| Title : | TESTING OF THE POTASSIUM CONTENT IN THE SOIL FOR THE PURPOSE OF PRESERVING BIODIVERSITY |
| Abstract : | The aim of this study was to determine the content of physiologically active potassium (K2O) in the soil in the territory covered by the work of the Agricultural Advisory and Expert Service of Smederevo (PSSS Smederevo). Research was carried out on three locations: Velika Plana, the City of Smederevo and Smederevska Palanka, for the purpose of ensuring the optimal use of mineral and organic fertilizers, to preserve soil resources. The paper presents the results of testing the content of physiologically active potassium – K2O. The territory of Velika Plana had most areas with harmful content, while the lowest content of K2O was recorded in the territory of Smederevska Palanka. The results indicate that the obtained values were greatly influenced by different types of soil on the examined plots, and an anthropogenic factor was also evident. All the plots from which soil samples were taken for analysis of potassium content were mapped, and based on the obtained results farmers were given advice on the necessary remedial measures and optimal use of organic and mineral fertilizers to improve agricultural production and preserve biodiversity. Mineral nutrition is extremely important for growth, development and reaching maximum yields of cultivated plants.foliar mass were higher in the PSB version (without fertilizers), and in the treatment with the use of P. polymyxa - with the use of N20P40 fertilizers. |
