Potential Drawbacks of Using 12-24-12 Fertiliser

Risk of Over-Fertilisation

One of the significant risks of using 12-24-12 fertiliser is the possibility of over-fertilisation. Since this fertiliser contains a high level of phosphorus (24%), excessive application can lead to nutrient imbalances, causing stunted growth, leaf burn, or even root damage in some plants. Over-fertilisation can also result in nutrient runoff, which not only wastes fertiliser but can also harm the environment.

Agricultural expert Dr. William Clark advises, “Applying too much fertiliser can do more harm than good. Always start with smaller quantities and adjust based on plant response.”

High Phosphorus Concerns

High phosphorus levels can be an issue, especially in areas where the soil already has adequate phosphorus content. The excessive build-up of phosphorus can hinder the plant’s ability to absorb other essential nutrients, such as iron and zinc. Moreover, phosphorus runoff can enter nearby water bodies, leading to environmental problems like algal blooms and reduced water quality.

Ways to Avoid Common Mistakes

  • Conduct Soil Testing: Regular soil testing helps determine if your garden truly needs additional phosphorus before applying 12-24-12 fertiliser.
  • Follow Application Guidelines: Always adhere to the recommended application rates on the fertiliser packaging to avoid over-fertilisation.
  • Monitor Plant Responses: Watch for signs of nutrient excess, such as yellowing leaves or stunted growth, and adjust fertilisation practices accordingly.

By taking these precautions, you can minimise the risks associated with using 12-24-12 fertiliser and protect both your plants and the environment.
