Ammonium Poly Phosphate APP
BENEFITS OF APP • Unique polymer characteristics ensure, controlled deliver of phosphate across a wide range of soil types. • Ideal starter fertilizer made from the highest-grade materials, yielding a clear colorless solution. • Able to sequester & free insoluble micro elements bound in soils, making them plant available. • APP has the ability to free insoluble microelements such as zinc and copper bound in the soil. It sequesters them making them available to the plant. • It reduces interference of soil calcium for an enhanced phosphate uptake.
WHAT ARE POLYPHOSPHATES? Well-known phosphorus sources such as MAP and DAP contain phosphorus which is in the ‘orthophosphate’ form i.e. these are single phosphate molecules which easily become locked and unavailable to plants when applied to high pH, calcareous and acidic soils fixing phosphorus. The phosphorus in ammonium polyphosphate (APP) is not subject to this lock up. The reason for this is its long chain structure. During production of ammonium polyphosphate the extreme temperature of the reaction forces water out of the structure, thus forming polymer chains between the phosphate molecules. These polymer chains vary in size, giving the effect of a slow release phosphorus source.
APP CHARACTERISTICS:
pH: 6.0 – 7.0;
Specific Gravity: 1.40 – 1.41
International Analysis W/W%: 11.0% N, 37% P2 O5 .
