Abstract:
Based on the results of the study, criteria for the selective introduction of suitable secondary
crops (beans, mung bean, soybeans) and perennial alfalfa and mineral fertilizers were selected,
which reduce the negative effects of irrigation erosion, increase soil fertility, and ensure the
production of high-quality grain from winter wheat. The results show that, after repeated crops,
the volume mass of the 0-30 cm layer of soil is 0.03-0.05 g/cm3 less than in the case of
unwashed soils compared to the initial value, the porosity is 1.9-2.5% higher, in heavily washed
soils respectively 0.02-0.04 g / cm3 less and 1.7-2.3% higher, compared to the control of soil
water permeability 38.3-51.2 m3 / ha and at the end of the period of application 24.9-42.7 m3
Grain yield in unwashed varieties under the influence of repeated crops and mineral fertilizers
(N150P105K75 kg / ha), providing favorable conditions for full germination, growth and
development of winter wheat seeds (92.3-91.5%), providing grain yield in unwashed soil
variants (68.8-72.4 c/ha), protein content from 14.8-15.6 and gluten 31.8-32.4%, mineral
fertilizers (N180P126K90 kg/ha) after repeated sowing of the above in areas with strongly
washed soils in the applied variants are 69.2-74.5 c/ha, 15.2-15.8 and 32.1-32.8%, respectively,
plays an important role in ensuring food security of the population during the current coronavirus
