Phosphate Fertiliser
Triple Superphosphate: The 7 Phosphate factors to consider.
- Existing phosphate levels – Is an instant phosphate response required in order to get your farm producing at optimum levels for market conditions or will a prolonged phosphate release be more beneficial?
- Soil pH - Is soil pH in the optimum range for your land class and soil type? Is lime a higher priority? Is a pH neutralizing phosphate source a better option?
- Location and application type – High analysis products will significantly reduce freight and application costs. The higher these costs the larger the saving will be.
- Phosphate retention levels – Do your soils hold onto water soluble forms of phosphate or should a citric soluble phosphate form be considered?
- Rainfall – Are high rainfall events causing phosphate to be lost via runoff. Areas at highest risk are soils with a low phosphate retention in a high rainfall area. Use a steady releasing phosphate source to counter these losses.
- Other nutrients required – Which phosphate source is the most efficient when considering other nutrients required on farm?
- Budget – Are you optimising your fertiliser spending by prioritising the most appropriate nutrients and their specific forms? Does your budget require immediate results, or can it accommodate strategies that provide medium- term benefits?
