KELFER is particularly suitable for preventing and treating physiopathies due to iron deficiency. These are rapidly soluble microgranules for radical use. It allows a rapid vegetative recovery of plants in a strong state of deficiency. It can also be used in the prevention of any iron physiopathies when the first symptoms appear. The plants treated with KELFER are in an excellent vegetative-productive state, they take on a bright green color thanks to the optimal photosynthetic activity guaranteed by the application of the product.
