Pasture Primo

Provides a rich source of calcium and phosphate through a blend of BioAgPhos and lime.
Phosphorus 4.0% | Calcium 37.0%

An immediate and sustained release phosphate fertiliser made from high-grade reactive phosphate rock composted with BioAg’s proprietary phosphate digester. Combined with lime to improve liming effect. Phosphorus, 0% water-soluble, and a minimum of 35% Citric Acid and 65% Formic Acid solubility

Ideal for livestock producers who use contractors to top-dress their pastures or are unable to do their on-farm blending.

  • A natural and sustainable alternative to conventional fertilisers
  • Rejuvenates natural soil fertility and structure by countering soil acidity and providing calcium.
  • Delivers immediate and sustained release of phosphorus
  • Reduces nutrient losses due to common issues such as leaching and lock up
  • Safe for use on all areas, including waterways
  • Small particles enable even distribution; beneficial given P is not mobile in soils
  • Well suited to blending with ameliorants such as lime, gypsum and compost
  • Independent analysis shows that 100% of the phosphorus is bioavailable / plant accessible
  • Can be applied at any time of the year.
  • BioAg Pasture Primo is a certified organic input.

  • Measuring P in soils when using natural phosphate fertilisers

    The Olsen and Colwell soil tests are strongly correlated when using water soluble/chemical fertilisers. However, these tests will likely underestimate plant available phosphorus (P) when fertilising with natural fertilisers such as RPR or BioAgPhos. P is an important el...

  • 'Super' or reactive phosphate rock?

    What is superphoshate? Superphosphate, ‘SSP’ or ‘super’ is a fertiliser processed using sulphuric acid to boost the water solubility of phosphorus. Various strengths of P plus additions of nitrogen make up a range of products that feature a high proportion of nutrients ...
