Granulation means improved spreadability, as well as ensuring that the fertiliser behaves exactly as dicalcic phosphate should.

Nitrogen fixation is the key to achieving optimal pasture growth (or ‘vigorous clover growth’).

Most New Zealand swards consist of clover and rye/fescue grass. Clovers originate from the Mediterranean, where there are warm summers, high pH soils and high levels of natural soil phosphorus (P). As well as being an efficient form of slow-release nitrogen (N), clovers remove trace elements from the soil and make high-quality animal feedstuff.

New Zealand soils have naturally low P levels and are generally acidic, with a lower pH. For clover to thrive, the soil phosphor levels sometimes need to be raised and the soil acidity controlled using lime or fertilisers high in calcium.

On new pastures, clovers can fix the equivalent of 400kg N/hectare/year. On established pastures it can fix about 100-150kg N/hectare/year – enough to replace the production losses of pastures growing 13 to 15 tonnes of DM/hectare/year.

With nitrogen costing around $1.50/kg N applied, this can save you $150 to $220/hectare/year, every year.

Slower and more efficient nitrogen release means:

  • Fewer applications are needed, reducing field movement and preserving the soil structure and microorganisms
  • Reduced costs on labour and spreading
  • Lower urea application leads to less chance of damage from crop leaf burning
  • The pasture grasses and clover composition remain as they were
    before application
  • Less damage to clover nitrogen fixation in pastures
