As a supplement of the previous report, soil samples from 10 locations in Ishigaki Island were tested by Spurway Soil Test Kit for the purpose stated in the previous report. 2. All of the soil samples contained 3 to 6 p.p.m. of magnesium. 3. Soil samples in four locations gave low reserve test results for iron which indicate the possibility of iron deficiency for crops. The upper horizons have a tendency to show a low content in iron. This suggests that in the early stages of growing plants, an iron deficiency may be found. 4. Samples from five locations gave low active test results in manganese which indicate the possibility of mangaese deficiency. 5. Test results for sulfates were negative in all soil samples. However, soils may not be deficient in sulfur because the lower limit of the sulfate test of the Spurway Soil Test Kit is 20 p.p.m. 6. In addition to the tests on above elements, the following tests of elements were made: a) Most soil samples showed low test results for available nitrogen. b) All soils except one were also low in phosphorus content which indicate the need for heavy phosphorue fertilization. One sample gave a high test result. It is supposed that the fixed phoshorus resulting from past phosphorus fertilizer applications might have caused such a high test result. c) Generally, most soil samples gave high reseve test results in potassium. However, these same samples gave negative test results for active potassium. Therefore, short period crops or crops which have weak absorption power of potassium may need soluble potassium fertilizers. d) Aluminum, chlorides and nitrites were all below toxic levels. 7. Other elements besides the above were not examined because the Spurway Soil Test Kit does not include such testing methods.","subitem_description_type":"Other"},{"subitem_description":"紀要論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"琉球大学農家政学部"}]},"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/20.500.12000/21950"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"ISSN","subitem_1522646572813":"0370-4238"},{"subitem_1522646500366":"NCID","subitem_1522646572813":"AN0025056X"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_1522650068558":"ja","subitem_1522650091861":"琉球大学農家政学部学術報告"},{"subitem_1522650068558":"en","subitem_1522650091861":"Science bulletin of Agriculture & Home Economics Division, University of the Ryukyus"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueNumber":"3","bibliographicPageEnd":"146","bibliographicPageStart":"139"}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1617265215918":{"attribute_name":"Version Type","attribute_value_mlt":[{"subitem_1522305645492":"NA","subitem_1600292170262":"http://purl.org/coar/version/c_be7fb7dd8ff6fe43"}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","filename":"No3p139.pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://u-ryukyu.repo.nii.ac.jp/record/2006628/files/No3p139.pdf"},"version_id":"8f6415b4-c6c6-4e5b-aa09-b7b374defe39"}]},"item_title":"琉球産土壤の微量要素に関する研究　1.
