MICROSEED AIR O2 is a prill (microgranular) fertilizer based on nitrogen, phosphorus and zinc in combination with a Peroxide that releases Oxygen once it comes in contact with soil moisture. MICROSEED AIR O2 creates an AIR BUBBLE around the seed and root system that can reduce the phenomenon of root asphyxia and anoxia, stimulate germination and rooting in adverse situations (e.g., clay soils, soils with waterlogging and compacted soils with tillage soles), and generate an oxidizing side action against soil microorganisms. MICROSEED AIR O2 is characterized by a perfectly spherical, compact and flowable microgranule with a diameter of 1.05 mm ideal for localized fertilization at planting and transplanting. Phosphorus is protected by an organic matrix, which in combination with Zinc results in being fully available for root development. MICROSEED AIR O2 can be distributed by microgranulator or layered with seed, straw cereal seed only, in the hopper (10 kg of MICROSEED AIR O2 for every 100 kg of seed) thus reducing waste, optimizing logistics and maximizing fertilizer efficiency
