Maintaining ground cover of forages may reduce the export of nitrogen (N) from pastures. The objective of this work was to determine the effect of ground cover on N export from pastured riparian areas receiving simulated rainfall. Plots were established on two adjacent sites in the North Carolina Piedmont: one of 10% slope with Appling sandy loam soils and a second of 20% slope with Wedowee san...

Seed dispersal is a fundamental process in plant ecology and is of critical importance for the restoration of tropical communities. The lands of the Cabo Rojo National Wildlife Refuge (CRNWR), formerly under agriculture, were abandoned in the 1970s and colonized mainly by non-native tree species of degraded pastures. Here we described the seed rain under the most common native and non-native tr...

Thirty-two groups of six sheep, classified into three breed categories according to their weight class (L: light, one breed (n=7); M: medium light, two breeds (n=10); H: heavy, three breeds (n=15)) were tested for antipredatory behaviour towards seven stimulus regimes. Tests were performed on 2-5-years-old ewes with lambs inside standardised and fenced home pastures. Stimulus regimes were: man ...

Pastures require year-round access to water and in some locations rely on irrigation during dry periods. Currently, there is a dearth of knowledge about the potential for using mitigate N2O emissions. This study aimed losses from intensely managed pastures by adjusting frequency soil gas diffusivity (Dp/Do) thresholds. Two regimes were compared; standard treatment based farmer practice (15 mm a...

Restoration of grasslands dominated by tall fescue (Schedonorus phoenix [Scop.] Holub) to native tallgrass prairie usually requires burning, herbicides, or reseeding. We tested seasonal grazing by livestock in winter, combined with cessation of fertilization, as a restoration tool for modifying the competitive dynamics among herbaceous plants to restore tallgrass prairie communities in southeas...

pastures play an important role in protecting environment and ecosystems. unfortunately more than 40 percent of pasturess in the world have been destroyed and 20 percent of destroyed pastures are located in developing countries. application of solar energy could significantly contribute to preserving the pastures. the main purpose of this study was to examine the role of solar energy in protect...

The nonergot alkaloid-producing endo-phyte, AR542, has been shown to improve the persistence and yield of tall fescue pastures without causing the animal disorders commonly associated with tall fescue toxicosis. A 3-yr grazing study was conducted to compare effects of AR542-infected tall fescue pastures with wild type endophyte-infected (E+) tall fescue pastures on cow-calf performance. Replica...

The pasture and animal productivity of established high producing pastures in the Waikato has been compared with newly sown pastures based on recently released herbage cultivars. The established pastures were a mixture of Nui perennial ryegrass, Paspalum dilatatum and Htiia white clover. The new cultivars tested were Ellett perennial ryegrass, Wana cocksfoot and Roa tall fescue, each sown with ...
