ORANGFOL 20 – 20 – 20 + 2% AA is a soluble NPK fertilizer enriched with amino acids and microelements applied in fertigation, in the form of soluble crystals. Its balance makes it special for moments of greater biological activity. Its contribution of organic matter makes its effect to prolong for several weeks. It is used as a complement to the fertilization of crops and bottom, especially in times of greater activity of the crop, that is to say, in active growth, fructification and fattening of fruits. The nitrogen combined with carbohydrates is the lignin of the cell walls that is part of the energy system of the plant and participates in the synthesis of vitamins and auxins. Phosphorus carries out the energy transfer of the whole plant, is essential in the formation of the seed, stimulates the growth of the root, improves the firmness of the soil and accentuates the organoleptic characteristics of the fruit. Potassium increases the photosynthetic activity and intervenes in the water regulation mechanisms of the plant. It is a necessary nutrient in the formation of proteins and in the synthesis of carbohydrates. It acts as an activator in cellular respiration processes and enables the active conformation of numerous enzymes.
