The Soil Science Laboratory aims to develop and extend best management practices for maximizing agricultural productivity while minimizing adverse environmental impacts through scientific research and training endeavors.

Focal areas of the laboratory are:

  1. Soil conservation and fertility improvement
  2. Value-added reuse of agricultural byproducts
  3. Fate and transport of nutrients and contaminants in agricultural ecosystems
  4. Bioretention for stormwater treatment
  5. Bioenergy, climate change, & sustainability education

Ongoing projects and research activities intend to determine agronomic application rates of lime-stabilized biosolids and poultry litter, to produce, upgrade, and utilize organic waste-derived biochar and pyrolysis bio-oil on farm, to develop biochar-formulated filtration media for treating stormwater, and to train science educators with bioenergy, bioproducts and climate change literacy.
