“…According to Neklyudov et al (2006), all proper composting processes go through four stages: (1) mesophilic, (2) thermophilic, (3) cooling, finally ending with (4) compost maturation. The duration of each stage depends on the initial composition of the mixture, its water content, aeration and quantity and composition of microbial populations.…”

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

“…According to Mulligan (2005) [33], an increase in microbial activity would also increase the decomposition rate of readily degradable organic nitrogen, increase the amount of ammonia released and lead to a sharp increase in pH. The later phase of the secondary fermentation is associated with a reduction of readily degradable organic matter and a decline in the decomposition rate; at this point, the pH values decreased in all treatments and subsequently remained stable [30]. This decrease in pH could be related to an increase in nitrification experienced toward the end of the composting process, which acidifies the environment [34].…”

“…According to previous research, the optimal pH value for green waste compost is neutral [29], and it is closely related to microbial activity during composting [30]. A neutral pH enhances the water solubility of nutrients available for plant uptake, in particular that of P and many micronutrients [31].…”

Abstract:Following the Fukushima Daiichi Nuclear Power Plant (FDNPP) accident, the forests in the Fukushima area were highly contaminated with radiocesium ( 137 Cs and 134 Cs). Therefore, there is a need to develop strategies for remediation of the contaminated forests. We assessed changes in radioactive cesium ( 134 Cs and 137 Cs) contamination and nutrient status in composts derived from wood chip, bamboo leaf and bamboo powder using rice bran and wheat meal as sub-materials. Changes in soil properties and Komatsuna (Brassica rapa var. perviridis) growth were also investigated due the application of composts and initial materials at 0, 2.5, 5 and 10 kg·m −2 input levels. Mixing of sub-materials significantly reduced the concentration of radioactive Cs and improved compost quality. The effectiveness of three composts on soil quality improvement varied depending on their types and rates of applications. Amendments of bamboo leaf composts at 10 kg·m −2 resulted in the significantly highest soil inorganic N, available P and exchangeable K contents. Amendments of final composts also enhanced Komatsuna growth. Furthermore, radioactive Cs contaminations of the Komatsuna plants grown in these composts were below 0.1 Bq·kg −1 . This study may help to remediate the forests contaminated with radiocesium in the Fukushima area while improving the soil organic matter content to enhance soil sustainability.
