Assessment of the impact of convergent processes on crop productivity during land reclamation

The purpose and direction of this study is to develop a scientifically based methodology for assessing the impact of convergent processes on moisture demand and crop yields during land reclamation. A related goal is to develop an algorithm for designing and managing technological processes for purposeful, environmentally sound reclamation of agricultural land under prevailing climatic and economic conditions. The productivity of agricultural crops is a material result of adaptive breeding, a combination of agricultural technologies, irrigation and drainage technologies, soil layer productivity, emerging climatic factors and humidity conditions in ecotopes of the agrocenosis. Irrigation reclamation technologies serve as a source of influence and a regulating factor of ecotopes in environmental management, and have the most positive effect on the level of crop productivity compared to other agrotechnical measures, especially for arid climate conditions. To assess the effectiveness of irrigation reclamation, it is recommended to use methods for determining the optimal ranges of values for complex factors of convergent processes. The most important factor is the water demand of agricultural crops in specific natural and economic conditions of the agrocenosis – a scientifically based integral indicator for calculating the parameters of the irrigation regime, taking into account its impact on the projected yield. The models of predicted productivity developed taking into account the recommendations on cultivated crops make it possible to describe the dynamics of plant water consumption in the given conditions of agro-reclamation activities on irrigated lands and to obtain justification for criteria for evaluating the effectiveness of convergent technologies affecting the water demand of crops and agrocenosis (agrosystem) in environmental management.
