Green algae extract is a calcium rich extract of calcareous green seaweed. The good concentration of bio-available form of calcium has many secondary benefits in plant growth. It support plant with a strong vascular system to takes up water and nutrients more effi- ciently, increasing the Brix or sugar content of the plant. It also helps in maintaining plants physiology by boosting the self defense mechanism of plant. Calcium supplement increases leafs thickness by improving plant cell wall structure and produces thicker leaf and fruit structure which make them physiologically stronger helping in self defense and this also leads to better quality and grade of produce. It also has rich content of other macro and micro- nutrients along with active metabolites and plant hormones. It improves the overall vigor of plant and helps in in- creasing yield.
