Megjegyzések:In recent years intensive breeding methods have become increasingly dominant in animal husbandry. This is especially true in the poultry sector, which has undergone significant development in recent decades. Intensive systems produce large amounts of manure. Composting manure is an efficient method, requiring significant investments, but the decreasing and transforming organic matter content of soils is the reason why manure disposal is necessary. A compost tea made from compost or manure can be an effective method to nutrient replenishment without losses and environmental pollution. Compost tea is a concentrated, retarding liquid product that enhances soil life and is easier to apply to crop production technologies. The aim of this study was to produce a non-aerated compost tea from a mixture of deep-litter broiler and chicken manure treated with intensive composting. We examinated the effect of compost/water ratio (1:2.5-1:20), extraction temperature (20?C; 35?C; 50?C) and extraction time (24h, 48h, 72h) on the most important parameters of the prepared solutions (pH, electrical conductivity (mS/cm), nitrate, ammonium, phosphorus and potassium content). Based on our results, it can be stated that the compost used as a based material largely determines the content parameters of the solutions. Regarding the pH of the solutions, it can be said that by increasing the extraction time and temperature the pH decreases, which can be explained by the anoxic conditions in the solution. As the compost: water ratio increases, the eletrical conductivity of the solutions decreases. Regarding the nutrient content, the N-forms, P- and K content of the solutions increased significantly with increasing extraction time.
