As an important pawn in intensive agriculture, fertilizers are identified, whether organic or mineral, whit their specific effects on the physical properties of the soil, which is what this study aims to do. The application of mineral fertilizers has a quick and predictable effect, but with higher acquisition and application costs. At the same time, for a long term, they have side effects, such as decreased soil fertility and soil toxicity. Organic fertilizers improve soil structure, texture and water retention capacity, leading to more optimal development conditions for the plant root. Also, organic fertilizers are a much more affordable option for farmers, but somehow more difficult to handle and manage. Therefore, the work will track the value of some important soil physical properties such as soil reaction, humus content, bulk density, degree of settling and porosity, in relation to different doses of organic, mineral and organo-mineral fertilizer applied in an experimental sugar beet field in Covasna County.
