The Williamson River Basin, located in south-central Oregon, has a drainage area of approximately 3,000 square miles. The Sprague River, which flows into the Williamson River Basin, has a drainage ...


2. Long-term Tillage and Crop Rotation Study, Nebraska [USDA.ARS.SWCRU.CropSysTrial2]
(adapted from Project Summary) PROBLEM: Soil and water conservation concerns have been and continue to be the major driving forces in agricultural production in the western Corn Belt. In addition, ...


3. Rotation and Nitrogen Fertilization Effects on Changes in Soil Carbon and Nitrogen [USDA0098]
The dataset consists of data resulting from an experimental study involving seven cropping systems (three monoculture, two 2-year, and two 4-year rotations) with three rates of N fertilizer. Data ...


4. Soil Organic Matter Network, Lancaster Rotation, Wisconsin, USDA-ARS and University of Wisconsin [USDA.ARS.CPSWPRC.Lancaster]
The Lancaster Rotation, Wisconsin, legume cereal rotation began in 1967. The area is characterized by rolling to hilly landscapes, with soil developed in loess deposits of variable thickness over ...


5. Crop Residue Decomposition as Affected by Soil Erosion and Tillage, USDA-ARS [USDA.ARS.CPCRC.ResidueDecomp]
This data set is a result of a study to determine the rates of different crop residue decomposition (clover and wheat), under two different cropping regimes (grain sorghum plots with: no till and ...


6. Tillage, N Fertilization, and Crop Rotation Effects On Soil Organic C and N [USDA.ARS.SPNRU.tillNCropOM]
