Abstract A robust increase in crop production has lately been associated with the government incentives to agricultural producers to comply with production technologies, which include the use of synthetic fertilizers in the required quantities. Heavy crop yields remove nutrients from the soil, thus, necessitating supplementary fertilizing, which affects the soil, it being a developed agricultural ecosystem. The plant nutrient uptake from the soil becomes difficult, phytotoxic effect may occur. Certain measures for soil rehabilitation should then be taken, the most important of which is the use of green manure and minor nutrients as a basis of the symbiotic relationship between organic and mineral constituents of the soil.
