Data from the analysis of nitrate as nitrogen in the soil and soil pore water within the vadose zone of a saturated riparian buffer (SRB). Additional properties measured include: Organic matter (as %), bulk density, moisture content, and porosity. Soil samples were collected pre-growing season (n=57) and post-growing season from two plots (n=29): vegetated plots and barren plots. Statistical comparison of among the treatments, Pre-growing season, plot with plants, and barren plot, and among the different depths, 30 cm, 60 cm, and 90 cm identified significantly different soil NO3--N concentrations. Plots with plants experienced a reduction in …

Nitrate Transport In The Unsaturated Zone, Patience Bosompemaa

Theses and Dissertations

Abundance of nitrate in the soil is a basic issue in agricultural land-use regions, causing eutrophication and pollution of water bodies. The study focuses on the role of a saturated buffer zone (SBZ) to remove nitrate from the groundwater resulting from agricultural activities. The study area is herbaceous SBZ located in central Illinois (40.614382ºN, -89.023542ºW), which lies between a stream and a farm located upgradient. The SBZ has been outfitted with an agricultural runoff treatment system that diverts tile drainage into the subsurface of the SBZ rather than discharging into the stream. Within the SBZ three experimental areas composed of …
