The Synergy of Biochar, Compost and Biofertilizer for Development of Sustainable Agriculture

Abstract

Abstract. To initiate the decomposition process need decomposer inoculants and an easily available nutrient as C sources (sugar, carbohydrate) and N sources (protein, N inorganic fertilizer). Fresh organic materials are suitable sources for all nutrient needed. Cattle manure or Urea is important N sources for the initiation of composting process. Charcoal -Ash is referring the entire remnants of a wood/bamboo burning fire. In reality, what remains after a typical fire in a bamboo or wood burning stove or fireplace is both ash and charcoal. Both ash and charcoal can offer tremendous benefits to the compost and garden soil. In order to enhance the decomposition processes and its quality of compost, addition of other valuable materials are necessary. Therefore preliminary study of synergy of biochar for composting was conducted. The field experiments were conducted in Terantang village, Sampit-Central Kalimantan and laboratory analysis were conducted in the laboratory of ecology and physiology of microorganisms, Reserach Center for Biology Cibinong. Composting experiments were done by using compostion of brackens (Pteridium aquilinum) and rattan wastes : bamboo charcoal : cattle dung (80:3:17; by volume). Use a shovel to turn the compost after reach maximum temperature and start to cooling. After 3 months incubation, the parameters measured were the number of plant growth promoting rhizobacteria after composting and the C/N ratio of the compost. Those all parameters were compared with natural composting (control). The significant higher number of PGPR and better quality of final compost of treated biochar were observed

“…Biochar improves composting processes, as well as the biochemical properties of compost, by increasing the number of plant growth-promoting rhizobacteria (PGPR), which solubilize phosphate, produce indoleacetic acid (IAA) and degrade protein and cellulose. Biochar can also synergize the use of biofertilizers for promoting sustainable agriculture (Antonius et al 2015).…”
