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.

Need More Technical Information?

GAFSA brings rich source of secondary nutrients and trace elements. These improve soil fertility and enrich the nutritional value and palatability of grass and forages.

Calcium (Ca)	Sulphur (S)	Magnesium (Mg)
Buffers surface acidity and sweetens pastures	Increases N uptake and efficiency	Improves mineral balance within the sward
Improves soil structure and fertility	Optimises photosynthesis for maximum growth	Reduces risk of grass tetany (staggers)
Strengthens cell walls which increases resistance to stress and damage	Increases protein levels in grass and forage for higher feed value	Stimulates appetite leading to increased DM intake and utilisation
Essential for muscle, bone and teeth development	Increases DM production for better utilisation	Improves palatability and aids tighter grazing
GAFSA contains naturally occurring essential micro nutrients, including: Boron, Cobalt, Copper, Iodine, Manganese, Selenium, Sodium and Zinc

Need a Carbon Footprint?

Our aim is to provide specific carbon footprints for our products, improving accuracy for recording and reporting. NUTRI-CO2OL, our independently ADAS verified carbon footprint model, was developed to account for changes in raw material sourcing, production and blending sites.
