Analysis of approaches to increase the fertility of irrigated typical gray and meadow soils in Uzbekistan

Abstract

This research paper explores the effects of utilizing plant residues as mulch and applying various fertilizers on the fertility and key physical and chemical attributes of irrigated typical gray and meadow soils. The study demonstrates that these agricultural techniques significantly boost the development and productivity of winter wheat and cotton. It outlines how mulching with plant residues notably enhances soil fertility through increasing organic matter, optimizing soil structure, and minimizing erosion. The study further indicates that using organic fertilizers, including biohumus and bio-based preparations, augments soil fertility and fosters the activity of beneficial microbes within the soil. The investigation highlights the crucial role these methods play in elevating the growth and productivity of winter wheat and cotton. The conclusions drawn advocate for the combined use of mulching and fertilizers as a strategy to elevate crop outputs, enrich soil health, and promote sustainable farming methods in these soil types.
