Pasture management can be effective at sequestering soil organic C. We determined the depth distribution of particulate organic C (POC), non-particulate organic C (NPOC), particulate-to-total organic C (POC-to-TOC) ratio, and particulate organic C-to-N (POC-to-N) ratio under pastures near Watkinsville, GA, USA. POC was highly related with total organic C (TOC), but became an increasingly larger...

For 2 grazing seasons, effects of pasture size, stream access, and off-stream water on cow distribution relative to a stream were evaluated in six 12.1-ha cool-season grass pastures. Two pasture sizes (small [4.0 ha] and large [12.1 ha]) with 3 management treatments (unrestricted stream access without off-stream water [U], unrestricted stream access with off-stream water [UW], and stream access...

THE ECOLOGY OF RAGWORT (SENECIO JACOBAEA L.) A REVIEW Summary: The available literature on ragwort is reviewed. The ecological behaviour of ragwort can be explained by its tendency to act as a colonising plant, which is encouraged by pasture disturbance. Ragwort-infested pasture and closed pasture alternate with each other, and this is influenced by a number of environmental and management fact...

Controversy has surrounded the possible differences in pasture production which result from grazing by cattle or sheep. Experiments conducted over the 1972-76 period show that pasture production under grazing by sheep is greater than under grazing by cattle under similar intensive managements. A change from sheep grazing to cattle grazing can cause a rapid deterioration in pasture production, w...

Grazing management is a key factor in pasture-based dairy systems, which can be improved given advanced knowledge of the effects of pregrazing pasture mass (PM) on the performance of dairy cows. The aim of this study was to quantify the effects of PM on the pasture intake, milk production, milk composition, and grazing behavior of strip- or rotational-grazing dairy cows, based on a meta-analysi...

To maintain a predominantly pasture-based system, the large herd milked by automatic milking rotary would be required to walk significant distances. Walking distances of greater than 1-km are associated with an increased incidence of undesirably long milking intervals and reduced milk yield. Complementary forages can be incorporated into pasture-based systems to lift total home grown feed in a ...

In breeding hind systems, summer is often a period when feed quality and quantity may compromise lactation in the hind and growth of the calf. The growth and feed intake of calves and hinds offered the leaf turnip Pasja were compared to those on a perennial pasture. Calves consumed 1.0 kg forage DM/head/d on pasture and 0.77 kg DM/d on Pasja. The higher digestibility of Pasja meant that the met...

Seasonal density of trichostrongylid nematode larvae was investigated on a pasture used for communal grazing of livestock, using standard procedure of pasture larval count. For this purpose, herbage samples were collected from a posture near Faisalabad at fortnightly intervals over a 12 month period from July 2000 to June 2001. The larvae of Haemonchus (H) contortus, Trichostrongylus species, O...

Dry matter production data for pure lucerne, overdrilled lucerne and pasture ark presented for 14 sites on pumice soils. On average, the annual dry matter yield of lucerne, harvested at early basal shoot movement, was 50% higher than from pasture, ranging froti 128% higher on a drought-prone soil where the pasture was dominant browntop to 33% on a more moisture-retentive soil type where the pas...
