Results of long-term observations of agrophysical parameters of alluvial meadow soil of the Sakhalin Island

Abstract

In the field crop rotation during three rotations, favorable agrophysical properties of alluvial meadow soil have been created and preserved, corresponding to the requirements of the crops included in it. The granulometric and structural differentiation of the arable soil horizon has been established. A decrease in the content of microstructural particles (<0.01 mm) was observed in the 0–10 cm layer. In this layer of soil, there was an increase in density, which was associated with a long-term mechanized action during forage harvesting. The soil structure in the arable layer of the output fields with perennial grasses had excellent ratings. The aftereffect of fertilizer systems did not significantly affect the value of agrophysical parameters.
