Yields and inputs evaluated together
Agronomic knowledge can help produce using nitrogen more efficiently, adapting interventions to crops and soils.
Research and local documents ↓What the evidence tells us
The program studied by Cui and colleagues in China reports increases in yields of 10.8— 11.5% and reductions in nitrogen use of 14.7— 18.1%, depending on the crop considered.

The diagram compares choices and conditions for putting them into practice. Measured outcomes and their limits are discussed in the evidence.
Research and local documents ↓Conditions and limits
They are the results of a specific program, not a guarantee for each field. Evidence, diffusion, and cumulative surfaces have different meanings.
Other possible benefits
Access to knowledge and lower loss of resources in production.
