The General objective of this research was to determine the optimal tea compost making process taking into accountratio dilution, time and temperature for increasethe availability of nutrients in soil, by analysing the effects of three different temperature and three different brewing times on thenutrient available concentration (nitrate (NO3-), Ammonium (NH4+), Potassium (K+), Phosphorus (PO43-)) and pH.Theresearchtook place in the laboratoryfacilities of the Institute of water and environmental managementof the University of Debrecen from February of 2020. Where Granulated poultry manure was obtained from a commercial supplier, by mixing this based material with distilled water, 3 different Compost tea solution were analysed.
