Legacy effects of grassland management on soil carbon to depth.
The importance of managing land to optimize carbon sequestration for climate change mitigation is widely recognized, with grasslands being identified as having the potential to sequester additional carbon. However, most soil carbon inventories only consider surface soils, and most large-scale surveys group ecosystems into broad habitats without considering management intensity. Consequently, li...
متن کاملEffects of grassland conversion to croplands on soil organic carbon in the temperate Inner Mongolia.
This study investigated the effects of grassland conversion to croplands on soil organic carbon (SOC) in a typical grassland-dominated basin of the Inner Mongolia using direct field samplings. The results indicated that SOC contents decreased usually with increasing soil depth, with significant differences between the upper horizons (0-30cm) and the underlying horizons (30-100cm). Also, SOC den...
متن کاملCrop/Forage/Soil Management/Grassland Utilization
For the long-term sustainability of the dairy industry in the Northeastern USA, manure nutrient application rates should not exceed crop nutrient removal once aboveoptimum soil fertility levels are reached. Dairy producers have shown a growing interest in brown midrib (BMR) forage sorghum (Sorghum bicolor (L.) Moench.) · sudangrass (Sorghum sudanense Piper) hybrids (S · S) as a more environment...
متن کاملSoil Carbon, Nutrients, and Mycorrhizae during Conversion of Dry Tropical Forest to Grassland
Wildfires and alien grass invasion threaten dry tropical forests throughout Central America. Efforts to preserve and restore these forests will require a better understanding of how conversion to grassland changes key belowground processes and organisms such as soil organic matter, nutrient cycling, and mycorrhizae. We studied forest, edge, and grassland soils from five 60-m transects perpendic...
متن کاملSoil Carbon Pools in California’s Annual Grassland Ecosystems
Rangeland ecosystems cover approximately one-third of the land area in the United States and half of the land area of California. This large land area, coupled with the propensity of grasses to allocate a considerable proportion of their photosynthate belowground, leads to high soil carbon (C) sequestration potential. Annual grasslands typical of the Mediterranean climates of the western United...
