| Tartalmi kivonat: | The paper presents the results regarding the effect of different NPK fertilization doses on change, during three years of agrochemical soil parameters after tomato mineral fertilization. The following agrochemical indicators were analyzed: pH, humus, total nitrogen, mobile phosphorus and mobile potassium content. The experience was done in a cambric cernosium soil, with low acidity reaction, very good content in nitrogen, phosphorus and potassium and the high natural fertility potential favorable vegetables cultivation in Romanian Western Plain area. The experimental field is located in temperate climatic area, characterized by Koppen classification in the formula Cfbx. The study was performed on control soil samples (without fertilizers) and soil samples after differentiated NPK fertilization in variable dozes: N30P30K30, N45P45K45, N60P60K60 and N120P60K60. Tomato fertilization with mineral fertilizer determines, in time, significant modifications of agrochemical soil parameters. To preserve the soil quality must find the optimum dose of NPK fertilizer in tomato crop fertilization. |
