Shuitu Baochi Xuebao, 2017 为确定添加生物质炭对旱作农田土壤持水特性的影响，在隆中黄土高原典型旱作农田区设置相关定位试验，对不同生物质炭输入水平的土壤容重、土壤孔隙度、土壤水分常数及土壤水分特征曲线进行测定。结果表明，生物质炭的添加能够减小土壤容重，增加土壤孔隙度。随着生物质炭输入水平的增加，土壤容重的减小及土壤孔隙度的增加幅度加大。生物质炭达到50 t/hm2时土壤结构变化最为明显，0—5，5—10，10—30 cm土层中土壤容重相比对照分别减小7.01%，9.91%，16.60%，土壤毛管孔隙度分别增加19.47%，21.02%

Shuitu Baochi Xuebao, 2002 用张力计法测量了黄白土的持水特性及施用有机物料对黄保水和供水性能的影响。结果表明：（1）在张力计测定范围内，黄白土土壤水吸力与含水量之间表现出显著的线性相关。（2）施用有机物料，可以提高土壤的保水性能。其中施用牛粪的效果要优于麦秸。施用有机物料，还可以提高土壤速效水的上限，降低速效水的下限，提高速效水的含量，增强土壤水的有效性。
