Abstract

This study was carried out to evaluate nitrogen availability of applied fertilizer and to investigate yield and growth of Korean kimchi cabbage as affected by amount of fertilizer and soil fertility in organic farming applied various fertilizers in rainshelter. The head weight of Korean kimchi cabbage cultured in infertile soil (sand loam) with no amendments was very low. and that in fertile soil (clay loam) was higher than in infertile soil (sand loam). The head weight of Korean kimchi cabbage as affected by amount of fertilizer was more variable in infertile soil (sand loam) than in fertile soil (clay loam). Nitrogen availability of applied fertilizer by Korean kimchi cabbage was lower in fertile soil (clay loam) than in infertile soil (sand loam) and the lower that was, the more fertilizer applied. By application of poultry manure compost 20Mg ha-1 and natural mineral materials such as guano, phosphate rock, and potassium magnesium rock equal to amount of fertilizer recommended in conventional farming, the yield of Korean kimchi cabbage in infertile soil (sand loam) with 1% organic matter came up to 90% of the yield in fertile soil (clay loam) with 6% organic matter. Therefore natural mineral materials such as guano for N source, phosphate rock for P source, and potassium magnesium rock for K source may be able to use as environmental-friendly fertilizers in organic Korean kimchi cabbage production in highland.
