Sažetak
The fertilizator calculation starts with crop selection, the planned yield and maximal yield (the yield possible with the application of the best agrotechnology in the same or similar condition, regulary 20-40 % higher than planned). The nexrt step is input of data as follows: pH (KCl), humus (%), AL-extracted phosphorus and potassium (mg/100 g soil), soil texture (light, medium, heavy) and manure dose. Ba every change of the particular parameter, the calculator automatically estimates the fertilization requirement at the passing at the other field or by the activation of the field "calculate". The click on the key "reset data" erase the content of all fields for the new data import. The result of the calculation is the recommendation of N, P and K doses for each crop with the amount and distribution of commercially available mineral fertilizers for primary fertilization and top dressing. The calculated amount of NPK is the compromise between the phosphorus and potassium requirements, meanwhile the nitrogen fertilization and distribution are recommended by crop needs and soil texture.
