2013 Annual Report

1a. Objectives (from AD-416):
To design biochar as a soil amendment to improve the physico-chemical characteristics of Coastal Plain soils.

1b. Approach (from AD-416):
Biochar will be made from different feedstock material along with different thermal and chemical activation conditions to produce specific chemical/physical biochar characteristics. The biochars will be designed to allow its eluviation from the surface horizon into subsurface hard layers. Each designed biochar's sorption and leaching characteristics in sandy soil will be evaluated using standard isotherms and laboratory incubation techniques.

3. Progress Report:
This research is directly related to inhouse objective 1. Designer biochars and blends with other feedstocks were successful at improving targeted soil limitations. Guidelines for designer biochar tailored to improve specific soil properties: Designer biochars were produced and their impact determined on improving carbon sequestration, fertility, and water holding capacity of sandy soils. From these results, guidelines for their creation and specific uses were developed.
