Carbon Cycling

APPLICATIONS FOR CARBON SEQUESTRATION

TOPICS:Biochar application research | Biochar land application study


BIOCHAR APPLICATION RESEARCH 2008

1. CO-COMPOSTING CHICKEN LITTER WITH BIOCHAR

This project evaluates the influence of biochar additions on chicken litter composting and the influence of composting on charcoal properties (biological treatment). Chicken litter is produced in huge amounts in Georgia and represents a considerable challenge as well as opportunities for alternative uses.

Objectives

  • Reducing the loss of nitrogen (NH3 volatization)
  • Preparation of a better more recalcitrant compost
  • Increasing surface charges of biochar

2. COMPARISON OF CARBONIZED CROP RESIDUES (ZEA MAYS) WITH UN-CARBONIZED CROP RESIDUES ON CROP PERFORMANCE

This project assesses the effect of carbon remaining/applied in the field either carbonized or not. The influence on fertilization, water and nutrient use efficiency will be assessed.

Objective

  • Developing and study a new land use system with biochar carbon sequestration and nutrient cycling

3. RESEARCHING BIOCHAR AS AN AMENDMENT IN COMMERCIAL POTTING SOILS

Many potting soils do contain biochar, but its effectiveness will be assessed in this study. We compare three different potting soils and 4 different commercial soil amendments. Potting Soil Poster: View PDF>>
