Product Type
Nitrogen and Phosphorus Fertilizer
N-PHOSPHATE
Liquid monoammonium phosphate fertilizer with high phosphorus concentration for early growth, rooting and phosphorus supply.
N-PHOSPHATE is a liquid monoammonium phosphate fertilizer formulated for the initial growth phase of crops, including periods immediately before and after seeding, planting or transplanting.
It contains 12% total ammoniacal nitrogen and 61% phosphorus pentoxide, is free of chloride and sodium, and is described as especially suitable during the first half of the crop cycle and in situations where phosphorus availability is limited.

Key benefits and agronomic effects
- Supports the growth of high-quality roots and shoots.
- Provides a highly concentrated source of phosphorus and nitrogen.
- Promotes rapid phosphorus uptake through phosphate (H2PO4).
- Provides an acidifying effect on the soil solution.
- Helps improve nutrient use where phosphorus availability is restricted.
How it works / Technical advantages
N-PHOSPHATE is described as a stable, high-purity liquid solution that is freely soluble and quickly dissolving. The datasheet highlights its use during the first half of the crop cycle and its acidifying effect on the soil solution, which favours the solubility of phosphorus and micronutrients, particularly in calcareous soils.
Application rates and timing
Application Guidance: Foliar recommendations vary by crop. Repeat phosphorus-correction applications at 10-14 day intervals where the datasheet indicates this is necessary.
Foliar application
| Crops | Timing | Dose | Notes |
|---|---|---|---|
| Cereals | Spring | 5-6 L/ha | Apply when deficiency is suspected, root uptake is limited by soil/weather conditions, or SAP analysis shows low nutrient status. Repeat at 10-14 day intervals as necessary. |
| Maize | 4-8 leaves | 5-6 L/ha | Apply when deficiency is suspected, root uptake is limited by soil/weather conditions, or SAP analysis shows low nutrient status. Repeat at 10-14 day intervals as necessary. |
| Potatoes | 7-10 days after tuber initiation | 15 L/ha | The datasheet notes that crops are usually meeting along the rows at this stage. |
| Other crops | As required | 5-6 L/ha | Apply when deficiency is suspected; repeat after 10-14 days if required. |
Additional technical information
Target problem / deficiency symptoms
The datasheet positions N-PHOSPHATE for situations where phosphate uptake through the roots is inadequate, including adverse soil or weather conditions and low phosphorus status. It also highlights use in calcareous soils where phosphorus availability can be limited.
Mixing & compatibility
Do not apply in a pesticide tank mix when the crop is showing deficiency symptoms, is under stress, or is experiencing adverse weather conditions.
Frequently asked questions
What is N-PHOSPHATE?
It is a liquid monoammonium phosphate fertilizer containing 12% nitrogen and 61% P2O5.
When is N-PHOSPHATE most suitable?
The datasheet highlights the initial growth phase, immediately before and after seeding or planting, and the first half of the crop cycle.
What is the foliar dose for cereals and maize?
The datasheet recommends 5-6 L/ha for cereals in spring and for maize at the 4-8 leaf stage.
Can N-PHOSPHATE be used where phosphorus uptake is limited?
Yes. Its datasheet specifically addresses situations where soil or weather conditions limit root phosphate uptake and where phosphorus status is low.
Are there tank-mix precautions?
Yes. The datasheet advises against pesticide tank mixes when crops show deficiency symptoms, are under stress or face adverse weather conditions.
