Nitrogen Fertilization of Wheat No-Till Planted in Alfalfa Stubble
The N available after legumes is sufficient for maximum crop yields in many cropping systems. Fertilizing without accounting for the "extra" N mineralized from legume residues can contribute to high nitrate-N concentrations in the soil during crop production and increase nitrate-N leaching potential. Tillage practices also affect the physical, biological, and chemical nature of the soil, changi...
متن کاملMineral Concentrations of Annual Cool Season Pasture Forages in North Florida during the Winter-Spring Grazing Season: II. Trace Minerals
Concentrations of selected trace minerals (Cu, Fe, Zn, Mn, Co, Se) were determined from annual cool-season grass pasture forages over four consecutive winter-spring grazing seasons (2001-2005). Twice monthly forage samples were taken from eight experimental pastures used in beef cattle grazing trials. Two, 2-yr experiments were conducted; animal and pasture data were reported previously. Each e...
متن کاملMineral Concentrations of Cool-Season Pasture Forages in North Florida during the Winter-Spring Grazing Season: I. Macro Minerals
Concentrations of selected macro minerals (Ca, P, Na, K, and Mg) were determined from coolseason annual grass pasture forages over four consecutive late fall-winter-spring grazing seasons (2001-2005). Forage samples were taken from eight experimental pastures used in beef cattle grazing trials. Two, 2-yr experiments were conducted; animal and pasture data were reported previously (Myer and Blou...
متن کاملCool Season Annual and Perennial Grass Forages for California – a New Perspective
There is an increase in awareness of the benefits of grass hay from an agronomic and nutritional perspective. The main cool season forage grass species adaptable to California are annual ryegrass, Italian ryegrass, perennial ryegrass, orchard grass and tall fescue. The main characteristics of these species along with attributes of different varieties are highlighted in this paper. The agronomic...
