Breeding and Seed Farming of Desert Forage Plants in Uzbekistan

The article provides a description of the best-zoned varieties of desert forage plants intended for the intensification of fodder production in the semi-desert and desert zones of the Republic of Uzbekistan. The features of agricultural technology for creating highly productive pasture agrophytocenoses in desert and semi-desert zones are given. In the breeding of desert fodder plants, traditional methods were widely used, which consider the biological characteristics of the reproduction of each particular species. The created local varieties of desert fodder plants contributed to the creation of highly productive pasture agrophytocenoses in the conditions of deserts and semi-deserts of Uzbekistan with fodder productivity of 19-27.0 q/ha of dry weight

Quantitative and Qualitative Characteristics of Organic Matter Under Long-Term Exposure to Natural and Anthropogenic Factors

Studies have found that the increase in differences between the amount of energy subsidies invested in agrobiocenoses and alienated from them over a 105-year period changes the direction of biochemical processes of organic matter transformation, which leads to significant losses of organic carbon reserves, which amount to 17.5 t/ha in highly degraded soils, 7.3 t/ha in poorly cultivated soils, and in highly cultivated increases them by 2.8 t /ha, respectively, compared with the initial content. Long-term use of arable land affects the qualitative characteristics of the state of organic matter of sod-podzolic soil, which are expressed in a change in the ratio of the peripheral and central parts, the enrichment of humus with nitrogen. The humus substances of medium (57%) and highly cultivated soils (54%) are characterized by the highest degree of participation of peripheral groupings in the construction, and the least highly degraded (29%)

Chapter 11 - Regional assessment of soil changes in Europe and Eurasia

In Europe and Eurasia, the inherent complexity and spatial variability of soil makes the evaluation of the impact of any change difficult. Transformations of features such as texture and mineralogical composition will only occur over geological time spans while properties such as pH, organic matter content or microbial activity will show a more rapid reaction. In addition, the response of a particular soil type may be both positive and negative depending on the function in question. For example, rising temperatures and precipitation may support increased agricultural productivity on soils previously deemed marginal, but such a transformation can lead to a deterioration of soil biological diversity and an increased risk of erosion. Quantitative assessments of future trends in soil characteristics and properties are limited. As a consequence, this chapter provides an outlook only for a selected number of issues. Considerably more effort is required to model changes in the state of soil conditions in relation to drivers such as changes in land use and climate. Based on the above finding, an assessment  is made of the status and trend of the ten soil threats in order of importance for the region. At the same time an indication is given of the reliability of these estimates.JRC.H.5-Land Resources Managemen
