SOME EFFECTS OF DEEP PLOWING AND FERTILIZING A SOLONETZIC SOIL UNDER IRRIGATION

A 5-yr study showed that deep plowing under irrigation is a promising reclamation procedure for Solonetzic soils containing a calcium-enriched Csk horizon within a depth to which the soil may be plowed. The liberal application of nitrogen-phosphate fertilizers on irrigated soils after deep plowing may cause leaching of calcium.
