Sažetak
Soil acidity in Croatia is one of the most important limiting factors for achieving high and stable yields. In eastern Croatia there is 27% of acid soils. Organic fertilizing is common measure which is usually applied together with liming. The aim of developing a computer model was to determine the cost- effectiveness of using solid stock manure from various aspects: the type of fertilizer, plot distance, the concentration of nitrogen and other nutrients in the manure, the market price of manure, and machinery costs (tractor, trailer, loader and plow). Manure use profitability depends on manure quality (N%), organic manure prices, trailer capacity, distance from economic yard to field plot and type of organic fertilizer. The contribution of the model to the decision support system in stock manure management is to precisely calculate profitability of manure use, which can affect the reduction of production costs.
