Soil Health, Fertility and Sustainability.

Black Grit 0-8-0 is a blend of Rock Phosphate and Limestone that has been used successfully around the world for the last century in low fertility acid soils where it increases pH and CEC (Cation Exchange Capacity) and provides and helps unlock P in the soil.

Black Grit provides soil amendment and fertilizer together in ONE application to acid soils. It assists in increasing pH to a sustainable level whilst providing useful amounts of macro elements Ca, Mg, Si and P as well as a range of micronutrients. It is not water-soluble therefore does not leach or wash away.

Black Grit is made from naturally occurring minerals not chemically treated. It works with the natural soil chemistry to digest soil acid as well as providing minerals in a plant-available form. It is high in plant-available calcium (24%), magnesium (10%) silicon (11%) and phosphorus (8%) and also acts as an alternative to lime.

Simply sprinkle 20g p/m2 around the garden and water in. 1kg of Black Grit will treat up 50m2 garden.
