Maxi MAP is a granular monoammonium phosphate fertilizer sold in 25kg bags. MAP has the highest phosphorus content of the common solid fertilizers, plus ammonium nitrogen that helps the plant take up the phosphorus. It promotes fast germination, a strong root system and vigorous early growth. It is slightly acidic, so it works especially well on alkaline soils, and it is safe to place near germinating seed. Use it on maize, wheat, soybean, potato, sunflower, vegetables and pasture.
