TOP K® is a special product for fattening and maturing rapidly absorbed by the plant. Its high concentration of potassium promotes activation of cell respiration processes and activation of sap flow in the phloem, strengthening the plant in the most unfavourable stress and diseases.

TOP K® increases photosynthetic capacity and efficiency, facilitating photoassimilates transport and enzymes formation.

TOP K® improves fruit quality by increasing their colour, weight and ºBrix.
