Any decrease in non-beneficial water consumption must result in increased production per unit of consumed water. Increasing the efficient water use by cultivated soybean Glycine max (L.) Merr. requires an accurate assessment of moisture reserves in agrophytocenosis at different seasons. The aim of the work was to assess the content of soil moisture in different soil hori-zons of agrocenoses in the 0-150 cm layer in years with different meteorological conditions, including separately for the arable layer and subsurface horizons.
