What is GAFSA?

GAFSA is the world’s most reactive soft rock phosphate which means it starts releasing plant-available phosphate straight after application as well as providing a sustained release of nutrients for 3-4 years.

Are there other nutrients in GAFSA?

As well as phosphate, GAFSA contains calcium, sulphur and magnesium. It also contains naturally occurring essential micro-nutrients including boron, cobalt, copper, iodine, manganese, selenium, sodium and zinc.

Why use GAFSA?

  • Naturally soluble = no losses due to lock up in the soil or leaching
  • Improves sward palatability = tighter grazing and higher dry matter intakes
  • Encourages clover = fixes ‘free’ nitrogen and improves feed value
  • Rich source of secondary nutrients and trace elements = improves soil fertility and enriches the nutritional value and palatability of grass and forages

Can GAFSA be used if I'm an organic farmer?

Yes. GAFSA 0-29.5-0 powered and GAFSA 0-27-0 are fully approved and unrestricted. GAFSA 0-18-17 and 0-13-26 are Soil Association approved but are restricted and therefore require derogation.
