-In 1996, the USDA-Natural Resources Conservation Service (NRCS) Jamie L. Whitten Plant Materials Center (PMC) released three locally collected, source identified wetland plants. Indian Bayou source powdery thalia (Thalia dealbata Fraser ex Roscoe) and Leflore source creeping burhead [Echinodorus cordifolius (L.) Griseb.] were collected in the Mississippi Delta and Leaf River source woolgrass [...

Due t o the on-board signal processing used by NSCAT, the Gaussian distribution model f o r the power measuremeiits used in the wind retrieval algorithm i s only a n approximation t o the actual distribution. Working from first principles and the design of the N S C A T signal processor we derive the distribution of the NSCAT measurements as a function of the normalized radar cross section, NRC...

The Blue-winged Warbler (Vermivora cyanoptera) is a songbird that breeds in eastern deciduous forests of North America. species declining, partially due to declines forest disturbances. According the umbrella concept, management actions implemented benefit other critically declining disturbance-dependent like Cerulean (Setophaga cerulea) and Golden-winged chrysoptera) war...

s of papers 47 follow manner. Rules for Animal Feeding Operations have been recently enforced and will require adoption of appropriate Best Management Practices (BMP’s), which includes Nutrient Management Planning for all operations where animals are raised in confinement according to regulatory definition. Nutrient management is necessary for agricultural production systems to protect air, soi...

This paper is aimed at analyzing the electromagnetic (EM) scattering from the twodimensional (2-D) Gaussian rough surfaces characterized by textures. Visual appearances of the stripe texture can be generated through the angle rotating in Fourier transform when the ratio of the correlation lengths in two directions is large enough. The scattering field is derived in Cartesian coordinate system t...

and Agriculture (NIFA) and Natural Resource Conservation Service (NRCS) to evaluate the effects of agricultural conservation practices on spatial patterns and trends in water quality at the watershed scale. In some projects, participants also investigated how social and economic factors influence implementation and maintenance of practices. The 13 projects were conducted from 2004 to 2011 as pa...

Extensive data used to quantify broad soil C changes (without information about causation), coupled with intensive data used for attribution of changes to specific management practices, could form the basis of an efficient national grassland soil C monitoring network. Based on variability of extensive (USDA/NRCS pedon database) and intensive field-level soil C data, we evaluated the efficacy of...

Starting with premises about the role of tacit knowledge, communities of practice, and ICT mindtools in efficacious learning and teaching, we make some predictions about the interrelationship of these processes. These relationships are explored with secondary analysis of SITES M2 data. Specifically, cases selected as "stellar" by NRCs in 21 countries are re-analyzed. Findings confirm that to th...

The Maumee River watershed is the largest drainage basin that discharges into the Great Lakes. Although the watershed is largely a rural landscape, several major urban-industrial cities, including Fort Wayne and Toledo are located along the river. Many water quality concerns are present, especially nonpoint rural runoff that contributes significant amounts of sediment into the Maumee River. The...
