- Soil Fertility Dominates the Optimal Allocation of Basal and Tillering Nitrogen in Rice Production (2026) · Agronomy · doi
Excessive basal and tillering nitrogen (BTN) application in rice production causes substantial N losses and environmental costs, yet practical soil fertility thresholds to guide safe BTN reduction (RBTN) have not been established.

However, there is no more information on the relative impact of soil tillage practices on soil physical and chemical properties, microbial biomass, and enzymatic activity, and grain yield in a rice–ratoon rice cropping system remains to be tested.
