The granulation of composite mixtures with potential use in agriculture as soil-conditioners gives good possibility for their mechanical distribution in the soil through different fertilizer-spreader machines. The granulated products ensure slower speed of the nutrients extraction in the soil solution and in the same time long-term presence in the soils and better utilization by the plants. This work presents the results from investigations on the granulation of composite mixtures for production of soil-conditioners. All used mixtures are based on ashes from burning wooden wastes and green lye -- wastes from pulp production. For some mixtures sulphuric acid was also used in order to compensate of alkaline reactions of other components and to obtain better properties of the soil-conditioner. The granulation process was realized by the method of press granulation, and the obtained granules were tested with a hydraulic press to determine the compressive strength of the products. The obtained values were compared with similar products. The moisture content of the granulated soil-conditioners were determined and compared also with similar type soil-conditioners.
