Effect of Lignin Biochar Application on Kimchi Cabbage Cultivation

Abstract

This study evaluated the effect of lignin biochar on Kimchi cabbage cultivation in an upland field. Each of the inorganic fertilizers (IF, applied at 32-7.8-19.8 kg/ 10a=N-P-K), lignin biochar (LBC, applied at 1,000 kg/ 10a), improved LBC (LBC+N, applied at 1,000 kg/10a), and LBC+IF treatments areas were separated by a con-trol (Cn) treatment area. The fresh weight of Kimchi cabbage increased in the order LBC+N > IF > LBC+IF > Cn > LBC treatments, and the length and width of the leaf were ranged from 20.8-25.7 and 13.7-15.8 cm/ plant in all treatments. After Kimchi cabbage harvesting in the LBC+N treatment, soil quality improved bulk density, pH, OM, TN, and Av-P 2 O 5 than those other treatments. In addition, the total N 2 O flux in LBC+N was lower than in IF treatments. Therefore, improved lignin biochar application effectively improves Kimchi cabbage cultivation and can benefit the agricultural environment.
