Tarp impacts on soil nitrate and soil moisture

These data demonstrate the impact of tarps on soil nitrate availability and soil moisture. We measured soil nitrate availability 2-3 days before and after tarp application and include the difference between these two time periods to show how tarps change soil nitrate availability. We additionally include here soil moisture measurements 3 weeks into the tarp application. <br> For more information, please refer to Kinnebrew et al. 2022 (https://doi.org/10.1080/21683565.2022.2146254) or contact Dr. Kinnebrew at [e-mail]. <br> Column Names and Explanations: <br> 1. Farm: the farm site (“A,” “B” or “C”) where the plot was located. All farms were located in Chittenden County, Vermont, USA <br> 2. Treatment: indicates the treatment type (silage tarps, clear plastic tarps, or control) <br> 3. Plot_Replicate: the treatment replicate number on each farm (1-6 for each treatment on each farm) <br> 4. Plot_ID: the unique identifier for each spatial plot <br> 5. Nitrate_PreTarping: nitrate availability (soil nitrate-N mg/kg) measured 2-3 days before tarp application (20 May 2021) <br> 6. Nitrate_PostTarping: nitrate availability (soil nitrate-N mg/kg) measured 2-3 days after tarp removal (23 June 2021) <br> 7. Nitrate_Change: Change in nitrate availability with tarping (soil nitrate-N mg/kg), calculated as post tarping minus pre tarping nitrate values <br> 8. Soil_Moisture: volumetric water content (%) of soil, measured with TDR soil probes on 16 June 2021
