Due to the intensive fertilization of the soils, salinity is formed and thus yield losses occur. Fertilizers start to accumulate in the soil with fertilization and cause salinity. Over time, these soils become barren and inefficient. Especially in tomatoes, fruits remain small and other plants cause growth disorders. Flowering and fruit growth slows. Key Salinity relieves stressed plant roots due to intensive fertilization and removes the sodium that accumulates in the soil and causes salinity. Removes the hardness of water. Irrigation water and soil by regulating the pH of the plant has the property of relaxing and facilitates the uptake of macro and micro elements. Due to salinity and high pH, yield losses occur in all vegetables and fruit trees. With a regular use of Key Salinity, this loss is reduced to a minimum.
