ACTION BIOSTIMULATING
Permitted in Organic Farming
Grena Superferro +S is recommended for basal fertilization of crops that require action at various levels: ferric chlorosis and excessive limestone. Grena Superferro +S develops an corrective action balancing soil pH, helping to the assimilation of the ferric compound.
The outstanding biostimulant action of Grena Star is due to the high content of amino acids for greater radical proliferation and a chelating action on the elements already present in the soil with a long-lasting effect over time.
The polyamines present have important roles:
• anti-stress effect after transplantation, hydro, adverse environmental conditions (frost and hail), stages of root asphyxia, weeding;
• increase of the Brix Degree (°Bx), being recognized modulators of various “channel” receptors, as the one for potassium;
• attract the pollinating insects (bees, butterflies, moths, beetles) responsible for entomophilous pollination.
