Fertilizer is an investment sitting in a bag. Moisture, heat and poor stacking can ruin it.
Why fertilizer cakes
Urea, DAP and many NPK grades attract water from humid air. Once granules bond together, they become hard blocks that spread unevenly and lose value.
Good storage habits
- Store in a dry, shaded, ventilated building with a sound roof.
- Stack bags on pallets or boards, never directly on the floor.
- Keep stacks away from walls and do not pile them too high.
- Reseal opened bags and use them first.
- Keep fertilizer away from seed, feed, food and fuel.
Keep products separate
Store urea and nitrate-based fertilizers apart from elemental sulphur and organic materials, and keep them away from flames and heat.
Inspect
Check stock regularly. Lumps can be broken before use, but badly caked product should be used on a trial area first.
We can advise on storing and delivering fertilizer so it arrives in good condition.
