- Ammo-Phos MAP
Ammo-Phos MAP is a high analysis, free-flowing soluble ammonium and phosphate fertiliser with a nitrogen to phosphate ratio of 1:2 (DAP is 1.8:2). It is generally light to dark brown.
-
Why Use
- For drilling or banding close to the seed, where a high phosphate supply is required
- Less risk of seed burning compared to DAP due to virtually no free ammonia being released
- MAP-based products are superior on alkaline soils compared to DAP
-
Safety Information
Ammo-Phos MAP Safety Data Sheet
Caution when mixing
Although Ammo-Phos MAP generally mixes well with other products, it is not compatible with the following:
Superphosphate and Magnesium OxideAmmo-Phos MAP can be compatible with the following under certain circumstances:
Dry Lime and Sulphur Super 30Segregation may occur when mixed with a product with differences in particle size.
Flexi-N (magnesium-coated Urea) can be used as a substitute when mixing with Superphosphate-based products

Benefits
For drilling or banding close to seed, where a high phosphate supply is required
Less risk of seed burning compared to DAP due to virtually no free ammonia being released
MAP based products are superior on alkaline soils compared to DAP
Ammo-Phos MAP is suitable for drilling or banding close to seed as there is less risk of seed burning compared to DAP due to virtually no free ammonia being released, which is toxic to seedlings.
Ammo-Phos MAP is used for pea fertiliser mixes, potatoes and in some regions forage brassica crops. It is suitable where a high phosphate supply is required and soil potassium levels are good. It can also be used in base fertiliser mixes formulated for crops such as cereals and maize. -
Application and storage
Application rates and advice will vary, according to base soil fertility. For forage brassica crops, rates range around 150-250kg/ha.
Application rates and advice are typically 400kg/ha in Mid October. Actual spreading rates will vary according to farm type, climate, productivity, soil type and crop type. Soil testing and fertiliser plans are available to ensure you use the right product at the correct rate. Call our Customer Centre for information.
As with most solid fertilisers, Ammo-Phos MAP can be stored over a season as long as it is kept in a cool, dry, well ventilated area.
Ammo-Phos fertilisers contain monoammonium phosphate (MAP), which is manufactured by chemically reacting one molecule of ammonia with one molecule of phosphoric acid. Diammonium phosphate (DAP) is made the same way, except that two molecules of ammonia are reacted with each molecule of phosphoric acid. As MAP has only half as much ammonia in proportion to the phosphate, there is virtually no release of free ammonia, and therefore can be sown closer to seed compared to DAP.
MAP has been found to be superior on alkaline soils, due to (i) its acid nature (compared to DAP, which has a slight alkaline effect) and (ii) the greater volume of soil enriched with phosphorus.
