Assessment of anti-deflation stability of sandy and loose sandy loam soils of arable lands of the Republic of Belarus

Abstract

The article provides an assessment of the resistance to deflation of sandy and loose sandy loam soils of arable lands. The average content of stable aggregates (larger than 1,0 mm) in sandy soils was 10,2–12,8 %, and in loose sandy loam soils – 31,6–33,8 %. All studied sandy soils, regardless of their type and degree of moisture, have unsatisfactory anti-deflation resistance. The share of loose sandy loam soils with unsatisfactory stability was 95,0 %, and with satisfactory stability – 5,0 %. Based on the statistical processing of data on the structural state of sandy and loose sandy loam soils, it was established that the content of deflation-resistant aggregates does not depend on their type and degree of moisture, but is determined, first of all, by the granulometric composition.
