Abstract Soil health can differ across cropping systems because of variation in edaphic and management factors. We evaluated how biological indicators soil (soil organic matter [SOM], permanganate oxidizable carbon [POXC], mineralizable [MinC], autoclaved‐citrate‐extractable [ACE] protein, potentially nitrogen [PMN]) compared four common Wisconsin systems: grazed cool‐season pastures, forage‐ba...

Within highway rights-of-way, native perennial grasses provide desirable services to support natural and human constructed ecosystems. However, native perennial grass establishment in annual grass dominated roadsides of semiarid and Mediterranean climates of the western United States requires specific cultural and chemical management treatments to control weeds. In 2004, field studies were cond...

The continuing clearance of native vegetation for pasture, and especially cropping, is a concern due to declines in soil organic C (SOC) and N, deteriorating soil health, and adverse environment impact such as increased emissions of major greenhouse gases (CO2, N2O and CH4). There is a need to quantify the rates of SOC and N budget changes, and the impact on greenhouse gas emissions from land u...

Rangeland degradation has been identified as a serious concern in alpine regions of western China on the Qinghai-Tibetan plateau (QTP). Numerous government-sponsored programs have been initiated, including many that feature long-term grazing prohibitions and some that call for eliminating pastoralism altogether. As well, government programs have long favored eliminating plateau pikas (Ochotona ...

The article provides information on the state of natural pastures and methods for improving degraded by overseeding perennial drought-resistant forage crops using resource-saving technologies adapted to conditions global climate change.

The daily BW gain of stocker steers grazing tall fescue [Lolium arundinaceum (Schreb.) S.J. Darbysh. = Schedonorus arundinaceus (Schreb.) Dumort.]-based pastures typically declines during summer. To avoid these declines, in part to mitigate the effects of tall fescue toxicosis, it is commonly advised to move cattle to warm-season forage during this period. A 3-yr (2006, 2007, and 2008) grazing ...

Reproductive wastage was investigated over two seasons in ten Merino flocks grazing pastures based on oestrogenic subterranean clover. Only 65 percent of ewes were served during the first 16 days of joining. Ovulation rates were low, averaging 1.13. Fertilization rates (73%) were low when compared with flocks unaffected by oestrogenic pastures. Embryonic mortality varied considerably between pr...
