What is Biofertilizer?
Biofertilizers are obtained during the operation of biogas plants as a by-product and are widely in demand in agriculture. The process of obtaining biofertilizers occurs during fermentation without air access of organic waste, this makes it possible to obtain, in addition to biogas itself, environmentally friendly fertilizers. The use of biofertilizers makes it possible both to implement the process of organic farming and to increase yields when using biofertilizers in addition to conventional organic or mineral fertilizers. The use of biofertilizers allows not only to obtain environmentally friendly food, but also to improve the structure of the soil and increase its fertility.
Biofertilizers and Organic Fertilizers
Compared to conventional organic fertilizers, biofertilizers have a lot of advantages, including the absence of pathogenic microflora, weed seeds, an adaptation period, as well as the presence of active microflora, resistance to nutrient leaching, as well as the preservation and accumulation of nitrogen in fertile soils. Biofertilizers do not contain weed seeds, which are always present in organic fertilizers such as manure. In ordinary manure, pathogens of various animal and human diseases can be present, and biofertilizers, thanks to the technology of their production, are completely devoid of this drawback. Biofertilizers are several times better than conventional organic fertilizers in resisting their leaching from the soil, in addition, the use of biofertilizers avoids a lack of nitrogen due to the fact that these fertilizers contain much more of it than conventional organic fertilizers.
Biofertilizers and Mineral Fertilizers
Compared to mineral fertilizers, biofertilizers or biohumus also have different advantages. When using conventional mineral fertilizers, only part of them is absorbed by plants, and the rest accumulates in the soil or enters the human body along with food grown on the field treated with mineral fertilizers. Nitrates accumulated in food have a negative impact on human health. Biofertilizers, unlike mineral fertilizers, are almost completely absorbed by plants and do not accumulate nitrates, so the products grown in the fields that are processed with biofertilizers are much more useful than ordinary food. Another problem of using mineral fertilizers is soil mineralization, changes in its acidity, and much more. Even if they deviate from the norms for applying mineral fertilizers to the soil, they can significantly harm it. Biofertilizers do not have this drawback, they can be applied to the soil in any quantity without fear of overdose, since they are an environmentally friendly product and do not have a negative effect on the soil.
