有機性 廢棄物이 田土壤改良 및 大豆와 大麥收量에 미치는 影響 = Effects of Organic Wastes on the Physico-chemical Improvement Upland soils and the Growth and Yield of Soybean and Barley

국문 초록 (Abstract)

廢棄 有機物資源인 生藁, 堆肥 및 有機質粕을 砂壤土와 微砂質 埴壤土에 施肥水準을 달리하여 大麥과 大豆를 栽培하면서 土壤의 物理化學性 變化와 作物生育을 調査하였다.
有機物資源 施用으로 土壤의 假比重, 孔隙率, 硬度, 通氣性 等 物理性이 對照區에 비하여 改善되었으며 試驗後 土壤의 有機物含量은 有機物資源 施用으로 增加되었는데 그 效果는 生藁區와 堆肥區에서 顯著하였고 土性別로는 砂壤土보다 微砂質 埴壤土에서 높았다.
大豆와 大麥의 收量은 土壤의 孔隙率, 假比重, 硬度, 通氣性 및 耐水性 粒團 等과 높은 相關이 있었으며 有機物 施用으로 大豆 收量은 砂壤土에서 134-20%, 微砂質 埴壤土에서 33-67% 增收 되었고 大麥 收量은 砂壤土에서 1-13%, 微砂質 埴壤土에서는 4-20% 增收되었다.

A field experiment was carried out to find out thA field experiment was carried out to find out the effects of various organic matter resources on the improvement of soil physico-chemical properties and crop yields. Rice straw, compost and byproduct amino acid fermentation were applied to sandy loam and silty clay loam. Barley and soybean were cultivated under different fertilizer levels, conventional and integrated improvement, and several soil physico-chemical properties and crop growth were investigated.
Soil physical properties such as bulk density, porosity, hardness and air permeability were improved by organic resources application. Soil organic matter increased with application of rice straw, compost and byproduct amino acid fermentation at silty clay loam and sandy loam.
Yields of soybean and barley were highly correlated with porosity, bulk density, hardness, air permeability and water stable aggregates of the soils. Soybean yield was increased by 13-20% at sandy loam, 33-67% at silty clay loam respectively.
Barley yield was also increased by 1-13% at sandy loam, 4-20% at silty clay loam respectively.
