objectives of this thesis were to study and compare the ability of Brookston loam, Genesee loam, Kalamazoo sandy loam, and Landes-Abscota sandy loam to release and/or fix soil potassium under different cropping programs, and to relate these phenomena to their physical, chemical, and mineralogical properties. Five levels of potassium, 0,200,400,800 and 1,600lbs per acre were applied initially to all soils and the soils were planted to 6 crops in the following sequence : 3 crops of wheat, 2 crops of sorghum, and 1 crop of tomatoes. Plant response to the applied potassium, the interrelationships among potassium, calcium, and magnesium uptake of the plants were investigated and the potassium supplying power of the soils were evaluated. The 3rd crop (wheat) and the 6th crop (tomatoes) grown on Brookston loam were the only crops to show a yield response to the potassium treatments. In the case of Genesee loam the 3rd crop (wheat) and the succeeding crops, 2 crops of sorghum and 1 crop of tomatoes, responded to the potassium treatments. The plant response obtained from applied potassium on Kalamazoo sandy loam was the same as that obtained for Genesee loam, but the yields of the 2nd crop (wheat) was negatively affected by the potassium treatments. All crops except the 2nd (wheat) grown on Landes-Abscota sandy loam responded to applied potassium. Potassium concentration of the plants rose with increasing levels of applied potassium while the concentrations of plant calcium and magnesium generally decreased. Potassium concentration in the plants declined as the cropping advanced whereas that of calcium and magnesium increased. Potassium uptake of the plants grown on all the soils was significantly affected by potasslum treatments. However, plant uptake of calcium and magnesium varied with the crop and soils. Plant yields were generally positively correlated with potassium uptake and with the uptake of potassium plus calcium and mangesium, but negatively correlated with uptake of calcium and magnesium except for the 6th crop (tomatoes) in which the yields were positively correlated with all uptake measurements. The overall potassium supplying power, as measured by potassium uptake of the plants at the 0 potassium treatment, was in the following order : Brookston loam > Kalamazoo sandy loam > Landes-Abscota sandy loam > Genesee loam.","subitem_description_type":"Other"},{"subitem_description":"The stem tissue of wheat (2nd crop) was analyzed by the elecron microprobe X-ray technique. A higher concentration of potassium but a lower concentration of calcium and magnesium was obtained for the sample from the 400 potassium treatment on Brookston loam; on the other hand, a lower concentration of potassium but a higher concentration of calcium and magnesium was obtained from the 0 potassium treatment on Genesee loam. Chemical properties of the soils were studied in relation to potassium availability by determining exchangeable and nonexchangeable forms of potassium, the release and fixation of potassium upon wetting-drying, and freezing-thawing treatments, and quantity-intensity relationships of soil potassium. After 5 croppings the levels of exchangeable soil potassium for all soils were found to be considerably less than that of the original soil levels. Nonexchangeable potassium was retained at levels higher than the original levels, even after 5 croppings, when potassium was initially applied to the rate of 400 or more pounds of K per acre on Brookston loam, Genesee loam, and Landes-Abscota sandy loam, and at the rate of 1,600lbs of K per acre on Kalamazoo sandy loam. The applied potassium seems to have been converted to nonexchangeable forms and then released gradually upon the depletion of exchangeable potassium by the plants. The rate of potassium release was considered to be more rapid for Kalamazoo sandy loam, which had the lowest potassium fixing and cation exchange capacities among the soils. When the soil was incubated for 13 months with the various levels of applied potassium b","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":"eng"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/4459"}]},"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.
