LONG-TERM NITROGEN AND PHOSPHORUS FERTILIZATION EFFECTS ON SOIL PROPERTIES

More and more attention is being paid to assessing the effect of long-term fertilization considering global warming to ensure sustainable soil fertility management. The aim of this study is to evaluate the soil properties under mineral fertilization in long-term experimental fields. These experiments were carried out in the experimental fields of SCDA Livada. In order to evaluate the effect of fertilization, with progressive doses of nitrogen and phosphorus, with 5 graduations, there were taken and analysed 75 soil samples. Following the statistical processing of the data obtained, it was observed that nitrogen and phosphorus fertilization significantly influenced soil properties. Based on these results it could be established the optimal doses of fertilizers that should be applied on soil in order to improve the quality of soil in terms of environmental protection. Also, these results contribute to contemporary knowledge regarding sustainable land use.
