IMPROVEMENT OF THE COMPOSTING TECHNIQUE BY FORCED OXYGENATION DURING THE THERMOPHILIC PHASE

Agriculture

This subject is part of the framework of studies concerning the production of organic fertilizers, in particular compost. This is to improve the composting technique by adjusting a parameter which is the forced supply of oxygen in the compost heaps. Contribution made especially during the thermophilic phase to improve the living conditions of decomposing microorganisms, in particular their respiration. To do this, a simple manual forge blower was used. The method adopted is to vary the frequencies of forced addition of oxygen: every 2 days for heap n ° 3, every 4 days for heap n ° 2 and without addition for control heap n ° 1. After many follow-ups and interviews. The main result is the net acceleration of composting from 3 months to 1 month. 1 month for heap n ° 3 which underwent forced oxygenation every 2 days and 3 months for heap n ° 1 without additional input. The use of a simple manual blower enabled these results to be obtained, hence the interest of this study. Improving agricultural production requires the use of organic fertilizer available to farmers in addition to the quality of seeds and the availability of irrigation water.
