“…According to Chien (1979), a lot of CO 2 is produced during composting which after combining with water forms carbonic acids and also helps in the reduction of pH of the materials being composted. This decreased pH would ultimately help solubilize the fixed P in the form of RP or in the soil (Bangar et al, 1989).…”

To cite this paper: Ditta, A., M. Arshad, Z.A. Zahir and A. Jamil, 2015. AbstractOptimum impregnation ratio of rock phosphate (RP) and compost in RP-enriched organic fertilizer, its time and rate of application to the crop plants affect the availability of nutrients through the process of mineralization and immobilization. A series of pot and field experiments were conducted to investigate the comparative efficacy of RP-enriched organic fertilizer vs. mineral phosphatic fertilizer on growth, yield and nodulation of lentil. Optimum impregnation ratio of RP and compost and the time of application to improve growth, nodulation and yield of lentil were investigated under wire house conditions. The impregnation ratio of 50:50 RP and compost and time of application of seven days before sowing resulted in the maximum nodulation, growth and yield parameters compared to the other impregnation ratios and the times of application. Optimized impregnation ratio and time of application were further investigated for optimum rate of application under field conditions to enhance nodulation, growth and yield of lentil in comparison with recommended mineral phosphatic fertilizer. The application of RP-enriched organic fertilizer @ 1000 kg ha -1 showed an increase of 35.5, 27 and 6% in number of nodules, fresh weight of nodules, and grain yield compared to chemical phosphatic fertilizer, respectively. Similarly, significant increase in P contents of straw and grain was also observed with the application of RP-enriched organic fertilizer @ 1000 kg ha -1 compared to chemical phosphatic fertilizer. However, the effect of the application of 800 and 1000 kg ha -1 was statistically non-significant for most of the parameters studied. The results suggested that RP-enriched organic fertilizer with optimum impregnation ratio of RP and compost, time of application and rate of application had a pronounced effect on nodulation, growth and yield of lentil as compared to recommended chemical phosphatic fertilizer.

“…To overcome this problem, pyrite minerals have been tested as Nconserving additives. Using 1% urea N, 10 or 20% RP and 10% pyrite as conservative, Banger et al (1989) made N and P enriched compost containing higher level of total N than usual and substantially high content of total P in the compost. Addition of NH 4 NO 3 and NH 4 Cl to the fermentation medium was found to improve the macerating potentiality due to an increase in enzyme levels (Hamdy, 2005).…”

Largely accessible organic wastes can be turned into valuable compost product for raising crops organically on one hand, and get them disposed off safely at the other end. Straight use of organic wastes has tribulations like transportation and handling, wider C:N ratio, high application rates, nutrient overloading, weed seeds, pathogens, and metal toxicities. Composting bestows a tactic for coping high volumes of organic wastes in environmentally sound and desirable manners. Composted materials are remarkably regarded for their ability to improve soil health and plant growth, and suppress pathogens and plant diseases. Currently several composting systems have become available; ranging from a crude and slow windrows method, to the most speedy and computer monitored in-vessel system. Scientific investigations of this biological cum chemical process have reached to molecular level. Value addition of compost through beneficial microorganisms, mineral materials and fertilisers is also being considered. The nature and composition of materials put into composting is imperative for its quality rationale. On the whole, principles and processes governing composting are not so straightforward that ordinary enterprises could develop efficient composting facilities for the treatment of organic wastes. In this scenario, accessibility of comprehensive information to the scientific community as well as environmental protection agencies is imperative. This review article brings together the current information necessary for effective composting of organic wastes from different origins with diversified characteristics under various situations. It also covers the schematic description of well known composting systems, and various factors controlling the process.

“…Immobilization of N on direct incorporation of rice straw in soil is caused due to its wide C:N ratio and therefore, composting is a preferred method of straw disposal (Banger et al 1989, Goyal et al 2005. In order to hasten decomposition the initial C:N ratio of the straw can be narrowed down by addition of fertilizer nitrogen or nitrogen-rich organic wastes such as poultry manure or sewage sludge low in heavy metals and hazardous organic compounds (Ranalli et al 2001, Iranzo et al 2004).…”

Enrichment of compost raw material with rock phosphate before composting to increase the P content is a viable option to meet P requirement of crops (Banger et al 1989, Manna and Ganguli 1998, Biswas and Narayanasamy 2002. Organic acids and humic substances produced during decomposition are mainly involved in the P solubilization process (Kapoor et al 1989, Singh andAmberger 1990).…”

The production of organic acids and changes during decomposition of rice straw amended with tricalcium phosphate (TCP) and Udaipur rock phosphate (URP) were studied under laboratory conditions. The organic C content of rice straw decreased and total N increased with time, resulting in a decrease in C:N ratio as the decomposition progressed. The pH decreased to acidic range in all the treatments on day 15, but became alkaline again later on. Soluble P increased at 15 days after incubation, declined later during decomposition, and was highest in the treatments containing TCP and Aspergillus awamori inoculation. Citric, oxalic, formic and maleic acids were detected during decomposition of rice straw and maximum amounts were present on day 15. Citric and oxalic acids were responsible mainly for P solubilization from TCP and URP; generally, citric acid was the most effective in P solubilization.
