How do you use biochar?
Herein, how do people use biochar?
The many uses of biochar In the modern world, the uses multiply: adsorber in functional clothing, insulation in the building industry, as carbon electrodes in super-capacitors for energy storage, food packaging, waste water treatment, air cleaning, silage agent or feed supplement.
Likewise, is there a difference between charcoal and biochar? The easy answer to this question- what is the difference between biochar and charcoal - is -biochar is used as a soil amendment, and charcoal is used as a fuel. Well made biochar will be lighter in weight, and contain less BTUs per volume than charcoal.
Consequently, how much biochar do I add to soil?
From everything we have seen in our own use and through the biochar research of others a good “rule of thumb” is 10% of the planting area should be biochar. If your soil is absolutely horrible you should probably start with a 50/50 mix of biochar and compost and apply about 1/4 lb per square foot.
How does biochar work in soil?
With its pores and its electrical charges, biochar is capable of both absorption and adsorption. Absorption (AB-sorption) is a function of pore volume. The larger pores absorb water, air and soluble nutrients like a normal sponge. Adsorption (AD-sorption) depends on surface area and charge.
