Before the instrument was put in practical use, fundamental experiments were carried out on the operation of the instrument and its calibration. The sample was packed uniformly in drying box, and was tested in two cases : the thermostatic drying and the out-door drying. The experimental results are summarized as follows : 1. The boundaries transiting from drying in constant rate to drying in decreasing rate of three samples are seen respectively in water constant of about thirty percents, and the drying time required to nearly reach this soil moisture differs greatly with each sample and each depth. 2. Water content profile in soil layer varies with time. In this profile, the difference in water content so far 7∿10cm depth from upper surface becomes very large with time, but there is not so much difference in water content in the parts deeper than 10cm depth. 3. Thin film of drying above PF 5 is formed on the upper surface of erosive soil from Kunigami gravels in the short period. 4. From the results of drying box tests, it doesn't always follow that drying velocity of soil from Ryukyu limestone droughting frequently is large. 5. Cracks developed in the soil from Shimajiri mudstone cause the evaporation of surface to increase markedly and accelerate drying of the lower parts of layer. 6. PF value is to be known by using the glass block soil moisture instrument along with the PF- water content curve. For instant, under the cumulative global radiation of 9.5kcal/(cm)^2 that the soil layers recived in the drying test period, soil from Kunigami gravels was dried up to the PF 4.2∿5.0 of soil moisture, soil from Ryukyu limestone up to the PF 3.6∿5.0,and soil from Shimajiri mudstone up to the PF 3.8∿5.0.","subitem_description_type":"Other"},{"subitem_description":"\u7d00\u8981\u8ad6\u6587","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"\u7409\u7403\u5927\u5b66\u8fb2\u5b66\u90e8"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"jpn"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/4305"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"ISSN","subitem_1522646572813":"0370-4246"},{"subitem_1522646500366":"NCID","subitem_1522646572813":"AN00250548"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_1522650068558":"ja","subitem_1522650091861":"\u7409\u7403\u5927\u5b66\u8fb2\u5b66\u90e8\u5b66\u8853\u5831\u544a"},{"subitem_1522650068558":"en","subitem_1522650091861":"The Science Bulletin of the Faculty of Agriculture.
