Cassava peel based substrate formulations as an alternative substrate were used to grow mushrooms. The effect of two compost heights, three composting periods on the mycelia growth, physical characteristics, yield, and nutritional qualities of Pleurotus ostreatus (Jacq. ex Fr.) Kummer was studied. Mean mycelia growth of 16.2 cm after a period of seven (7) weeks was the best for 1.5 m compost he...

The concentrations of some widely used pharmaceuticals, namely fluoroquinolones (ciprofloxacin C H FN O , norfloxacin C H FN O and ofloxacin C H FN O ) and sulfonamides (sulfadimethoxine C H N O S 17 18 3 3 16 18 3 3 18 20 3 4 12 14 4 4 and sulfamethoxazole C H N O S ) were determined in urban sewage sludge utilized for making compost. The 10 11 3 3 levels of degradation of these pharmaceutical...

Utilisation of palm oil mill wastes to make soil conditioner through anaerobic co-composting is feasible and has the potential to maintain the natural resources, and to reduce the impact on environmental quality in the future. Co-composting process uses pressed-shredded-grinded empty fruit bunch (EFB) with activated sludge (AS) from the pond system of a palm oil mill as a suitable option for or...

Compost, poultry litter, IPM Lab Biopesticide and BAU-Biofungicide, either alone or in combinations, were assessed for their effect in controlling early blight disease, and on growth and yield parameters of tomato. The lowest early blight incidence and severity were recorded in T13 (compost tea + poultry litter extract + BAU-Bio-fungicide) followed by T12 (compost tea + poultry litter extract +...

Two compost formulations based on oat straw (Avena sativa) and brachiaria (Brachiaria sp.) were tested for the cultivation of three Agaricus bisporus strains (ABI-07/06, ABI-05/03, and PB-1). The experimental design was a 2 × 3 factorial scheme (composts × strains) with 6 treatments and 8 repetitions (boxes containing 12 kg of compost). The chemical characterization of the compost (humidity, or...

This study investigated the dynamics of Aspergillus fumigatus azole-resistant phenotypes in two compost heaps with contrasting azole exposures: azole free and azole exposed. After heat shock, to which sexual but not asexual spores are highly resistant, the azole-free compost yielded 98% (49/50) wild-type and 2% (1/50) azole-resistant isolates, whereas the azole-containing compost yielded 9% (4/...

A composting product of marine animal resources has been used as a fertilizer and a soil conditioner in Japan. This compost was produced by a repeated fed-batch fermentation system with three successive aerobic bioreactors. Composting temperature reached about 75 degrees C without heating. The bacterial diversity in this compost was investigated by denaturing gradient gel electrophoresis (DGGE)...

The aim of this study was to investigate the composting of separated pig manure solids with or without a variety of bulking agents at a low initial C/N ratio (12.5-23.3). Compost stability was investigated using an oxygen uptake rate (OUR) test and compost maturity was investigated using a germination index test. All treatments showed typical patterns of compost temperature. Temperatures above ...

are enhanced. Sugarcane germination can also be promoted by increasing soil Ca (Mohandas et al., 1983). Louisiana sugarcane (Saccharum spp.) is produced mainly on For some crops, gypsum is effective in reducing the heavy-textured soils that offer less than ideal conditions for growth and function of the root system. Cultural practices that improve the incidence of soil-borne diseases (Kao and K...
