Our institute has a Soil and Plant Laboratory, and makes appropriate fertilization recommendations by making soil and leaf analyses. We analyze soil samples for lime, texture, pH, salt, organic matter, potassium, phosphorus, iron, zinc, copper, manganese, magnesium and calcium. In plant samples, on the other hand, analysis of total nitrogen, potassium, phosphorus, iron, zinc, copper, manganese, magnesium and calcium are performed. Microelements are detected with the ICP method.
