Anaerobic digestion of agro-industrial and livestock waste generates considerable digestate volumes that are important sources nitrogen (N). However, on some occasions, the high concentrations N present in digestates may represent an obstacle to its use locally as fertilizer, since it can cause environmental impact (EC, 2000). This study analyzes efficiency gas-permeable membranes (GPM) recovery ammoniacal (NH4+) swine manure (SM, Control) three generated from anaerobic co-digestion mixtures...
ABSTRACT The objective of this study was to evaluate the adsorption phosphorus (P) and changes in concentrations organic inorganic forms P a Neossolo Quartzarênico (Typic Quartzipsamment) after 9 years successive cultivation with sugar cane without burning harvest. Therefore, two areas, one which planted native forest reference area, located municipality Paraipaba-CE, were selected. In each samples collected at depths 0−0.025, 0.025−0.05, 0.05−0.10, 0.10−0.20, 0.20−0.30 m, levels (Po) (Pi)...
Understanding the dynamics of organic matter and nutrients in pig manure submitted to anaerobic digestion is important assist decision-making regarding use biofertilizer agriculture. Accordingly, this study was carried out with objective evaluating changes matter, quantified as content carbon humic oxidizable fractions, inorganic forms phosphorus solid fraction manure, a function time reactors. Evaluations were after 7, 14, 21, 28, 35, 42, 49 days digestion, results compared raw manure....
ABSTRACT The permanence of sugarcane straw on the soil surface, in systems without pre-harvest burning practice, directly affects organic matter dynamics. objective this work was to evaluate changes total carbon (TOC), light (CLOM) and particulate (POC), their stocks a typic Quartzipsamment cultivated for nine years with crops, which were conducted Paraipaba, State Ceará, Brazil. Disturbed undisturbed samples collected at depths 0.0-0.025, 0.025-0.05, 0.05-0.10, 0.10-0.20 0.20-0.30 m, crop...
