Applying 0.2% SAP in red soil, the saturated soil moisture content is 64.94% which increased 22.31% than control, the available soil water content is 41.35%, which increase 36.47% than control;

Applying 0.2% SAP in sandy soil, the saturated soil moisture contentis 34.78%, which increased 32.60% than control, the available soil water content is 30.90%, which increased 37.7% than control;

Water Available for Plants

Under 0.3 Mpa Suction section, it’s the aptest to utilize moisture by plant

Effectiveness in Soils

It can notably improve soil structure reduce soil bulk density and increase the soil porosity. In red soil, applying 0.1% 0.2% 0.4% , the soil bulk density decreased .33%, 11% 14.68%; in sandy soil, applying 01% 0.2% 0.4%, the soil bulk density decreased 9.35% ,12.95%, 15.11% , but two soil porosity increase with the increasing of SAP.
