Three experiments were conducted to evaluate the influence of quality of
supplemental alfalfa quality on beef cattle consuming low-quality meadow grass (MG)
roughages. Fifteen steers (250 kg) were assigned randomly to one of three treatments: 1)
meadow grass (5.2% CP), no supplement (MNS); 2) meadow grass plus high quality
alfalfa...
The control of feral goats (Capra hircus) and relevant aspects of their biology were studied on Aldabra Atoll, Republic of Seychelles, from October 1993 - May 1994 and November 1994 - May 1995. A total of 832 goats were killed on Aldabra using both the Judas goat technique and traditional...
Seasonal trends in forage production and environmental parameters
for five plant community types within a northeastern Oregon riparian zone
were described and modeled using correlation and path analysis. Wet
meadows produced the greatest amount of herbage biomass, followed by moist
bluegrass meadows, gravel bars, forests and dry bluegrass meadows. Trends...
No-tillage winter wheat (Triticum aestivum L.) grown in a
wheat-fallow cropping system has consistently produced lower grain
yields than conventionally tilled soils in the semiarid Pacific
Northwest. A 2-year study was conducted in a long-term tillage trial
at Moro, OR to determine factors responsible for differences in wheat
growth and...
Human activities may contribute to the eutrophication of surface waters by
providing nutrients to aquatic ecosystems. Phosphorus is frequently identified as a
nutrient that is limiting to most aquatic ecosystems under natural conditions. Sources of
phosphorus contributing to eutrophic conditions often include nonpoint sources that are
dispersed across the landscape....
