Abstract: Soil moisture and crop growth are important parts of characterization of agriculture information. Soil moisture directly influences the crops growth, and crops growth is closely concerned with crop yields. From the view of application, the monitoring sample points were set up, the monitoring content and evaluation indices were established and the network information platform was constructed through areal characterization of natural environment and crop distribution. Also the ground monitoring system of soil moisture and crop growth in large scale was constructed which realized administration of data networks. Combined with remote sensing information, the application of ground monitoring system can supply the decision-malcing support for government.
