The mathematics model for the relationships among soilavailablewater content with soil texture, particle diameter and dosage of super absorbent ploymer(SAP) was deduced.
Soilavailablewater capacity (AWC) plays an important role in the evaluation of drought resistance of soil, planning and managing water resources and conducting irrigation.
土壤有效含水量(AWC)是评价土壤抗旱性、水资源规划和管理以及指导灌溉的重要依据。

Though the wilting coefficient of soil tend to increase as water retaining agents increased, the amplitude was low, so the soilavailablewater capacity augmented obviously.
