Residential lawn lysimeter nutrient leaching data

Residential lawn management often includes fertilizer application to encourage healthy plant growth and support the aesthetic preferences of homeowners and communities. These inputs may negatively impact the environment by increasing nutrient export to aquatic ecosystems via surface runoff or leaching through soil into groundwater. Fertilizer management and nutrient export are of particular concern in karst areas like North-Central Florida, where the underlying karst geology leads to rapid, direct connections between surface and groundwater ecosystems. We quantified nitrogen (N) and phosphorus (P) leaching from residential landscapes in North-Central Florida. We investigated nutrient leaching from landscapes spanning a real estate gradient and across different fertility treatments (no N fertilizer, synthetic mineral fertilizer, biosolids-based organic mineral fertilizer, compost topdressing, and natural areas). We measured leachate from these landscapes weekly for one year. All resident..., , , # Residential lawn lysimeter nutrient leaching data

## Description of the data and file structure

Groundwater leachate samples were collected from lysimeters installed in residential and natural areas in Alachua County, FL, USA. Residential landscapes were treated with different fertilizer treatments as described in the Reisinger et al. manuscript accepted in the Journal of Environmental Quality (DOI: 101002/jeq2.20657). Samples were collected from lysimeters weekly and analyzed for total leachate volume and various forms of nitrogen and phosphorus. Samples were then analyzed to test for the effects of treatment and time on the continuous and cumulative nutrient-leaching loads. We also collected soil chemistry data and property value data (from Zillow.com) as potential predictors of nutrient leaching.
