Abstract

Air-dried soil samples were measured for hydroscopic water by microwave radiation method (new method)and oven drying method (traditional method).It was showed that measuring time for air-dried soil was shortened from 8 ～ 10 h (traditional method)to 8 min (new method), but no apparent differences in results were observed by t-test .It took 4 , 7 , 10 , and 12min respectively for air-dried soil of 5 , 10 , 15 , and 20 g to reach a basic steady status of hydroscopic water loss .Therefore the safety time for hydroscopic water determination of 5 ,10 , 15 , 20 g air-dried soil should be 5 , 8 , 10 , and 12 min respectively .It can be concluded that the microwave radiation has the advantages of saving time and energy and heating uniformly , and is an effective way to measure soil hydroscopic water .
