How does the interaction between varying nitrogen fertilizer application rates and tillage depths influence nitrogen use efficiency, crop uptake, and residual nitrogen losses in different soil types and cropping systems?
Susan Weesa
The interaction between nitrogen fertilizer rate and tillage depth is complex and context-dependent, varying with soil type, climate, cropping system, and management practices. Optimizing these factors is crucial for enhancing NUE, ensuring adequate crop uptake, and minimizing detrimental residual N losses to the environment. Sustainable agricultural practices aim to find a balance that maximizes crop yields while minimizing the environmental impact of nitrogen fertilizers and tillage.
