  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.

  Satisfaction of the increasing needs of humanity causes large environmental load. To provide a livable environment for future generations we have to satisfy our needs with the use of sustainable management. This is one of the biggest challenges of nowadays.
  The amount of wastes emitted in increasing volume can be decreased by the recycling of them. The disposal of waste materials formed in the public spaces of cities and during the processing of agricultural row materials and by-products in landfills is inconceivable, so they must be recycled.
  These materials mostly with organic compounds could be the primary substrates of composts. Completed with suitable additives, and applied appropriate treating technology, composts are capable to supply horticultural plants with nutrients. Composting wastes and byproducts not just decreases the amounts of deposited waste materials, but increases the nutrient (macro- and micronutrients) content of soils, so this is an  environmentally friendly and alternative way of nutrient management of plants.
