Title Economic effects of technologies aimed at improving soil quality on low salinized irrigated lands in Uzbekistan
Author ATI Vol13_issue2-4_33
Abstract
One of the most painful issues in the Uzbek agricultural sector today is soil degradation of irrigated lands. This paper aims to highlight the importance of sustainable crop rotation and protection of soil mainly from the economic perspective. The research was performed on low salinized irrigated lands to determine the most profitable technology taking into account conservation agriculture techniques. The measures of the new technology include increased doses of organic fertilizers, diversification of crops in the traditional system of cotton – wheat rotation to protect the soil, and the use of plant residues as a source of humus to increase soil fertility and to disable the process of salinization. The economic effects were rather positive: increased yields, lower costs of mineral fertilizers, and additional revenues from intermediate crops. On the other hand, extra labour costs and lack of organic fertilizers are the downsides of the new technology.
