Abstract
The mining soil on agriculture was caused by physical and chemical properties of soil damaged. The effect of mine was limited alternative crops. The ameliorant by organic waste was alternative for recovery of damage. The organic matter will decreased in the longer periode for growth by paddy soil. The organic matter was natural resource energy in the soil, which is very important for source of soil fertility. The content of organic matter less than 1% causes soil nutrients to become unavailable. Theoretically, to increase 1% of soil organic matter, it is necessary to add an absolute dry organic fertilizer of at least 20 tons / ha, even if the fertilizer is 100% organic component. Thus the provision of organic fertilizer does not automatically increase the soil organic matter content, considering the components of organic fertilizer is organic material that easily decay or remodel (manure, non-wood material for compost). Thus, the agricultural system can be sustainable if the content of soil organic matter is more than 2%. Organic material added to the soil significantly improves soil functions, the process of decomposition of organic matter leads to changes in the chemical composition of complex compounds into simple compounds. The utilization of organic wastes with pyrolysis (biochar) as a ameliorant of soil needs to be developed to improve soil fertility by improving C absorption and soil cation exchange capacity. The soil was content C more than 2% in the soil to sustainable agriculture. Key words: Biochar, Carbon, Decomposition, Exchangeable Cation Capacity, and Organic matter.
