BACKGROUND: In this study, in order to verify the effects of supplemented organic amendment fertilizers recom-mended by the soil testing on cabbages, we used various amounts of organic amendment fertilizers. The amount of organic amendment fertilizers was decided by calculating each ratio of inorganic nitrogen, phosphorus, and potassium based on the recommended fertilizer composition. METHODS AND RESULTS: The cabbages subjected to treatments 1 and 2 showed similar or greater leaf colors (SPAD values), head heights, head widths, head weight, soil organic matter content, nitrate-nitrogen level, and con-ductivity after harvest, when compared with cabbages treat-ed with chemical fertilizers. The phosphorus and potassium fixation in the soil were higher in the plot where cabbages were treated with chemical fertilizers, and the nutrient use efficiency was greater in the plots with organic amendments and mineral addition.
CONCLUSION: The treatments 1 and 2 that were supple-mented with 180-200% of nitrogen, 100-130% of phos-phorus, and 185-250% of potassium in comparison to chemical fertilizers, applied by the inorganic ratios of ni-trogen, phosphorus, and potassium can be used as organic amendment fertilizers for cabbages.
