“…Our observation of pH value remaining unchanged at about 8.0 from day 3 onward is in agreement with similar studies of aerobic co-composting degradation of organic compounds and neutral pH values (5.5-8.5) were found to be favored by aerobic microbial communities (Narihiro Lin et al 2012). Gaseous ammonia emission profile was recorded since gaseous ammonia represents odor released by microbial activity during the co-composting process as the mineralization of organic contaminants results in the formation of nitrogen (He et al 2018, Wang et al 2018. A gaseous ammonia profile can also represent the developmental stages of microorganisms within the co-composting (Kim et al 2017, He et al 2018.…”

In this study, gaseous ammonia reached a peak at 500 mg L -1 after 6 days and steadily dropped to 0 mg L -1 after 16 days, which is not statistically different from the temperature profile (p > 0.05).…”

Co-composting of organic wastes is globally recognized to be effective method to dispose two or more wastes at once and minimize drawbacks of composting such as gases emissions and nutrient reduction. In this study, pilotscale experiments were conducted to characterize the co-composting process of chicken manure with cow manure (CC), swine manure (CS), plant residues plus mushroom media (CRM), on emissions of greenhouse gas, and ammonia, compost quality, maturity and their correlations. The results showed that cumulative flux of carbon dioxide (CO 2), methane (CH 4), nitrous oxide (N 2 O) and ammonia (NH 3) widely ranged like 38,211-50,830, 172-417, 98-142 and 118-927 g kg dm −1 day −1 respectively. It indicated the importance of selection for co-composting material. The NH 3 emission was significantly increased by 4.3-7.9 times in CS and CRM, compared to OC and CC. Both of CS and CRM also showed longer thermophilic phase and later maturation were also observed in both treatments. Temperature was positively correlated with gases (P < 0.001) except CH 4 , and nitrogen content, C/N ratio and nitrate nitrogen significantly affected emission of carbon and nitrogen (P < 0.001). In conclusion, for chicken manure composting, sole chicken manure or combination with cow manure could be suitable composting method to improve compost quality and minimize gases losses.

“…The added organic matter in the form of plant residues, animal manures and raw oxidized compounds after a long-time decomposition process convert into humic substances and this process is named humification [1]. Compost is the intermediate form of decomposition which contains humic substances and partially decomposed organic matter [2]. The humic substances are present in almost all soils in small amounts, in the form of potassium humate, potassium fulvates and humins [3].…”

Humus is the stable form of added crop and animal residues. The organic matter after a long-term decomposition process converts into humic substances. The naturally occurring humus is present in less amount in soils of the arid and semi-arid regions. The addition of commercially available humic acid can, therefore, contribute to improving soil health and crop yields. The present study was conducted to evaluate the effect of potassium humate, applied through soil seed dressing, on cotton productivity and fiber quality attributes. Seed dressing with potassium humate was done at the rate of 0, 100, 150 and 200 mL kg−1 seed while in soil potassium humate was applied at the rate of 0, 10, 20 and 30 L ha−1. Results showed that the combined application of potassium humate by seed dressing and through soil application improved the soil properties, productivity and fiber quality traits of cotton. All levels of soil applied potassium humate (10, 20 and 30 L ha−1) performed better over seed dressing in terms of cotton productivity and fiber quality attributes. Among the soil application rates, 20 L ha−1 potassium humate proved better as compared to other rates (0, 10 and 30 L ha−1). Higher soil application of potassium humate (30 L ha−1) showed depressing effects on all the traits studied like the reduction of 12.4% and 6.6% in Ginning out turn and fiber length, respectively, at a seeding dressing of 200 mL kg−1. In conclusion, potassium humate seed dressing and soil application at the rate of 200 mL kg−1 and 20 L ha−1, respectively, is a better approach to improve cotton productivity. Soil potassium humate should not exceed a rate of 20 L ha−1 when the seed dressing of potassium is also practiced.
