Support for growth, maturity and optimal quality of food crops is essential to their adequate hatred. In many businesses involved in crop and animal production it is common to apply compost to mineral grasslands Organic fertilizer is an undeniable basis for rational farming. High farm fertilizers support soil fertility and have other positive effects (Samuil et al., 2009). Through their systematic use, essential nutrients are returned to the soil and additional mineral fertilizers are less needed in grassy areas. The difference is that organic fertilizers can be taken directly from plants in contrast to organic fertilizers, which must be released by microbial metabolism to make most of them available to plants.Problem statement: There is an advantage to organic fertilizer lying in fact, that its use has a positive effect on the carbon content of organic. Microorganisms play an important role in the formation of living things, in the restoration of bicycle nutrients and other chemical reactions in the soil. That follows; there should be a long-term effect on the organic fertilizer application system, however, which could be limited to grassroots areas. In addition, the addition of an object from a variety of sources may differ from the effects of the soil organic matter and biological activity. Usually, computers decompose slightly in the ground. The aim of our study was to investigate the impact of long-term use of biodiversity and organic fertilizers on the chemical environment of grassland soils. The purpose of this study was to study changes in the chemical properties of perennial grasses after complete use and consolidation of the environment. A small long-term case was established in 2004 in the Rototín area. There is an advantage to organic fertilizers lying in fact, that their use can have a positive impact on the carbon content of the earth (Gonet and Debska, 2006). Microorganisms, e.g. Bacteria, fungi, actinomycetes and microalgae, play a vital role in biodiversity, cycling, and chemical reactions in the soil .Methodology and Theoretical Oriental: A small, lengthy trial was started in 2004 in the Rototín area of the Czech Republic. In 2004-2013, the experimental work was performed on fertilizers and lubricants, with both 0.9, 1.4 and 2.0 (LU) / ha stocks (corresponding to 54, 84, and 120 kg N / ha), and control without fertilizer. The sites were cut 2-4 times a year depending on the given amount of fertilizer. By 2013 to 2006, general management had been eliminated and grasslands could not be fertilized.Findings: Chemical soil components such as carbon organic whole, Kjeldahl complete nitrogen, humic acid and fluvic acid were determined. Based on data on soil chemical boundaries from the two years under investigation (2011 and 2016) our results suggested a significant effect on grass management (type of organic fertilizer) and an important annual result.Conclusion and significance: Our findings show that the addition of substances from various sources differs from the effects of organic matter and other chemical components of the soil, including the ratio of humic acid and fluvic acid.
