This research studied the quantitative effects of sand content on soil water-holding capacity by compounding different texture of soil.The results showed that:(1) Sand content had a great effect on soil water holding capacity.Soil water holding capacity was decreased with the increase of sand content.The parameters of Gardner soil water characteristic curve model A(stand for water holding capacity) and Van Genuchten model(stand for saturated water content) went down with the increase of sand content.(2) Soi...
