Abstract

Abstract

En 中文
• The QUEFTS model determined optimal potato yield and nutrient requirements. • Remote sensing integrated with QUEFTS improved fertilizer use efficiency. • RF regression and Planet imagery monitored plant nitrogen accumulation. • Optimal N, P, and K needs were 1.86, 0.36, and 2.81 kg per tonne of tuber. • Variable fertilization reduced N and P application by roughly 12.8%.
