The use of crop sensors for precise fertilization

Abstract

The paper presents the results of research on the use of ISARIA and OptRx sensors for the analysis of plant optical properties for precision fertilization. It was found that using the ISARIA and OptRx sensors of plant optical properties, it was possible to detect differences in the development of spring wheat crops. Consumption of OptRx mineral fertilizers in 2016 using precision fertilization of spring wheat and using plant optical analysis sensors was 3.5% higher, and in 2017 and 2018, respectively, 1.1 and 3.5% lower than in conventional intensive technology. Consumption of ISARIA mineral fertilizers in 2016 and 2018 using sensors were 0.5 and 0.6%, respectively, higher, and in 2017 it was 4.6% lower than in conventional intensive technology.
