MACRO-SORB foliar is a biofertilizer based on amino acids, produced by enzymatic hydrolysis, and essential micronutrients. It allows for greater absorption and transport of nutrients through the leaves into the plant. The action of L- amino acids and substances with phytohormonal effect in MACRO-SORB foliar helps to regulate the opening of the stomata, increase water potential, regulate osmotic pressure, slow down photorespiration, and increase net photosynthesis.Rate: 1/2 oz. - 2 oz. per 1000 sq. ft. every 7-15 days. In applications with composites of copper, sulfur or oil its recommended not to exceed dosages of 1/4 oz. per 1000 sq. ft.
