Assessment of a crop growth-water balance model for predicting maize growth and yield in a subtropical environment
Water Quality in Walnut Creek Watershed: Nitrate-Nitrogen in Soils, Subsurface Drainage Water, and Shallow Groundwater
Trend Analysis of Nutrient Concentrations and Loads in Surface Water in an Intensively Fertilized Watershed
Layer displays major crops in the contiguous US for 2011 at a 1 square mile spatial resolution. This dataset is a resampled subset of the 2011 Cropland Data Layer (CDL), 2011_30m_cdls.img, obtained from United States Department of Agriculture (USDA), National Agricultural Statistics Service (NASS). Acreage for corn, soybeans, cotton, and wheat was reclassified from the original 30 meter data and down-sampled to 1 square mile resolution for display on small-scale maps, such as those showing the extent of the lower 48 states. The purpose of the Cropland Data Layer Program is to use satellite imagery to (1) provide acreage estimates to the Agricultural Statistics Board for the state's major commodities and (2) produce...
FSA 10:1 NAIP Imagery m_3509834_ne_14_1_20150624_20150817 3.75 x 3.75 minute JPEG2000 from The National Map
This data set contains imagery from the National Agriculture Imagery Program (NAIP). The NAIP program is administered by USDA FSA and has been established to support two main FSA strategic goals centered on agricultural production. These are, increase stewardship of America's natural resources while enhancing the environment, and to ensure commodities are procured and distributed effectively and efficiently to increase food security. The NAIP program supports these goals by acquiring and providing ortho imagery that has been collected during the agricultural growing season in the U.S. The NAIP ortho imagery is tailored to meet FSA requirements and is a fundamental tool used to support FSA farm and conservation programs....
Agricultural chemical movement through a field-size watershed in Iowa: Subsurface hydrology and distribution of nitrate in groundwater
Yields of winter wheat, silage maize and grain maize in the main arable areas of the European Union (E.U.) were calculated with a simulation model, WOFOST, using historical weather data and average soil characteristics. The sensitivity of the model to individual weather variables was determined.Subsequent analyses were made using climate change scenarios with and without the direct effects of increased atmospheric CO 2. The impact of crop management in a changed climate was also assessed. The various climate change scenarios used appear to yield considerably different changes in yield, both for each location and for the E.U. as a whole.
