The invention provides for methods, devices, and systems for pyrolyzing biomass. A pyrolysis unit can be used for the pyrolysis of biomass to form gas, liquid, and solid products. The biomass materials can be selected such that an enhanced biochar is formed after pyrolysis. The biomass can be pyrolyzed under specified conditions such that a selected biochar core is formed. The pyrolysis process can form a stable biochar core that is inert and/or resistant to degradation. The biochar or biochar core can be functionalized to form a functionalized biochar or functionalized biochar core. Functionalization can include post-pyrolysis treatments such as supplementation with microbes or physical transformations including annealing and/or activation.

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.

The present invention provides a method for improving tobacco-planting soil by using biochar, and belongs to the technical field of soil improvement. The method includes the following steps: (1) carbonizing agricultural and forestry waste to obtain biochar; (2) pulverizing the biochar to obtain a biochar particle; and (3) mixing the biochar particle with a plow layer of the tobacco-planting soil to obtain biochar-improved soil. Compared with tobacco-planting soil that is not added with the biochar (control), the method provided by the present invention greatly increases carbon and nitrogen contents of the tobacco-planting soil, and significantly increases moisture and available potassium contents of the tobacco-planting soil, which is beneficial to ensure the sorption of soil moisture and nutrients by the tobacco plant. The biochar prepared by the present invention has strong stability and can interact with the soil for a long time, and also has good effects on ameliorating soil compaction and improving the aeration performance or the like, thus helping to eliminate or reduce an environmental factor that is not conducive to the growth of tobacco caused by an obstacle of continuous cropping and significantly increase the biomass of the tobacco plant.
