Determination of Optimal Cropping System for White-tailed Deer in the Southeast and Chufa Response to Nutrient Additions
(2011-04-08)
White-tailed deer (Odocoileus virginuanus) are an economically important wildlife resource in the Southeast. A significant portion of expenditures related to white-tailed deer goes towards food plot production and management, ...
Development of Fertilizer Recommendations for Native Biofuel Crops and Nutrient Release from Cattle Feces
(2010-11-10)
Plant biomass is a viable raw material for renewable energy production. The use of perennial grasses is a possible option, however information on their nutrient management in the southeastern U.S. is deficient. The ...
Different Approaches for Improvement of Nitrogen Management in Alabama Corn Grain Production
(2013-07-19)
Nitrogen (N) fertilization management in corn (Zea mays L.) production requires more consideration in Alabama. This is due to high spatial variability in soil texture across the state and within fields, and to the high ...
Effect of Land-applied Arsenicals on the Soils of Alabama
(2010-08-03)
Many agricultural practices apply arsenicals directly to land through agricultural practices. Over time, repeated land-application of arsenicals may result in accumulation of arsenic in the soil. This may be problematic ...
Effect of Rye Residue on Soil Properties and Nitrogen Fertilization of Cotton
(2008-08-15)
Conservation tillage systems that use rye (Secale cereale L.) as a cover crop have many benefits on soils properties and crop productivity. However, rye biomass could be harvested for alternative uses, which could jeopardize ...
Effect of Shade, Irrigation and Nutrients on Dry Matter Yield and Flavonoid Content of American Skullcap
(2009-04-16)
Growing interest in medicinal herbs results in a need to domesticate medicinal
plants traditionally harvested in the wild. American skullcap (Scutellaria lateriflora),
native to moist habitats in eastern North America, ...
Effect of Weed Management on Fruiting Position and Yield of RoundUp Ready Flex Cotton
(2006-08-15)
Roundup Ready Flex cotton was commercially available in 2006 and growers need production information about this new technology. Field trials were conducted at the Prattville Experiment Field, Prattville, AL and the Field ...
Effects and Sustainability of Clover Inclusion within Warm-Season Turf Swards
(2013-10-28)
Efforts to decrease supplemental nitrogen (N) applications to turfgrass justify alternative fertility strategies such as legume inclusion. Legumes such as clovers (Trifolium spp.) are present within many turfgrass scenarios. ...
Effects of Sorption and Desorption on Bioavailability of Atrazine in Soils Amended with Crop Residue Derived Char
(2006-08-15)
The bioavailability of pesticides in soils is affected by the addition of crop residue-derived char, which alters the sorption and desorption characteristics of the soil. Sorption, desorption and bioavailability experiments ...
Effects of Subsurface Drip Irrigation on Chemical Soil Properties and Cotton Yield
(2009-04-22)
Subsurface drip irrigation (SDI) has proven to be an economical method of irrigation for agronomic row crops. It is suitable for small irregular shaped fields and has the highest water use efficiency of any other irrigation ...
Evaluation of a New Sunn Hemp (Crotalaria juncea L.) Cultivar in Alabama
(2010-12-07)
The southeastern region of the U.S. is often characterized by soils with low innate fertility exacerbated by a history of tillage. Nitrogen (N) is an important and limiting soil nutrient applied to fields to maximize crop ...
Evaluation of best management practices for bermudagrass (Cynodon spp.) control in zoysiagrass (Zoysia spp.) turf
(2010-04-07)
Zoysiagrasses (Zoysia spp.) are a popular choice as turfgrasses in the transition zone of the United States. When managing zoysiagrass, one of the most problematic weeds to control is bermudagrass [Cynodon dactylon (L.) ...
Evaluation of Black Oat (Avena strigosa schreb.) Germplasm
(2007-12-15)
Black oat has become an important winter cover crop in subtropical and temperate regions. Originating in the northern parts of Spain and Portugal, black oat cultivation has spread to different parts of the globe. Even ...
Evaluation of EPTC as a Preplant Soil Treatment in Warm-Season Sod Production
(2011-04-21)
Field research was conducted at Auburn University Turfgrass Research Unit (AUTRU) Auburn AL, during 2008 to 2010 and Gulf Coast Research and Extension Center (GCREC) Fairhope AL in 2009, to evaluate EPTC as a preplant soil ...
Evaluation of Progress in Annual Ryegrass (Lolium Multiflorum Lam.) Selected for Increased Winter Productivity
(2014-04-25)
Forage availability in the southeastern USA is limited during winter and supplemental feeding increases management costs. Therefore, development of a suitable cultivar with increased winter productivity would be a valuable ...
Evaluation of Selected Cellulosic Energy Crops for the Southeastern United States
(2012-12-05)
Encouraging progress towards commercial production of cellulosic biofuels has recently raised the importance of identifying economically feasible and environmentally sustainable cellulosic biomass supply chains. In this ...
