Land and pastoralism: New South Wales Riverina
The Riverina region in south-western New South Wales, Australia, is a discrete geographical area having unique patterns of soils and vegetation. During 170 years, it has been used productively for sheep and cattle grazing, but with significant detrimental impact on the natural systems. This article reviews the historical impact and suggests means of rehabilitating the landscape for the purposes ...

Reducing the impact of summer cattle grazing on water quality in the Sierra Nevada Mountains of California: a proposal
The Sierra Nevada Mountain range serves as an important source of drinking water for the State of California. However, summer cattle grazing on federal lands affects the overall water quality yield from this essential watershed as cattle manure is washed into the lakes and streams or directly deposited into these bodies of water. This organic pollution introduces harmful microorganisms and also ...

Costs of land use for conservation in Central Europe and future agricultural policy
In Germany and other countries of Central Europe, biodiversity in the rural countryside is best conserved by applying traditional land-use methods, such as low input sheep and cattle grazing. These are very uneconomical according to conventional accounting and can only be carried out at present by benefitting heavily from the subsidy schemes of the CAP. Trade liberalisation demands the abolition ...

Evaluation of cattle bedding and grazing BMPs in an agricultural watershed in Alberta
This paper highlights the environmental impacts of implementing beneficial management practices to address cattle bedding and direct access to the creek in a study watershed in southern Alberta, Canada. Approximately 35 cow–calf pairs grazed 194 ha of grass forage and had direct access to the creek in the spring and summer. During winter, the cattle were fed adjacent to the creek at an old ...

Examination of Salmonella and Escherichia Coli translocation from hog manure to forage, soil, and cattle grazed on the hog manure-treated pasture
Use of hog (Sus scrofa) manure as a fertilizer is a practical solution for waste re-utilization, however, it may serve as a vehicle for environmental and domestic animal contamination. Work was conducted to determine whether pathogens, naturally present in hog manure could be detected in cattle (Bos taurus) grazed on the manure-treated pasture, and whether forage contamination occurred. During ...

Weed biomass and species composition as affected by an integrated crop–livestock system
Crop and livestock production are rarely integrated together in modern farming systems. Reintegrating crops with livestock production has been shown to produce many agronomic and environmental benefits. The objective of this study was to evaluate how an integrated crop–livestock system would influence weed biomass and weed species composition compared with a conventional, continuous corn (Zea ...

Supplementation strategies effects on performance of beef heifers grazing stockpiled pastures
The increased cost of inputs has led livestock producers in the southeastern United States to use alternative management practices to supplement beef cattle (Bos spp.) on pastures. The objective of this study was to evaluate the performance of beef heifers grazing stockpiled limpograss [Hemarthria altissima (Poir.) Stapf & C.E. Hubb.] pastures supplemented with cottonseed meal (CSM, Gossypium ...

Grazing effects on yield and quality of hard red and hard white winter wheat
Six hard red (2137, Jagalene, Jagger, OK101, Stanton, and Thunderbolt) and six hard white (Burchett, Lakin, NuFrontier, NuHills, NuHorizon, and Trego) winter wheat (Triticum aestivum L.) varieties were evaluated for grain yield and quality in southwestern Kansas in 2004 and 2005. Cattle commonly graze wheat in this region from late November to mid March in a dual-purpose system. The experimental ...

Cattle gain and crop yield for a dryland wheat-sorghum-fallow rotation
Increasing pumping costs and declining well capacities in the U.S. Southern High Plains have led to greater reliance on less productive and inherently riskier dryland cropping systems. Dryland wheat (Triticum aestivum L.) and grain sorghum [Sorghum bicolor (L.) Moench] are typically grown in a 3-yr wheat-sorghum-fallow (WSF) rotation that may be intensified by integrating cattle (Bos taurus) ...

Making Animal Feed Pellets From Hay
Hay refers to dried grass used as livestock fodder. It is fed to especially pasturing animals, for instance, sheep, goats, horses and cattle when grazing is unobtainable due to harsh climatic conditions. Pellets are renewable organic matter made from compressed hay and other biomass, pellets are used to balance the nutrition for grazing animals. Also, the pellets are very nutritious and easy to ...

Why are we monitoring nutrients at different depths?
Recently, LG Sonic introduced the MPC-Lab, an innovative monitoring buoy that can monitor algae, physico-chemical variables, and even nutrients such as nitrogen and phosphorus in near real-time and at different depths in a body of water. Combined with our other monitoring tools, this system offers a unique way to detect the spatial and temporal patterns of nutrient concentrations which play a ...

Can Latin America do palm oil right?
As western hemisphere oil palm plantations boom, environmentalists eye ways to avoid repeating the devastation in Southeast Asia. What do soap, Ben & Jerry’s and Kit Kat bars have in common? They all contain palm oil — produced by the oil palm tree. Native to West Africa, oil palm has been planted throughout the tropics to provide a source of this increasingly in-demand ...

Simulating gross primary productivity of humid-temperate pastures
Although most pasture growth models simulate many above- and belowground components of the plant community, calibration and validation are usually based only on periodic measurements of aboveground forage yield. This research used daily measurements of gross primary productivity (GPP) to validate the photosynthesis subroutine of the Integrated Farm System Model (IFSM). The model was calibrated ...

Tillage requirements for integrating winter-annual grazing in peanut production: plant water status and productivity
The use of crop rotation systems involving winter-annual grazing can help peanut (Arachis hypogaea L.) producers increase profitability, although winter-annual grazing could result in excessive soil compaction, which can severely limit yields. We conducted a 3-yr field study on a Dothan loamy sand in southeastern Alabama to develop a conservation tillage system for integrating peanut with ...

Soil seed bank composition in pastures of diverse mixtures of temperate forages
Seed banks may contribute useful or weedy species that fill gaps in pastures. In a previous study, pastures planted to complex mixtures of forages had a lesser proportion of weedy species in the aboveground vegetation. In this study, we relate changes in the species composition of the seed bank to changes in the aboveground vegetation. In August 2001, four mixtures [two, three, six, and nine ...

How a new way of thinking about soil sparked a national movement in agriculture
For three weeks every month, Ray Archuleta captivates audiences with a few handfuls of soil. He begins with two clumps, dropping them into water. The soil from a farm where the soil isn’t tilled holds together, while the tilled soil immediately disperses, indicating poor soil structure. Next, volunteers from the audience — mostly farmers and ranchers — pour water over a soil ...
