Abstract
A method is provided for applying porous carbonaceous particles to soil for purpose of cultivating plants having roots, where at least 95% of the porous carbonaceous particles have a particle size less than or equal to 10 mm. The method incorporates the porous carbonaceous particles into the soil surrounding the plant roots at a depth of between 0-24 inches from the soil surface, where the porous carbonaceous particles are positioned in the area surrounding the roots of the plants at a ratio of between 1:999 to 1:1 porous carbonaceous particles to soil.
