Data quantifying intersee de d cover crops effects on soil water and corn productivity in corn-soybean-wheat no-till cropping systems

The data described support the research article entitled "In-terseeded cover crop mixtures influence soil water storage dur-ing the corn phase of corn-soybean-wheat no-till cropping sys-tems ". Data were collected during the corn (Zea mays L.) phase from rotations with four different cover crop (CC) treatments. The study was conducted at the USDA research facility in Beltsville, MD from 2017 through 2020. The data are available from a repository at Ag Data Commons. Descrip-tions of crop rotations, soil water and temperature sensors, placement, and frequency of measurements are provided in the manuscript and repository. Hourly volumetric soil wa-ter content (m( 3) m( -3)) (VWC) and soil temperature ( C-degrees) data for each soil depth (0-12, 25-35, 50-60, 75-85 cm) are avail-able from the repository. In the manuscript, daily values of soil water storage were used to estimate daily evapotran-spiration (ET) and infiltration. A text file of meta informa-tion is provided in the repository describing data collection procedures, estimation of ET and infiltration, and methods used to replace sensor data having errors. Daily precipita-tion, maximum and minimum temperatures, net solar radi-ation, and windspeed collected at a nearby weather station are provided for estimating growing degree days and poten-tial ET. Cover crop biomass (kg ha( -1)) prior to corn planting and corn yields are provided by replication and cover crop system treatment for the four years.Published by Elsevier Inc.
