The effect of humic fertilizer on soil fertility and corn yield in the conditions of Zhetysu

Abstract

Light sierozem of the south-east of Kazakhstan are characterized by a low humus content, weak structure and limited moisture capacity, which causes their relatively low level of natural fertility and limits the productivity of agricultural crops. In the context of agricultural intensification, an urgent task is to find environmentally safe and cost-effective ways to increase corn yields for grain. The present study evaluates the effect of organic humic fertilizer Atmas on the growth, development and productivity of corn. It has been established that the use of humic fertilizer stimulates plant development and increases the mobility of nutrients in the rhizosphere. This ensures a more intensive formation of the root system, improves the absorption of macro and microelements and helps to increase the resistance of plants to stress factors of the arid climate. As a result, grain yield increased to 13.2-15.9 t/ha, providing an increase from 4.7 to 26.1% compared with the control. Thus, Atmas organic humic fertilizer is an effective means of increasing corn productivity for grain in light sierozem, ensuring sustainable crop formation, improving the agrochemical properties of the soil and increasing the economic efficiency of crop cultivation.
