This study investigated the degradation of sulfonamide antibiotics (SAs) and microbial community changes in sludge-amended soil. In batch experiments, SA degradation was enhanced by addition of spent mushroom compost (SMC), SMC extract, and extract-containing microcapsule, with SMC showing higher SA degradation rate than the other additives in soil-sludge mixtures. In bioreactor experiments, th...

Agroindustrial wastes such as spent grain, cocoa husk, rice bran and sawdust, unamended and amended with cattle, poultry and goat droppings were studied as to their effect on growth, fruit yield and nutrient composition of tomato (Lycopersicum escutentum Mill) in two experiments. Analysis of the wastes showed varying nutrient composition with C:N values of 11.1, 12.5, 23.3 and 18.2 respectively...

A strain of the common mushroom Agaricus campestris was grown on a mixture of composted sawdust and CaCO(3). On incubation for 47 days, the organism produced 20.5 g of oxalic acid per 100 g of initial dry compost solids.

The REFERTIL project (FP7 contract no.: 289785) is developing safe and economical biochar quality criteria for EU policy support and proposal for possible inclusion of the biochar case into the EU FERTILIZER REGULATION revision (EC 2003/2003). The objective driven goal of this SME farmer targeted applied science and technology project is to reduce mineral fertilisers and chemicals use in agricu...

Effects of yard waste compost and maize (Zea mays) cultivar on population densities of plant-parasitic nematodes were examined in four experiments in north Florida. In one experiment, eight maize cultivars were evaluated; the other three experiments involved split-plot designs with compost treatments as main plots and maize cultivars as subplots. The three compost treatments used in these exper...

A two year field experiment was carried out to evaluate the effects of municipal waste compost (C), composted cattle manure (M), and nitrogen (N) on growth and composition of weeds in a corn field in Shiraz using a split-split plot design with 3 replicates. Visual inspection of the plots showed that the manure treatments neither introduced new weed species nor increased weed density more than t...
