Fig. 2From: Building houses and managing lawns could limit yard soil carbon for centuriesMean soil carbon and nitrogen pools (± SE) by depth and summed to 60-cm, across yard (n = 20; n = 16, 40–60 and 0–60 cm), field (n = 13), and forest (n = 12) uses comprising a use-intensity gradient within clusters (n = 12). Each land-use site is represented by three soil cores. Letters indicate differences of least-square means that adjust for site-specific pre-development legacies. Yard and field soil C and N pools were significantly different to 40-cm and marginally to 60-cm depth (p < 0.10)Back to article page
