InvestigatorClimate Change Impacts Phosphorus Loss From Tile-Drained Farm Fields
More frequent severe drought and heavy rain events can lead to spikes in phosphorus export from tile drains in Vermont farm fields.
InvestigatorLong-term Soil Monitoring Program Established to Detect Environmental Change
A 100-year+ study monitoring soil in Vermont forests completed the first 15 years of sampling and detected small changes in soil chemistry over time.
InvestigatorEarthworms and Elevation Affect Soil Carbon in Vermont Forests
Study of soil carbon in forest plots reveals complex interaction among land-use history, earthworms, soil chemistry, and tree species.
InvestigatorComparing Soil and Stream Phosphorus Among Farms, Wetlands and Forests in Vermont
In the Missisquoi River basin, soils in agricultural lands and adjacent streambanks have more phosphorus than soils in forests and their streambanks.
InvestigatorEarthworms in Forest Soils: The Bad and the Not So Bad
Earthworms in forests make soils inhospitable for many tree seedlings and understory plants, but they may help to store carbon deep in the mineral soi
InvestigatorUsing Digital Soil Maps to Predict Risks of Phosphorus in Riparian Buffers
Predicting Risks in Riparian Buffers or Digital Soil Maps as Risk Management Tool Study assesses the usefulness of digital soil maps as a management t
InvestigatorNot All Forms of Stream Bank Phosphorus Lead to Algal Blooms
Investigation of Chittenden County streams reveals surprisingly low amounts of bioavailable phosphorus coming from stream banks.
