Effective methods of preventing degradation of desert pasture soils of Uzbekistan

Abstract

Natural desert pastures are the main source of fodder for the livestock of the republic, which allows them to use desert pastures all year round. In this research, effective agro-technical measures used to cultivate promising varieties of desert forage plants suitable for soil-climatic conditions was studied in order to improve the condition and increase the productivity of degraded desert pastures. Predictive methods were employed to development of agro-technical measures aimed at restoring, maintaining, increasing and protecting the fertility of sandy desert soils in improving the condition of desert pastures, and to implement a number of complex measures, such as overcoming the process of soil degradation. According to the results, The results showed that seeds of shrubs and semi-shrubs are sown at a depth of 1.5-2.0 cm, the norm of sowing the seeds of the same crop, salsola orientalis and haloxylon 6-8 kg/ha, male grass 5-6 kg/ha and other desert plants planted in accordance with regulatory documents. Once the seedlings began to germinate, field germination of seeds, number of seedlings and retention dynamics, development of adult plants, and formation of the root system were determined.
