Integrating aeration and rotation processes to accelerate composting of agricultural residues

Management of antibiotic residues from agricultural sources: use of composting to reduce chlortetracycline residues in beef manure from treated animals.

Chlortetracycline (CTC) is one of only ten antibiotics licensed in the U.S.A. for use as growth promoters for livestock. The widespread use and persistence of CTC may contribute in development of antibiotic-resistant bacteria. The objective of this study was to determine the effect of composting on the fate of CTC residues found in manure from medicated animals. The effect of CTC residues on co...

Composting Agricultural and Industrial Wastes

Effect of aeration rate on composting of penicillin mycelial dreg.

Pilot scale experiments with forced aeration were conducted to estimate effects of aeration rates on the performance of composting penicillin mycelial dreg using sewage sludge as inoculation. Three aeration rates of 0.15, 0.50 and 0.90L/(min·kg) organic matter (OM) were examined. The principal physicochemical parameters were monitored during the 32day composting period. Results showed that the ...

Windrow composting of agricultural and municipal wastes

Kuhlman, L.R., 1990. Window composting of agricultural and municipal wastes. Eur. Symp. on Integrated Resource Recovery from Municipal Solid Wastes. Resour. Conserv. Recycl., 4: 1 5 1 160. Many wastes are produced from agricultural and municipal facilities that are not suitable for direct land application. Composting these wastes converts them to a humus-containing organic material advantageous...

Effect of sulfonylurea herbicides residues on growth and yield of sunflower in rotation with wheat

To evaluate the effect of residue of sulfonylurea herbicides and  wheat residues on the growth and yield of sunflower, a split factorial experiment was conducted based on a randomized complete block design (RCBD) with four replications at the College of Agriculture, Shiraz University, Shiraz, Iran. The treatments included with and without wheat residues from the tested farm as the main plots, a...
