Water-soluble fertilizer consists of trace element iron 300 g / kg and specially prepared plant extract. Mechanism of action: Plants need iron to produce chlorophyll and to activate several enzymes, especially those involved in photosynthesis and respiration. It is also involved in protein synthesis and fruit color formation. Although the exact role of chlorophyll production is still unclear, some link between iron and chlorophyll content in plant leaves has been confirmed. Discontinuation of chlorophyll production in iron deficient plants is, of course, the cause of the universal visual symptom, chlorosis. Advantages: • Eliminate iron deficiency; • Improving oxygen uptake; • Increased chlorophyll production; • Increase productivity; Consumption rate kg / ha: foliar feeding -1,5; Root feeding -2.0;
