Application of coconut biochar and organic materials to improve soil environmental

Inceptisol is a land which suitable for brick making, where the industry will take several meters of topsoil for raw material of brick industry. The loss of topsoil causes soil damage, while the topsoil is a source of nutrition for plant growth. The purpose of this study is to improve the soil environment because damage is caused by the brick industry. The application of the material used is biochar from coconut shell and cow manure with a dose of 0 tons per hectare, 10 tons per hectare, 15 tons per hectare, and 20 tons per hectare which is incubated in the topsoil for 0 months, 1 month, 2 month and 3 months. The best content of organic matter in the soil environment is around 2%. If it is lacking, then there must be added ingredients that contain enough C-organic and nutrients for good soil environmental conditions. The treatment of biochar and organic matter can improve the soil environment because it is a source of C and nutrients. Both of these materials function improve the physical and chemical properties of the soil such as cation exchange capacity (CEC) and soil pH. Changing characteristics will create a better soil environment so that soil nutrients will become more available for growth.
