Technologies and technical equipment for vermicompost production

Abstract

The production and use of biohumus is addressed to farmers who own livestock farms, and also to those who have vegetable farms: vegetables, orchards, greenhouses, wineries, etc. and have access to animal manure from other livestock farms. Composting is biological decomposition of biodegradable solid waste under controlled conditions in a state that is sufficiently stable to allow trouble-free storage and handling and that is satisfactorily matured for safe use in agriculture. Biohumus (earthworm compost) or earthworm is a pure natural microbiological organic fertilizer, having no preservatives in its composition, resulting from a mixture of manure and biological waste produced by earthworms. Due to its special composition (it has a large proportion of all the elements that plants need), it can be used in many fields of activity: horticulture, forestry, vegetable growing. When mineral fertilizers are not available or are too expensive, compost is the most important source of plant nutrients and soil condition. The use of the biohumus loosening plant aims to adjust the natural decomposition process, ensure good conditions for the composting process, especially air (oxygen), water, and a good composition of the material introduced into the piles, and monitor them for getting a quality product. Obtaining quality biohumus requires the application of a technology that establishes all the necessary steps to be completed. In this sense, within INMA, two installations necessary in the process of obtaining biohumus were substantiated, designed and realized: the biohumus loosening plant and the IPB biohumus production plant (vermicompost). This paper will present the results of the experiments performed with technical equipment for obtaining biohumus: the IAB biohumus loosening plant and the IPB biohumus production plant.
