Survey on manure management and evaluation of efficacy of indigenous microorganism in manure decomposition
(Sokoine University of Agriculture, 2008) Msangi, Paulo Henry Silas
Agriculture provides rural and urban dwellers with extra income, food and offer employment to family members. However, intensive livestock raising is associated with concentration of manure a source of bad odour and threat to surface and ground water. Proper utilization of manure also requires adequate knowledge on handling, storage and application. Two studies were conducted; to survey on manure management at Mvomero district and to evaluate the efficacy of native bacteria (Indigenous Microorganism) in manure management. In study one a structured questionnaire, focus group discussion and physical observation were used. Thirty-two dairy formers were purposively selected and interviewed. Data collected were analyzed using SPSS (11.5) computer software. Study two was an experiment used to evaluate efficacy of different substrate sources for culturing indigenous microorganism (IMO), used on animal manure decomposition. To activate the native bacteria, K kg of three protein sources that are Moringa leaves, Leucaena leaves and Fishmeal and a combination of one kg of two energy sources (Cassava and Molasses) were used. Samples of cattle and pig manure were collected and subjected into sensory test At the same time fifty samples of cattle manure were collected and sent to laboratory for determination of N, P, K and organic carbon. Data obtained were statistically analyzed using SAS (2004) computer software. Survey result showed that, there was underutilization of manure in the study area, due to a number of constraints. In study two, results showed that, there was no significant P< 0.05% difference on the quality of manure produced after being treated with IMO cultured using different substrate sources. Sensory test indicated that, there is significant difference at 0.05% and 0.01% on smell (odour emission) while there was no significant difference on texture. On the basis of these results, the use of IMO is recommended to improve manure decomposition and reduction of bad odour emission. Furthermore, farmers should be educated on manure management to improve crop productivity.
