Research Project: Weathering of Sewage Sludge Biochar in Soil

Location: Soil and Water Management Research

Project Number: 5062-12130-008-048-N
Project Type: Non-Funded Cooperative Agreement

Start Date: Aug 1, 2024
End Date: Aug 1, 2026

Objective:
Assess the chemical and physical changes in biochar (cashew trimmings and sewage sludge) after being applied to soil.

Approach:
The cooperator will conduct a sequence of greenhouse based experiments to assess the aging of sewage sludge biochar in two contrasting Brazilian soils. Sub-samples will be sent to the USDA-ARS laboratory for analysis. In addition, extractions will be performed on the soil samples to determine the impact on heavy metals during the greenhouse incubations.
