Zeizamin 40 is a water-soluble organic fertiliser based on free amino acids. As a biostimulant, it stimulates plant growth and development, acts as a natural complexing agent and improves nutrient uptake from both the soil and foliar applications with trace elements. It can also enhance the crop’s resistance to drought, salt damage, frost damage, sunburn, pests, and diseases. Moreover, it is widely used as a foliar fertiliser in combination with other water-soluble fertilisers to improve their efficiency.
