Feeding the Roots: Phosphorus for Profitable Crops

In this episode, we discuss phosphorus as a key nutrient across a range of crops, from cereals and potatoes to vegetables, and review recent research and its impact on financial margins. We’ll also cover how farmers and growers can get involved and learn more. Joining us are Agrii’s Tom Land, Fertiliser Technical Manager, and Don Pendergrast, Technical Manager for Specialty Crops. 

Episode overview:

• Phosphorus is vital for crop establishment and root development: It supports energy transfer, growth, and fertility in cereals, potatoes, and vegetables. Declining phosphorus levels in grain analysis suggest a need to reassess application strategies.
• Precision application is key for specialty crops like potatoes: Targeting phosphorus placement near the root zone improves uptake and tuber development. Technologies like microgranules, liquid formulations, and coated fertilizers are being trialled.
• New R&D focuses on improving phosphorus efficiency: Agrii is testing products like Release in both field and glasshouse trials to enhance root mass and nutrient uptake, especially in soils with challenging pH levels.
• Return on investment matters more than maximum yield: Trials show that medium-input strategies often outperform high-input ones in profitability. Early investment in nutrition - especially at seedbed stage - is crucial for root crops.
• Farmers can stay informed via grain testing and Agrii events: Grain tests (approx. £45) offer valuable feedback on nutrient uptake. Agrii’s website, social media, and events like the Potato Partnership provide ongoing insights and trial results.
