InfiltraGon rde and sediment production were measured for 2 years on 3 pastures from an intensive rotational grazing system. The pastures were 32,24, and 16 ha in size. Stocking rate was held constant but stocking density at any given point in time varied due to pasture size. Stocking densities were 0.68,0.51, and 0.32 ha/AU, respectively. Within the respective treatments, midgrass interspa ces...

Mimosa pudica is the most abundant and problematic invasive species in tropical pastures. This study investigates the effects of two cattle grazing systems, long-term moderate grazing (LTG, 2.7 animal unit/ha/yr for 33 years) and short-term heavy grazing (STG, 5 animal unit/ha/yr for 2 years) compared with ungrazed exclosure pasture on the invasion of M. pudica and its relationship with herbage...

An experiment was performed during the grazing seasons of 1998, 1999 and 2000 to study the influence of the antiparasitic drug ivermectin and the nematophagous fungus Duddingtonia flagrans on cattle dung disintegration. The faeces originated from groups of animals that were part of a separate grazing experiment where different control strategies for nematode parasite infections were investigate...

al., 1994). Summed to 1-m depth, SOC content was not different between cropland and conservation reserve. Estimates of potential soil organic C (SOC) and total N (TN) In a shortgrass-steppe with 56 yr of grazing in Colorado, sequestration at depths below the traditional plow layer (i.e., 0–0.3 m) in agricultural systems are needed to improve our understanding of SOC was not different between un...

Proper grazing management practices can generate corresponding compensatory effects on plant community production, which may reduce inter-annual variability of productivity in some grassland ecosystems. However, it remains unclear how grazing influences plant community attributes and the variability of standing crop. We examined the effects of sheep grazing at four stocking rate treatments [con...

The aim of this study was to investigate the effects grazing on soil gross nitrification (GN) and denitrification (DN) rates environmental factors GN DN in desert grassland northern China. Soil samples were collected from July November 2017 March June 2018, with 5-5 taken three enclosures (CK) vs. heavy-grazing (G) randomized treatment blocks. We determined: (1) moisture (SM), pH, bulk density ...

The aim of this work is to investigate the feasibility of ion beam analysis techniques for monitoring swift heavy ion track formation. First, the use of the in situ Rutherford backscattering spectrometry in channeling mode to observe damage build-up in quartz SiO₂ after MeV heavy ion irradiation is demonstrated. Second, new results of the in situ grazing incidence time-of-flight elastic r...

water resources suitability is one of the most important factors to sustainabilityutilization of natural potential by rangeland grazing suitability. to determine this factor inshort time, low cost and high accuracy are most challenges of experts and ranchers. usingsuitable technique for this subject can be sustainable utilization comprising from rangelandecosystems according to its degradation ...

Moist high-altitude grasslands in South Africa are renowned for high avifaunal diversity and are priority areas for conservation. Conservation management of these areas conflicts with management for other uses, such as intensive livestock agriculture, which requires annual burning and leads to heavy grazing. Recently the area has become target for water storage schemes and renewable electricity...
