McDaniel, M. D., J. A. Bird, J. Pett-Ridge, E. Marin-Spiotta, T. M. Schmidt, and A. S. Grandy. 2022. Data from: Diversifying and perennializing plants in agroecosystems alters retention of new C and N from crop residues. Iowa State University doi: 10.25380/iastate.21259206.v1

These data are soil, CO2 efflux, dissolved organic carbon leaching, and various other measures from a mesocosm experiment performed in long-term (12-years) crop diversity experiment near Hickory Corners, MI, United States.Briefly, we tracked dual-labelled (13C and 15N), isotopically enriched wheat (Triticum aestivum) residue in situ for two years as it decomposed in three agroecosystems: maize-soybean rotation (CS), maize-soybean-wheat plus red clover and cereal rye cover crops (CSW2), and spring fallow management with regeneration of natural grassland species (7-10 species; SF). We measured losses of wheat residue (Cwheat and Nwheat) in leached soil solution and greenhouse gas fluxes, as well as how much was recovered in microbial biomass and bulk soil at 5-cm increments down to 20 cm.
