Foliar
Stemma Leaf is a range of water-soluble microcrystalline foliar fertilizers, deriving from selected raw materials of the highest quality and purity, free from sodium, chlorides, carbonates and other insoluble or toxic substances.
Stemma Leaf formulas are tailored for foliar spraying and they are easily absorbed by plants: they nourish plants, meeting their precise needs during the entire crop cycle for maximum yields and top quality.
Moreover, every formula contains a high concentration of micronutrients in form of EDTA chelates that integrates the nutritional uptake and increases products effectiveness.
The full solubility allows for easy tank mixing and eliminates any risk of spray and blockage.
