By-products of the agri-food sector are increasingly employed in production new organic preparations, with biofertilizer and biostimulating functions, thus reducing consumption non-renewable resources turning chains towards circular economy sustainability. Two composts were produced solid digestate (85%) as a common component different sources recyclable materials (15%): vine pruning wood (comp...

Cherry tomato cultivation in protected environments ensures production the off-season, reaching yields up to 100 t ha-1 with 150 days of cultivation. Fertilization organic composts can influence components cherry tomato. From this perspective, study aimed evaluate different doses and composts, based on their nitrogen contents, The experiment was conducted municipality Boa Vista - RR, at Agrotec...

Livestock waste composts with minimum inorganic fertilizer as a soil amendment in low-input intensive farming are a feasible agricultural practice to improve soil fertility and productivity and to mitigate soil degradation. The key benefits of the practice rely on the activities of soil microorganisms. However, the role of different livestock composts [composted cattle manure (CCM) vs. composte...

Nitrogen and carbon mineralization rates of 19 manure and compost samples were determined in 1996, with an additional 12 samples evaluated in 1997. These organic amendments were mixed with a soil : sand blend at 2% by dry weight and the amended blends were incubated at constant moisture for 12 (1996) or 24 weeks (1997) at 25 °C. Net N mineralization was measured at 4(1996) or 8-week (1997) inte...
