THE SYNERGY OF BIOCHAR, COMPOST AND BIOFERTILIZER FOR DEVELOPMENT OF SUSTAINABLE AGRICULTURE

Abstract

<p>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. 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. In this paper, more detail the effect of biochar on composting, its quality of compost and their effect on sorghum nursery will be discussed. </p><p><strong>Keywords</strong>: biochar, compost, plant growth promoting rhizobacteria, sorghum</p>
