Influence of Biochar on Sandy Soil Hydraulic Characteristic Parameters and Moisture Holding Properties

TIAN Dan,QU Zhong-yi,LI Bo,LV Yi-jia(College of Water Resources and Civil Engineering,Inner Mongolia Agricultural University,Hohhot 010018,China)  
The effects of biochar on sandy soil hydraulic characteristic parameters and moisture holding properties were studied to reveal the water-saving and fertility maintenance mechanisms of biochar.The results showed that the application of biochar could change the sandy soil structure and increase soil density with the increase of adding amount of biochar.Saturated hydraulic conductivity were smaller than the control group and saturated water capacity was larger than the control group in different biochar treatments.In the same water potential cases,water holding capacity improved along with the increase of biochar content,and the influences of different kinds of biochar on soil hydraulics parameters were inconsistent.
