Journal ArticleDOI
Near-Infrared Reflectance Spectroscopy–Principal Components Regression Analyses of Soil Properties
TL;DR: In this article, the authors evaluated the ability of NIRS to predict diverse soil properties, including total C, total N, moisture, cation-exchange capacity (CEC), 1.5 MPa water, basal respiration rate, sand, silt, and Mehlich III extractable Ca.
Journal ArticleDOI
Impact of biochar amendments on the quality of a typical Midwestern agricultural soil
TL;DR: In this paper, the authors investigated the impact of biochar amendments (0, 5, 10, and 20 g-biochar kg−1 soil) on the quality of a Clarion soil (Mesic Typic Hapludolls), collected (0-15 cm) in Boone County, Iowa.
Journal ArticleDOI
Biochar impact on nutrient leaching from a Midwestern agricultural soil.
TL;DR: In this article, the authors quantify the impact of biochar on leaching of plant nutrients following application of swine manure to a typical Midwestern agricultural soil, and suggest that soil-biochar additions could be an effective management option for reducing nutrient leaching in production agriculture.
Journal ArticleDOI
The Charcoal Vision: A Win–Win–Win Scenario for Simultaneously Producing Bioenergy, Permanently Sequestering Carbon, while Improving Soil and Water Quality
TL;DR: In this article, a distributed network of fast pyrolyzers may be a sustainable platform for producing energy from biomass, and application of the charcoal co-product to soils may be key to sustainability.
Journal ArticleDOI
Review of the pyrolysis platform for coproducing bio-oil and biochar
TL;DR: The pyrolysis platform for producing bio-oil and biochar from biomass appears to be a practical, effective, and en- vironmentally sustainable means of producing large quantities of renewable bioenergy while simultaneously reducing emissions of greenhouse gases as mentioned in this paper.
