| Abstract
|
:
|
Residential ecosystems in the United States cover more area than any irrigated crop. In residential ecosystems—the places where people live—land users alter the retention of soil carbon (C) and nutrients, thereby affecting climate and water quality. Land users disturb soils, introduce biota, mow, and fertilize. These activities, in the past and present, affect soils in the future—a legacy—about which our knowledge is limited. To understand how land users’ belowground legacies alter environmental quality, I measured C and nutrients in soils and plants of 12 land-use clusters (yards, fields, forests) across exurban to rural parcels (> 0.4 ha) established 15-227 y. ago in the temperate forest (chapters 1, 3). Land uses within each land-use cluster had similar soil formation history prior to development. To understand how biotic introductions to residential lands contribute to land users’ soil legacies, I measured C, nutrients, and microclimate in 40 greenhouse-based turfgrass mesocosms with earthworms and/or woody plants (chapter 2).
