Utilization of Biosolids for Pasture Fertilization
Biosolids are solid, semi-solid, or liquid materials resulting from the treatment of domestic sewage sludge. The term “biosolids” was introduced by the wastewater treatment industry in the early 1990’s and has been adopted by the United States Environmental Protection Agency (U.S. EPA) to distinguish high quality, treated sewage sludge from raw sewage sludge and from sewage sludge containing la...
متن کاملSmooth bromegrass pasture beef growing systems: Fertilization strategies and economic analysis
In recent years, prices for N fertilizer have increased dramatically, reducing net returns of fertilized pasture systems. A 5-yr study from 2005 to 2009 was conducted to evaluate management strategies and relative differences in profitability for 3 methods of backgrounding calves on smooth bromegrass pastures. Forty-five steers were used each year for a total of 225 animals in a randomized comp...
متن کاملEffects of stocking and nitrogen fertilization rates on steers grazing dallisgrass-dominated pasture.
To compare the performance of steer calves managed under different stocking rates (SR; 3.7, 6.2, 8.6, and 11.1 steers/ha for 140 d; chi(I1)) and N fertilization rates (112, 224, and 336 kg of N/ha; chi(I2)) in May 1996, 1997, and 1998, 72 steer calves (BW = 231 +/- 2.5 kg) were assigned randomly to one of 12 0.81-ha dallisgrass (51%)/common bermudagrass (32%) pastures. One-third of the fertiliz...
متن کاملPasture type and fertilization effects on soil chemical properties and nutrient redistribution
Chen, W., McCaughey, W. P., Grant, C. A. and Bailey, L. D. 2001. Pasture type and fertilization effects on soil chemical properties and nutrient redistribution. Can. J. Soil Sci. 81: 395–404. Soil samples were collected from beef pastures varying in species composition and fertilizer inputs after being grazed by cow-calf pairs for 4 yr (1995–1998) near Brandon, Manitoba. The objective of this e...
متن کاملFertilization results in increased tyrosine phosphorylation of egg proteins.
The sea urchin egg contains one or more tyrosine-specific protein kinase(s) which are active during the response of the egg to sperm fusion. Fertilization results in an 8-fold increase in the relative incorporation of [32P]orthophosphate into phosphotyrosine as compared to phosphoserine and phosphothreonine. Under defined in vitro conditions, plasma membranes from fertilized eggs incorporated 5...
