An NPK fertilizer carries nitrogen (N), phosphorus (P) and potassium (K) in fixed proportions printed on the bag, such as 15-15-15. Every granule has the same mix, so spreading is simple and even.
Choosing the grade is the real skill: leafy crops want more nitrogen, root and fruit crops more potassium, young crops more phosphorus. We help you match the grade to the crop and the soil test. Ask us which grades we can supply.

How to use
- Use a balanced grade early in the crop's life and a nitrogen-rich or potassium-rich grade later, following the crop stage.
- Apply beside the plants or as a band, then irrigate.
- Top up nitrogen with urea if the crop needs more than the grade provides.
- Check the soil test: if phosphorus is already high, choose a grade with less of it.
Storage and care
- Keep bags sealed and dry.
- Stack on pallets away from walls.
- Do not leave opened bags in the sun.

Frequently asked questions
How do I choose between grades?
Match the grade to the crop group and soil test. Tell us the crop and stage, and we will recommend one.
Is NPK better than single fertilizers?
It is more convenient and even, but single fertilizers allow exact tuning. Many farms use both.
Can NPK replace organic matter?
No. It feeds the crop but does not build soil; combine it with compost or manure.
