Verifying the role of water superabsorbent polymers on several properties and productivity of winter crop in degraded soil area
Water superabsorbent polymers applied in degraded soil area improved some chemical and physical properties of soil, increased water holding capacity, maintained soil moisture and aggregation. They increased sorption capacity of K of soils and P displacement. Water superabsorbent polymers at a rate of 50 kg/ha, provided plants with better growth and higher yield. The productivity of dry seed increases 23% for peanut, 20% for soybean, 11% for corn.
