Climate Change Impacts on Yields and Soil Carbon in Row Crop Dryland Agriculture.

Dryland agroecosystems could be a sizable sink for atmospheric carbon (C) due to their spatial extent and level of degradation, providing climate change mitigation. We examined productivity and soil C dynamics under two climate change scenarios (moderate warming, representative concentration pathway [RCP] 4.5; and high warming, RCP 8.

Soil Carbon Pools in Dryland Agroecosystems as Affected by Several Years of Drought.

No-till and increased cropping intensity (CI) can increase yield and soil organic C (SOC) in the US Great Plains compared with traditional wheat ( L.)-fallow management. However, gains in SOC and other C pools may not be permanent.

Measuring and Mapping Patterns of Soil Erosion and Deposition Related to Soil Carbonate Concentrations Under Agricultural Management.

Spatial patterns of soil erosion and deposition can be inferred from differences in ground elevation mapped at appropriate time increments. Such changes in elevation are related to changes in near-surface soil carbonate (CaCO3) profiles. The objective is to describe a simple conceptual model and detailed protocol for repeatable field and laboratory measurements of these quantities.

Community-Academic Partnership to Investigate Low Birth Weight Deliveries and Improve Maternal and Infant Outcomes at a Baltimore City Hospital.

Purpose Mercy Medical Center (MMC), a community hospital in Baltimore Maryland, has undertaken a community initiative to reduce low birth weight (LBW) deliveries by 10 % in 3 years. MMC partnered with a School of Public Health to evaluate characteristics associated with LBW deliveries and formulate collaborations with obstetricians and community services to improve birth outcomes. Description As part of the initiative, a case control study of LBW was undertaken of all newborns weighing <2500 grams during June 2010-June 2011 matched 2:1 with newborns ≥2500 grams (n = 862).
