Definitions

  • Cover Crop: a crop grown for the protection and enrichment of the soil

  • Reduced Tillage: practice of minimizing soil disturbance and allowing crop residue or stubble to remain on the ground instead of being incorporated into the soil

  • Buffer Strip: Conservation buffers are strips of permanent vegetation that are meant to intercept nutrients and sediment carried by surface water. They do that by slowing down surface water and allowing plants to take up and use the water and nutrients.

  • Bioreactors: Woodchip bioreactors are subsurface trenches filled with a carbon source, mainly wood chips, through which water is allowed to flow just before leaving a field to enter a surface water body.

  • Constructed Wetlands: Man-made systems engineered to approximate the water-cleansing process of natural wetlands. In agriculture, constructed wetlands are used to filter runoff from cropland, feedlots, aquaculture operations and agricultural processing facilities.
