Soil moisture monitoring plays an important role in agricultural production and scientific researches, so automatic soil moisture measurements are widely applied. The operational verification process of the new DZN3 type automatic soil moisture station is introduced. The report rate of automatic observation data and the determination of soil constant are analyzed and compared with the manual observation data in detail. Automatic soil moisture observation stations that can put into operation are confirmed through the way of contrast testing. The reasons for failing to pass the test are also analyzed, and some suggestions are given for future operational tests.
