EKONOMSKI I EKOLOŠKI ASPEKTI UPOTREBE GOVEĐEG I KONJSKOG ĐUBRIVA U CILJU ENERGETSKE EFIKASNOSTI I PROIZVODNJE ORGANSKE HRANE / THE ECONOMIC ANG ECOLOGICAL ASPECTS OF USING CETTLE FACES TOWARD ENERGETIC EFFICIENCY AND ORGANIC FOOD PRODUCTION

Abstract

The cattle feces are mainly spread around fields and buried into land, regardless of whether it is necessary for the land or not. The land mainly does not need for this fertilizer due to its chemical structure. If the faces are buried into the land, it can be considered thrown away unnecessarily. For these faces we have a solution, how to use it more effective for energetic efficiency and as an organic fertilizer for food production. A huge amount of this fertilizer is wasted without any need or even use in an inappropriate manner, such as: spreading around grasslands, fertilizing already saturated arable lands. Base on the perceived and seemingly harmless agricultural operations we came to the conclusion that the huge amounts of the fertilizer are used unnecessarily. We are conduction the current research to reach the final goal, and it is the production of pellets from this natural fertilizer. During our research we came to the cognition that this pellet is more caloric than the fertilizer, with a greater energy power and more profitable comparing to the pellet made from wood, and the latter is less in quality and less efficient (about 26% more is needed). This pellet from the fertilizer can increase energetic efficiency, and feces can serve as an efficient fuel for heating. Also, the pellet can be used as the very quality organize fertilizer in the organic food production.
