Common Questions
How do I read the N:P:K ratio on this blended fertiliser?
The N:P:K ratio shows the percentage by weight of Nitrogen (N), Phosphorus (P) and Potassium (K) in the blend. For example, a 10:8:6 blend contains 10% nitrogen, 8% phosphorus and 6% potassium. This allows you to compare nutrient content between different blended products and calculate the amount needed based on your soil test recommendations.
Why is a soil test essential before using this blend in SE Queensland?
Soil P and K deficiencies vary significantly across SE Queensland depending on soil type — coastal sandy soils, basalt downs and red clay country all have different nutrient profiles. A soil test identifies your specific deficiencies and yield targets, ensuring you apply the right blend at the right rate rather than over or under-applying nutrients.
What application rate should I use for tropical and subtropical pastures in SE Queensland?
Application rates depend entirely on your soil test results and desired pasture yield target. Your soil test report will recommend specific rates based on current soil nutrient levels and your production goals. Contact TGRM rural supplies with your soil test results for personalised rate recommendations for your property.
How should I store this blended fertiliser to prevent caking?
Store HALF BULK BAG FINE GYPSUM JNJ 1223366 in a dry location away from moisture and humidity. Keep the bag sealed or covered to prevent water absorption, which causes the granules to stick together and cake. Proper storage maintains product flowability and ensures even application when you're ready to spread.
Is a blended fertiliser more cost-effective than buying straight fertilisers separately?
Blended fertilisers often provide better value when you need all three nutrients (N, P and K) because they reduce labour costs — you apply once instead of making multiple passes with different products. However, cost comparison depends on your specific nutrient requirements from a soil test. TGRM rural supplies can help you compare options based on your property's needs and budget.
