Summary
Organic and conventional cropping systems differ in type and amount of nitrogen (N) inputs, which may affect efficiency and sustainability of N use. Organic N fertilizers such as animal manure differ from mineral N fertilizers in the supply of available N over time. Nitrogen budgets based on field data records of long-term experiments enable the determination of Use be crops over decades.
