farms can help identify practices and policies that incentivize improvements over time. While these whole farm and field-level tools were developed for nitrogen and phosphorus management with focus on water quality impact, reduction of N use will also reduce nitrous oxide emissions – a potent greenhouse gas.
