Compost stability and maturity are important parameters of compost quality. To date, nearly all compost characterization has been performed using samples freshly collected because sample storage can affect compost stability and maturity evaluation. However, sample preservation is sometimes necessary, especially for scientific research purposes. There is little information available on the effec...

The fungus Agaricus bisporus is commercially grown for the production of edible mushrooms. This cultivation occurs on compost, but not all of this substrate is consumed by the fungus. To determine why certain fractions remain unused, carbohydrate degrading enzymes, water-extracted from mushroom-grown compost at different stages of mycelium growth and fruiting body formation, were analyzed for t...

The effect of successive applications of urban compost (up te 150 and 400 t ha-1 during eight years) en the status ef phosphorus in a calcareous soíl (20%) was testad in a greenhouse experimento An 6-15-15 complex fertiliser was also applied for comparison. Five years of ryegrass and three of horticultural plants (tomate and eggplant) were successively cropped during the experimento Increases o...

Compost teas (CTs) are organic solutions that constitute an interesting option for sustainable agriculture. Those come from garden waste have been applied in vitro and vivo on pepper plants to determine its suppressive effect against both Phytophthora capsici Rhizoctonia solani. The studied CT showed relevant content NO3?, K2O, humic acids, microorganisms such as aerobic bacteria, N-fixing acti...

The distribution of ammonia-oxidizing archaea (AOA) and bacteria (AOB) in cattle, swine, and chicken manure compost was analyzed. PCR-denaturing gradient gel electrophoresis (DGGE) showed that a Candidatus Nitrososphaera gargensis-like sequence dominated in cattle manure compost, while few AOA were detected in other composts. In the case of AOB, Nitrosomonas-like sequences were detected with hi...
