Influence of the ratio of land in agroforest landscapes on the productivity of agricultural crops

Lack of moisture and high temperature lead to a decrease in crop yields. According to a number of researchers, the solution to this problem is implemented in an integrated approach, an important link of which is agroforestry. To study the effect of the ratio of agricultural land in the Krasnodar Territory on soil fertility in agroforestry landscapes, we conducted research in 2022. The research was conducted according to generally accepted methods. The condition of the lands of the agricultural landscapes of the districts was assessed according to literary sources and statistical data. The allocation of fertility zones was carried out according to the normalized vegetation index NDVI. The purpose of the research is to study the influence of the ratio of land in agroforestry landscapes on the productivity of crops in the Krasnodar Territory using the Agronomist Online program based on the Sky Scout service. As a result of the research, it was found that a higher percentage of the fertile zone category for all agroforestry areas belongs to the middle category and accounts for 46.09% of the total arable land area of the region. In the second agroforestry district of the Krasnodar Territory (Seversky district), there is a higher percentage of land with a high level of fertile land of 29.63%. In this area, there is also a higher percentage of arable land cover – 3.12. The analysis of the fertility of agroforestry landscapes revealed a linear dependence on all research options. A closer relationship between the yield of winter wheat (2010–2022) and the protective forest cover of arable land is noted for the Seversky district, the regression equation for which has the form y = 1.6622 x – 3307.9 with R2 = 0.5745. Thus, it follows from the presented research results that in order to increase productivity (fertility) in the Krasnodar Territory, it is necessary to additionally create protective forest plantations. The choice of the land ratio should be carried out using an adaptive landscape approach. This approach will contribute to obtaining additional agricultural products, as well as the formation of optimal forest cover, conservation, and improvement of the ecology of agricultural lands in the agro-industrial complex of the region.
