Variability of Soils Water Infiltration Features

Based on the infiltration experiments of field soils,the temporal variation of water infiltration features of field soils were analyzed and discussed.The experimental results indicated that,the water infiltration features of field soils have great difference between different periods of tillage with preset soil texture.During agricultural production cycle,Infiltration capacity,infiltration velocity and rate of stability infiltration of field soils decreased while periods of tillage developed.The process of infiltration of field soils is different between different periods of tillage.The result is of practical meaning in determining the field irrigation technical parameters.
