Range and method of use

CARBONBOR® Si is a foliar fertilizer with a treatment effect and the possibility of removing latent and apparent deficits of boron and which concurrently supplies silicon and carbon. Boron is significant for the material and energy metabolism of the plant. It raises the quality of its pollen and its resistance to frost. Silicon has a positive influence on the health of the plant and on increasing resistance to wind damage (strengthening cell walls). Carbon has a positive effect on the dynamics of photosynthesis, the production of sugars and amino acids. CARBONBOR® Si can be used with all types of cultivated annual and perennial crop plants.
