埴土에서 石炭灰 施用으로 土壤의 理化學性 變化 = Changes of Soil Physico-Chemical Properties by Application of Fly Ash to Clay Soils

다국어 초록 (Multilingual Abstract)

This study was conducted to investigate the influence of fly ash could fertilizers resource and soil improvement for agriculture used by upland was studied through clay soil. The upland field of treatments with five types were Non-fertilizer, N-P-K, Fly ash 40, 80, 120ton/ha. The results as follows.
1. pH value of soil was significantly showed high at fly ash treatments than non-fertilizer, N-P-K treatments and pH value high was be relation to contents of fly ash application
2. EC of soil was significantly high compared with non-fertilizer, N-P-K treatments by mineral of solution at fly ash treatments
3. Av.P_2O_5 of fly ash 40ton/ha treatment was tend to more or less increased than non-fertilizer, N-P-K treatments but fly ash 40, 80ton/ha treatments were high increased about 2∼3 times respectively.
4. The content of Exchanges cation tended to more and more increased by content of fly ash application to soil was increased, especially content of Ex-Ca was the best of height respectively.
5. The content of water solution boron in soils was similarity with non-fertilizer and N.P.K treatments, but fly ash treatments tended to increased than those.
6. Correlation between contents of fly ash application to soils and water solution boron, Ex-Ca, Mg, Av.P_2O_5, Ex-K were order showed 0.917", 0.877", 0.794", 0.588", 0.405' compared with N-P-K treatment.
