Biochar and LMO (Local Micro Organism) VCO liquid waste Improves The Quality of Soil Chemical Properties and Kale Production

Abstract

Kale plant has many health benefits, especially can help cure glaucoma cancer. When planted on inceptisol soil the yield is not good, so it needs to be improved the quality of the soil. Many have studied Biochar to improve soil quality, but no one has yet combined Biochar with Local Micro Organisms from VCO (Virgin Coconut Oil) liquid waste. So the purpose of this study is to study the improvement of the chemical quality of inceptisol soil for kale plant cultivation, using Biochar with Local Micro Organisms from VCO (Virgin Coconut Oil) liquid waste. The materials used are Biochar and MOL from VCO liquid waste, which has previously been added cow dung on the land.  The method of making Biochar is by pyrolytic combustion. Cultivation in Kale plants using experimental methods using two-factor GRD namely Biochar and Micro Organisms Local (MOL) VCO liquid waste. Biochar with 3 levels and MOL 4 levels. The content of N, P, K and pH, its analyzed before and after the planting age of 4 weeks. Observed its growth by paying attention to the height of the plant, the number of leaves, the length of the leaves, the width of the leaves and the weight of fresh Kale per plant after harvesting. It turns out that the pH of the soil rose from 4.5 to 7.0; N content from 0.2% to 0.54%; P from 0.021% rose to 0.056% and K from 0.2 me / 100 gr rose to 0.54 me / 100 gr. His RAK analysis was analyzed with the SPSS program and the results differed markedly. Improving the quality of inceptisol soil, in the future can increase kale vegetable production.
