Bio- gas Plant Feeding

Bio- gas Plant Feeding

Three main cycle components as in full agriculture system are crop  farming, bio - gas plant and animal products. Each provides direct economic benefit to agriculture.

Biogas  -  Provides  energy to household uses Provides  organic fertilizer to improve the soil or for merchandise.

Mixing:  the water and dung mixture should be in the ration of 1:1.Stirring should be done well  to help  in  mixing the manure with the water. Proper mixing determines the functionali ty of the digester and production of the gas. 

NB: During the rainy season, the right slurry density should be attained.

Animal excrement : daily quantity of dung    added must be sufficient, if too much or too little is added, very little or no gas will be  produced as the bacteria does not have sufficient time to break down the manure.
Temperature: the effective temperature for bacteria to grow is 37C 
 If higher or lower than the suggested the bacteria will not develop, decreasing gas production.  The dig ester should not be constructed under tree shades. 

PH  Balance: A pH between 7- 8.5 is optimal. If below the suggested pH, gas will not be
produced . Ensure that the substrate fed is not too acidic or too basic.
