Econometric analysis of the influence of climate characteristics on the ecological condition of soils and the productivity of agricultural crops

Abstract

An increase in air temperature causes water loss from irrigated areas due to evaporation. Such changes, in turn, increase the water demand of crops. High air temperature accelerates the natural decomposition of organic matter and causes a decrease in soil fertility. Furthermore, the probability of the spread of plant pests and diseases increases. This article presents an econometric analysis of the influence of climate characteristics on the ecological status of soils and the productivity of agricultural crops. The results of econometric modeling show that the constructed models can be used to forecast cotton yield for future periods. In Chimboy district (model 1), the influence of non-saline and weakly saline lands, groundwater level and relative air humidity on productivity was clearly demonstrated.
