Calcium is a highly efficient and effective liquid nitrogen organohumic fertilizer with calcium which consists of organic substance of natural origin, humic and fulvic acids and Boron. The form of nitrogen (nitrate) is readily available for plants giving fast and rich growth. The high concentration of Calcium gives the plants and, by extension, the fruits cohesion and resistance to biotic and abiotic factors, while the presence of Boron promises increased fruiting and production. Finally, the presence of Humic & Fulvic acids contributes to chelation and increasing the absorption of nutrients in foliar applications and fertilizing.
