As I have highlighted bocashi is a Japanese word meaning "fermented organic matter", a translation of this word into English (referring to compost). It is fermented organic fertilizer, traditionally, for the preparation of Bocashi, Japanese farmers use organic matter such as rice semolina, soybean cake, fish meal and forest soil as inoculant for microorganisms.
▶ As already mentioned, the use of bocashi-type organic fertilizers to maintain and improve the availability of nutrients in soils and maintain higher crop yields has been known since ancient times. In this sense, the range of organic fertilizers includes manures, crop residues, industrial organic wastes, sewage and organic sediments.

Therefore, bocashi organic fertilizers are of physical and chemical variety. In this sense, bocashi organic fertilizers are all those residues of animal and vegetable origin from which plants can obtain significant amounts of nutrients, the soil, with the decomposition of these fertilizers, is enriched with organic carbon and improves its physical, chemical and biological characteristics.
From this perspective, it is proposed that bocashi organic fertilizer is essential to achieve accelerated crop yields. In this way, organic fertilizers, due to their own characteristics, are considered humus producers and enrich the soil with this component, modifying some of the properties and characteristics of the soil, such as its reaction to pH, variable loads, availability of phosphorus, calcium, magnesium, potassium, among others.
Likewise, it allows to make more own for the good development and yields of crops, in fact, one of the main Bocashi type carbon usually improves production levels in units highly dependent on synthetic fertilizers.
