Raw Biochar for your own experiments
Like our other formulas this raw biochar is made from the best woody charcoal material we can source. Washed and dried, high-surface-area condominiums for your own special brand of enrichmen. Nothing else is added, so go to town with your own recipe, put it in your chook pen, worm farm or on your compost heap. We strongly recommend charging it up and not using it in a totally raw state but if you are buying this you already know that!
Our raw biochar still permanently sequesters carbon and transforms your soils.
Our biochar is the least amount of effort you can expend to permanently transform your soil. More permanent soil carbon than compost, less bulk and weight and perfectly convenient. Just sprinkle on, rake lightly and stand back. The benefits of it will just compound in years to come.
How to prepare it
The following are just a grab-bag of suggestions:
- Mix with a slurry made from worm castings and age in a warm place for at least a week.
- Mix with a small amount of the soil you will be adding to inoculate it with the prevalent bacteria
- Add to the floor of your chicken coop. It will absorb odours and be inoculated with nitrate and phosphate-rich chicken manure. Add these to your garden in the usual way.
How to apply
There are several ways to apply. Either sprinkle lightly at a rate of one handful per square metre, then add mulch or bark litter. If you are able to convert the entire growing layer, then apply at a rate of 4 litres per square metre to the top 5 to 10 cm of soil. When preparing new gardens or lawns, add to the bulk loam at a rate of 10% by volume.
When planting new trees in clay soil, put a 2 litre tub of clay soil formulation biochar into the planting hole of your new tree. Then add a 3 cm layer of loam before placing the root ball on top.
Use a 5cm layer at 20% concentration on all exposed areas of drab clay soil in your garden to spruce up the visual appearance of your garden. It will permanently transform it to give it a strong, dark, rich look. This provides a better contrast for the other colours in your garden especially lush greens and whites.
