Following best practice recommendations for storing fertilisers is essential to maintaining the quality and integrity of the granules.
Fertiliser will break down due to exposure to the environment, so it’s imperative to keep it dry and protected from all weather conditions until it’s time to apply it to paddocks.
We recommend the following best practice guidelines for storage:
- Keep fertiliser protected from the weather and sunlight in an enclosed shed.
- Ensure the storage environment is clean and free of dust and dirt.
- Maintain storage temperature between 5 and 30˚C (some fertilisers are sensitive to extreme temperatures).
- Protect fertiliser from exposure to moisture, which can create lumps and dust compromising the consistency and accuracy of application.
- Maintain good stock rotation management, working on a first in, first out basis.
- Store incompatible fertilisers in separate areas, such as urea and ammonium phosphate fertilisers.
- Consider storage conditions and your fertiliser’s sensitivity to moisture. For example, fertilisers containing nitrogen (N) or potassium (K), including in blends, are more likely to absorb moisture in humid conditions. Whereas straight P fertilisers are less affected by humid conditions.
- Be aware that degraded fertiliser granules and those products containing a high level of fines, will absorb moisture faster than fresh, good quality compounded fertiliser. Fertiliser that absorbs moisture has a greater chance of further degradation that could cause issues with modern seeding equipment. In general terms, phosphorus based fertilisers will store better than MOP based NPK's (blended or compounded) &/or phosphates blended with urea.
