Macro and micro nutrient characteristics of four biochar-amended soils from Oregon, 2018

Research has suggested that biochar soil amendments have the ability to improve soil water retention, but results have not been consistent or predictable across soil types. The objective of this project was to evaluate the potential for biochar soil amendments to mitigate agricultural drought by characterizing their impacts on soil hydraulics and plant growth across a range of agricultural soil conditions. This data set contains soil moisture retention curves and unsaturated hydraulic conductivities for four Oregon agricultural soils amended with biochar. Gasified biochars made from wheat straw (AgEnergy, Spokane, WA) and conifer wood (BioLogical, Philomath, OR) were tilled into soils at experimental stations in Madras (loam), Pendleton [...]
