Detailed description of production method 

Flash carbonization was performed in a vessel pressurized to 0.8 - 3.4 MPa with air. Electric heating coils at the bottom of the pressure vessel ignited the lower portion of the biomass. After 360s, compressed air was delivered to the top of the pressure vessel and flowed through the packed bed of feedstock to sustain the carbonization process. Pressure within the ractor was maintained at the specified range. After sufficient air was delivered to carbonize the corncob, air flow was halted and the reactor cooled overnight. The charcoal was removed from the reactora nd allowed to equilibrate under a fume hood for 2 days.

Assurance provided for that the feedstock does not contain inorganic wastes (plastic, rubber,PCB, etc.), paints or solvents?

Potential utilisation in soil
Would it be suitable for soil reclamation in general? 
No information
Would it supply nitrogen, phosphorous and/or potassium to the soil? 
No information
Would it supply mesoelements (Ca, Cl, Fe, Mg, Na, S, Si) to the soil? 
No information
Would it supply microelements (B, Co, Cu, Mn, Mo, Zn, V) to the soil? 
No information
Would it provide sufficient amounts of special nutrients to the soil? 
No information
Would it increase the humus/organic matter content of the soil? 
Yes
Justification, references 

The carbon content of the soil would be increased over the long term with biochar addition to soil (Budai et al. 2015, in prep)

Would it suffice as a main component of growing media? 
No information
Would it suffice as an additive to growing media? 
No information
Would it improve the structure of compacted soil and/or contribute to soil crumb formation of poorly structured soils? 
No information
Would it be suitable for physical stabilisation and/or texture improvement of loose, quagmire soils? 
No information
Would it be suitable for amending sandy soils? 
No information
Would it be suitable for erosion prevention? 
No information
Would it be suitable for amending acidic soils? 
Yes
Justification, references 

Preliminary laboratory results show a buffering of acidic soils using this biochar at more than 5 m% amendment rates

Would it be suitable for amending saline and sodic soils? 
No information
Would it reduce the mobility and availability of the contaminants? 
No information
Would it intensify the mobility, availability of the contaminants? 
No information
Would it intensify physical, chemical, and/or biological degradation and decomposition of contaminants? 
No information
