1. Aerating farmer stock peanut storage in the southeastern U.S

Author:
Butts, C.L.; Dorner, J.W.; Brown, S.L.; Arthur, F.H.

Subject:
stored products; peanuts; aeration; ventilation systems; agricultural structures and facilities; storage temperature; spatial variation; Arachis hypogaea; air flow; Georgia
Abstract:
... A two-year study was conducted to determine acceptable aeration strategies for farmer stock peanuts stored in conventional warehouses with and without headspace ventilation. Farmer stock peanuts were stored in 1/10th scale model warehouses with various aeration and ventilation treatments. Peanuts were loaded into each warehouse in the fall and stored for about 190 days. Peanuts stored with aeratio ...

2. Foliar deposition and off-target loss with different spray techniques in nursery applications

Author:
Zhu, H.; Derksen, R.C.; Guler, H.; Krause, C.R.; Ozkan, H.E.

Subject:
foliar spraying; plant nurseries; air-assisted sprayers; nozzles; spray drift; Malus domestica; spray deposition; agrochemicals; droplet size; droplet studies
Abstract:
... Information is lacking on spray techniques to improve deposit uniformity within nursery canopies and reduce off-target loss on the ground and via spray drift from the treated area. Spray deposits at various elevations within crabapple trees and on the ground were investigated with an air blast sprayer equipped with conventional hollow-cone nozzles, air-induction nozzles, and conventional hollow-co ...

3. Hydrologic evaluation of the Soil and Water Assessment Tool for a large tile-drained watershed in Iowa

Author:
Green, C.H.; Tomer, M.D.; Di Luzio, M.; Arnold, J.G.

Transactions of the ASAE 2006 v.49 no.2 pp. 413-422
ISSN:
0001-2351
Subject:
watershed hydrology; tile drainage; Soil and Water Assessment Tool model; Conservation Effects Assessment Project; subsurface drainage; agricultural watersheds; Iowa
Abstract:
... The presence of subsurface tile drainage systems can facilitate nutrient and pesticide transport, thereby contributing to environmental pollution. The Soil and Water Assessment Tool (SWAT) water quality model is designed to assess nonpoint and point source pollution and was recently modified for tile drainage. Over 25% of the nation's cropland required improved drainage. In this study, the model's ...

4. Hydrologic impacts of land-use changes in coastal plain watersheds

Author:
Bosch, D.D.; Sullivan, D.G.; Sheridan, J.M.

Transactions of the ASAE 2006 v.49 no.2 pp. 423-432
ISSN:
0001-2351
Subject:
land use change; stream flow; afforestation; forested watersheds; watershed hydrology; satellites; remote sensing; coastal plains; agricultural watersheds; Georgia
Abstract:
... Conservation programs developed and implemented by the USDA have led to land-use changes of large areas throughout the U.S. These changes in land-use may lead to changes in evapotranspiration and infiltration and subsequently to dramatic differences in hydrologic response. The impact of recent land-use changes was evaluated using observed precipitation and streamflow data from the Little River wat ...

5. Simulating water quality improvements in the Upper North Bosque River watershed due to phosphorus export through turfgrass sod

Author:

Subject:
water pollution; sediment yield; harvesting; water quality; sod strips; nitrogen; cattle manure; best management practices; erosion control; nonpoint source pollution; filter strips; Soil and Water Assessment Tool model; turf grasses; phosphorus; agricultural watersheds; Texas
Abstract:
... The Upper North Bosque River (UNBR) watershed is under a total maximum daily load (TMDL) mandate to reduce loading of soluble phosphorus (P) in impaired river segments. To address these problems, Texas A&M University researchers have developed a Best Management Practice (BMP) that removes excess nutrients from impaired watersheds through turfgrass sod. Harvest of manure-grown sod removes a thin la ...

6. Influence of summer management practices of grazed wheat pastures on runoff, sediment, and nutrient losses

Subject:
sediment yield; soil nutrients; grazing; cattle; agricultural runoff; fallow; nitrate nitrogen; losses from soil; Triticum aestivum; summer; legumes; winter wheat; phosphorus; Oklahoma
Abstract:
... The agricultural economy of the southern Great Plains relies on practices that incorporate grazed winter wheat and associated summer management practices. Information exists about the impact of these practices on water quality, but data related to runoff and associated nutrient and sediment movement due to high intensity, late summer storms in the southern Great Plains are limited. This study exam ...

7. Modeling long-term water quality impact of structural BMPs

Author:
Bracmort, K.S.; Arabi, M.; Frankenberger, J.R.; Engel, B.A.; Arnold, J.G.

best management practices; pollution control; nonpoint source pollution; soil nutrients; water erosion; erosion control; phosphorus; sediment yield; Soil and Water Assessment Tool model; long term experiments; water quality; water pollution; streams; agricultural runoff; Indiana
Abstract:
... Structural best management practices (BMPs) that reduce soil erosion and nutrient losses have been recommended and installed on agricultural land for years. A structural BMP is expected to be fully functional only for a limited period after installation, after which degradation of the BMP is likely to lead to a reduction in the water quality improvement provided by the BMP. Assessing the impact of ...
