### What is it – why is it so good?


	CharBoost BioChar is a high quality horticultural charcoal/biochar. As a permanent source of carbon, CharBoost acts as a sponge to hold onto water and nutrients, making it an ideal home for millions of beneficial soil microbes.


	[Charboost](/charboost-biochar/) is an Australian product made in Queensland from Spotted Gum (Corymbia Maculata).



	It is a powerful soil substrate that improves soil fertility, it is often blended in garden beds or potting mixtures to:


	

- Enhance Soil Vitality	

- Stimulate Plant Growth	

- Increase Nutrient Holding Capacity	

- Increase soil microbial Activity	

- Builds Carbon Reserves for Future Crops 
	BioChar works to improve moisture retention in sandy soils, but also reduced tensile strength in hard-setting soils (like clay), some studies have even shown biochar to suppress soil borne diseases. Why not do a trial in your own home garden and let the results speak for themself!
