BLACK GRIT TRIAL
Two identical garden beds
With Black Grit
No Black Grit
I am so impressed with your black grit and other grow products and the photos clearly disclose how good they are. The comparison of the 2 garden beds convinces me to be an ongoing user of them to ensure outstanding vegetable and plant growth. I am also encouraging my family and friends to use it too. Thanks again for your great advice that really works and also for your Sat and Sun sessions on 3AW radio.

Soil Health, Fertility and Sustainability
Black Grit is a fused calcium magnesium silicate phosphate soil amendment/fertilizer 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 macroelements 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.
Black Grit can be used as a starter in a crop or broadcast over pasture at any time of the year.
It has taken decades in some cases for soils to deteriorate, change also takes some time, but the sooner Black Grit is applied the sooner it can get to work in the soil. Typically, within 24 hours of application with some moisture Black Grit will start to digest soil acid and provide macronutrients to the plant.
Simply sprinkle 40g p/m2 around the garden and water in.
1kg of Black Grit will treat up to 20m2 garden.
Apply Black Grit every 3-6 months
