Data from: Soil carbon and nitrogen data during eight years of cover crop and compost treatments in organic vegetable production

This article includes the raw data, descriptive data (means) and inferential statistics (95% confidence intervals) on the effects of compost and cover cropping over an 8 year period in the Salinas Organic Cropping Systems (SOCS) experiment including: (1) changes in soil total organic C and total N concentrations and stocks and nitrate N (NO3-N) concentrations over 8 years, (2) cumulative above ground and estimated below ground C and N inputs, cover crop and crop N uptake, and harvested crop N export over 8 years, (3) soil permanganate oxidizable carbon (POX-C) concentrations and stocks at time 0, 6 and 8 years, and (4) cumulative, estimated yields of lettuce and broccoli (using total biomass and harvest index values) over the 8 years.

Patterns of precipitation and productivity on various topographic positions on the Central Plains Experimental Range, Nunn, Colorado

Thirty-six years of aboveground net primary productivity (ANPP) data collected across a topographic sequence and daily precipitation data from the semiarid shortgrass steppe of North America to examine patterns and drivers of spatiotemporal variability in ANPP.

Long-Term Agricultural Research (LTAR) network - Meteorological Station - Upper Mississippi River Basin - St. Paul

The United States Department of Agriculture - Agricultural Research Service (USDA-ARS) Soil and Water Management Research Unit established a meteorological data collection system at the Rosemount Research and Outreach Center in 2003. In 2015 the site became part of the Long-Term Agroecosystem Research (LTAR) network. The site is located in Dakota County Minnesota in the Upper Mississippi River Basin (UMRB) watershed. Data are recorded at 15-minute intervals

Soil Dynamics Research for Greenhouse gas Reduction through Agricultural Carbon Enhancement network in Auburn, Alabama

This study provides data on soil C and N dynamics and subsequent trace gas emissions at the landscape scale. Evaluates effects of landscape and soil management on 1) methane (CH4), nitrous oxide (N2O) and carbon dioxide (CO2) fluxes, 2) soil carbon (C) and nitrogen (N) mineralization and 3) cover crop decomposition and mineralization.

Walnut Gulch Experimental Watershed, Lucky Hills (Carbon Dioxide and Water Flux)

The meteorological data and Bowen ratio energy balance systems (BREB) (Model 023/CO2 Campbell Scientific Inc., Logan, Utah, USA) data are used to calculate carbon dioxide and evapotranspiration (ET) fluxes at Lucky Hills. The stored Bowen ration instrument data from the measurement site were transmitted by radio daily to our research station in Tombstone, AZ.
