Effect of long term addition of composts and poultry manure on soil quality of citrus orchards in Southern Italy

Compost Use in Organic Farming

“…The biochemical composition, such as contents of soluble C, cellulose, and lignin, appears to play a crucial role for mineralization Simard 1999, Mary et al 1996). For instance, compost organic N derived from vegetal tissues was much more resistant to mineralization than organic N derived from animal wastes (Canali et al 2003). Site-related factors include soil texture, pH, and climate.…”

Effect of sanitized and non-sanitized sewage sludge on soil microbial community and the physiology of pepper plants

“…Biolog® profiles have been used successfully to differentiate soil microbial communities associated with different substrates (Borrero et al 2004(Borrero et al , 2006 and to investigate the effects of soil management on its physiological diversity (Yang et al 2004;Canali et al 2004;Pérez-Piqueres et al 2006). The application of sewage sludge increased the rate of substrate utilization by the soil microbial community, therefore increasing the maximum level of colour development in the plates (AWCD at the plateau).…”

Biomass Digestion to Produce Organic Fertilizers: A Case-Study on Digested Livestock Manure

“…This last aspect represents an opportunity in relation to the need to close the nutrient cycles within the agricultural and natural ecosystems, particularly in specific systems underwent to a constant resources depletion, as those of Mediterranean area, where the C-sink loss represents one of the main causes of desertification [1], [2]. The composting process was yet identified as one of the promising answers to the need of soil organic matter conservation, such as the addition to the soil of different organic materials of different origins [3], but the anaerobic digestion could represent an effective further step able to guarantee the recycle of nutrients, coupled with an environmental-friendly energy production [4].…”
