Abstract

This article outlines the principles of rational use of rapeseed agroecosystemÂ’s natural resources (soil and biological) in foothill zone conditions of southeastern Kazakhstan. It was determined that the methods of resource-saving technologies provide restoration of agrophysical factors of soil fertility, allow significant reduction of energy costs per unit of produced products. Due to the proper placement of rapeseed crop by best predecessors in the short rotational crop rotation cycle and due to proper timing and seeding rate, the eco-phytosanitary condition stabilizes and yield significantly increases. It was determined that effectiveness of the resource-saving technology of rapeseed cultivation, where the conventionally net income from application of rational resource-saving methods is 44.8 thousand tenge / ha, which raises the level of profitability of rapeseed cultivation to 76.4 % and the need for running tillage equipment is twice less. Use of resource-saving technology ensures the receipt of 25.1 thousand tons / ha of additional income per hectare. The possibility of rational use of resources and resource-saving in the agroecosystem has been determined for the first time. The research revealed recovered parameters of agrophysical values of fertility of soil resources, reduction of total energy expenses by 21.8-28.4% (fuel consumption) and obtaining 25.1 thousand tons / ha of additional income per hectare.
