Soil‐Applied Atrazine Alters Blue Grama Physiology and Indirectly Influences Soil Nitrogen

Autor: Jack A. Morgan, W. D. Guenzi, M. C. Shoop, W. G. Knight

Publikováno v: Agronomy Journal. 85:1029-1035

Atrazine [2-chloro-4-(ethylamino)-6-(isopropylamino)-s-triazine] applied at sublethal concentrations to rangelands, has resulted in herbage production and/or enhanced plant N concentration of desirable warm-season grasses beyond that expected from we

Oxalate effects on solution phosphorus in a calcareous soil

Autor: Lynn M. Dudley, J. J. Jurinak, W. G. Knight

Publikováno v: Arid Soil Research and Rehabilitation. 6:11-20

Thermodynamics predict that in calcareous soils where the equilibrium activity of solution orthophosphate (P so) is controlled by any calcium‐phosphate mineral, calcium oxalate (CaC2O4) precipitation will increase P so by depressing Ca2+ ion activi

Growth and Physiological Responses of Greenhouse‐Grown Blue Grama to Atrazine

Autor: Jack A. Morgan, W. G. Knight

Publikováno v: Agronomy Journal. 83:677-683

Blue grama [Bouteloua gracilis (H.B.K.) Lag. ex Steud.] is an important native forage and the dominant C 4 species on the short-grass prairie. Sublethal concentrations of the herbicide atrazine (6-chloro-N-ethyl-N'-[1-methylethyl]-1,3,5-triazine-2,4-

Brief report: effects of pediatric HIV infection on mental and psychomotor development

Autor: W G, Knight, C A, Mellins, R L, Levenson, S M, Arpadi, R, Kairam

Publikováno v: Journal of pediatric psychology. 25(8)

To examine the effect of HIV status on infants' mental and psychomotor functioning, controlling for confounding factors such as prenatal drug exposure and birth conditions.Twenty HIV-infected and 25 seroreverted infants (ages 3-30 months old) were ad

Enhanced root system C-sink activity, water relations and aspects of nutrient acquisition in mycotrophic Bouteloua gracilis subjected to CO2 enrichment

Autor: H. W. Hunt, Jack A. Morgan, Lynn M. Dudley, W. G. Knight

Publikováno v: Belowground Responses to Rising Atmospheric CO2: Implications for Plants, Soil Biota, and Ecosystem Processes ISBN: 9789048144150

In order to better elucidate fixed-C partitioning, nutrient acquisition and water relations of prairie grasses under elevated [CO2], we grew the C4 grass Bouteloua gracilis (H.B.K.) lag ex Steud. from seed in soil-packed, column-lysimeters in two gro
