摘要
The effect was studied of the depth of fertilizer placement on the biological status of various layers of moderately thick Southern Chernozem in Saratov Oblast. Medium and deep placement of manure (16-30 cm) is shown to be preferable and favorable for the biological status, humus accumulation, and increase in yield.
