Metrop concentrate liquid fertilizer is a special type of liquid manure. The company has many years of experience in the field, so they have developed an approach that separates them from other fertiliser producers. They improve their products by conducting deep sap analysis on a regular basis, every fifteen days during the flowering and growth cycle of the plant. They also conduct research in two laboratories that are devoted to liquid fertilizers and vegetation stimulators. In addition, Metrop products contain no heavy metals, which means that they are completely safe for use.
