| Sumario: | Chicken production wastes, principally
poultry manure (layers) and litter
(from chickens for fattening), may impact
negatively on the environment, contributing to
soil, water and air pollution. Aerobic stabilization
through composting is an alternative to reduce
contamination. This study aims to evaluate
the composting process in two mixtures with
different percentages of poultry manure of
laying chickens and broiler poultry litter.
Two mixtures were composted containing 81%
and 70% of poultry wastes for 16 weeks. The
analytical parameters were: temperature (T°),
pH, electrical conductivity (EC), humidity (H),
cationic exchange capacity (CEC), total
organic carbon (TOC), amonium (NH4+),
nitrate (NO3- ), total nitrogen (TN), soluble
carbon soluble (SC) were determined in
each treatment. The final compost A and
B characteristics were 7,1 - 6,8, CE 3,3 -
2,9 (mS.cm-1), COT 14,8 - 17,9%, NT 0.97 -
0.88%, NH4+ 501 - 144,9 mg kg-1, NO3
- 552,3 -543,0 mg kg-1 respectively. The composting
process may be a tool to stabilize poultry
wastes, minimizing its environmental damage. |
