One of the important factors affecting nutrient uptake by the root system of the plants includes soil reaction. Increased soil acidity may adversely affect the use of biogenic nutrients, such as phosphorus, potassium, calcium, magnesium, sulphur and molybdenum. In soil, nutrients are immobilized to insoluble forms. Although their amount in soil may be sufficient, the plants cannot obtain the optimal quantities, causing a decrease in the yield or production quality. On the other hand, in the metabolism of plants, a...
