Water resistance of soil during cultivation of leguminous perennial grasses
Journal Title: Наукові горизонти. Scientific Horizons - Year 2018, Vol 64, Issue 1
Abstract
At the end of the first year of vegetation of leguminous perennial grasses, the greatest number of water-resistant aggregates is observed when growing clover meadow – 91,7 % and lotus corniculatus – 88,7 %, and the lowest – 70,3 % with cultivation of alfalfa seedlings and sweet clover – 74,0 %. In the second year of vegetation, the total water resistance of soil aggregates in the cultivation of leguminous perennial grasses decreased in all grasses, except for the white clamor and the horned hare. In these herbages, the water resistance of soil aggregates, as compared to the first year of vegetation, increased by 21,3% for the white clover variant and by 1,3 % for the variant of the horned hare. Water resistance of soil aggregates in other variants decreased by 32,3–11,2 %, most of all – in alfalfa sowing and clover meadow, and least in sainfoin sand. On average, the water resistance of soil aggregates under leguminous perennial grasses at the end of the second year of vegetation was 48,0–95,3 %. It was the largest under the grass stand of the white clover and the horned lagoon, and the lowest one in the sowing alfalfa. At the end of the fourth year of vegetation of leguminous perennial grasses, the water resistance of soil aggregates of all fractions was 77,2–93,5 %. It was the largest on the variant of a horned hare, and the lowest on a variant of alfalfa sowing. n the fourth year of vegetation of leguminous perennial grasses, the water resistance of soil aggregates increases in comparison with their two-year growing, by 4,8–37,8 %, most of all on the variant of alfalfa seeding, and least on the variant of the horned lamb. In general, among all the years of research, the highest water resistance of the soil was observed in the fourth year of vegetation, and the smallest in the second year. Water resistance of soil aggregates after plowing of leguminous perennial grasses before sowing of winter wheat was 72,8-95,3 %. She was the highest in the area of the white clover and the horned hare, and the smallest after the alfalfa sowing season. Plowing of the soil led to an increase in the water resistance of soil aggregates after alfalfa seed, clover meadow, sainfoin sand and horseradish horned by 5,1–34,1 %. Most of all, the water resistance of the aggregates increased after the cultivation of alfalfa seed and clover meadow, and least of all after the horned lamb.
