How To Use Biochar

How To Garden with Biochar

Proper dispersion is a key component for all biochar applications. A piece of biochar, the size of a sugar cube, has the surface area equivalent to that of a basketball court. When biochar is applied in chunks it has less available surface area then that of finer High Porosity (HP) biochar.

Surface area is crucial for storing nutrients, microbes and water. Biochar made from wood pellets or chips, does not have the ability to be easily broken down. Waiting for wood pellets or chunky biochar to increase the available surface area, will take an undesirable amount of time. It’s like comparing a sponge and a rock of the same size (volume), the rock weighs more (greater density) than the sponge, but the sponge has a much greater ability to absorb. HP Biochar has deep and complex pores which help to store nutrients, microbes and water.

Think of Sunriver High Porosity Biochar as an organic sponge for your garden. For best results, get the biochar to the root zone as quickly as possible. For potted plants or raised beds, add 5 – 10% by weight (approx. 1 oz biochar/ lb of soil) & mix thoroughly with your soil. 1 cu ft (7 Gal) covers approx. 50 sq ft of open ground whether lawn, garden or flower beds. Yearly additions, ideally as a fall top dressing, will continue to improve soil quality. Adding Sunriver High Porosity Biochar to your actively aerated compost tea can help kickstart the mycorrhizal fungi for root development.
