Abstract
Composting is an alternative way for practicing site-specific and environmental friendly plant nutrient supply. Our aim was to study the effect of different composts on plant and soil system. Pot experiment with acidic sandy soil blended with three composts in five (0%, 5%, 10%, 25% and 50%) proportion was set up. Our experimental plant was perennial ryegrass (Lolium perenne L.). After the harvest of ryegrass we measured the fresh and dry weight of harvested plants, the P-, K-, Mg-contents, and the pH of soils.The three composts had different effect on dry weight production and on nutrient-supply of soil. We established that one of the compost had significantly larger effect on the dry weight of ryegrass compared to the others. In this study we proved that favourable compost/soil proportion is different in the case of different composts.

We found the highest positive effect in the case of 1st compost
Summary
The location of waste emitted in increasing volume is one of the most important environmental problems of sustainable development. One of the solutions for this problem is composting. Beyond this the fertilization of horticultural crops with the composted waste materials, containing a large amount of organic matter content, is one of the alternative, environmental friendly plant nutrient supply practices. The reason of that we chose the more accurate cognition of compost utilization is to do more effective and site-specific the nutrient supply with composts. Our aim was to study and evaluate the relations between the dry matter productions of plant, the compost:soil ration and the nutrient content of soil
