Degraded pastures in Brazil: improving livestock production and forest restoration

Royal Society Open Science, 2021
Degraded pasture is a major liability in Brazilian agriculture, but restoration and recovery efforts could turn this area into a new frontier to both agricultural yield expansion and forest restoration.

Greenhouse Gas Emissions From Cropping and Grazed Pastures Are Similar: A Simulation Analysis in Australia

Frontiers in Sustainable Food Systems, 2020
The agricultural sector has potential to provide greenhouse gas (GHG) mitigation by sequestering soil organic carbon (SOC). Replacing cropland with permanent pasture is one practice promoted for its potential to sequester soil carbon.

Milk production, nitrogen utilization, and methane emission of dairy cows grazing grass, forb, and legume-based pastures.

Journal of Animal Science, 2020
Achieving high animal productivity without degrading the environment is the primary target in pasture based-dairy farming. This study investigated the effects of changing the forage base in spring from grass-clover pastures to forb or legume-based ...

Some challenges and opportunities for grazing dairy cows on temperate pastures

Grass and Forage Science, 2019
Grazing plays an important role in milk production in most regions of the world. In this review, some challenges to the grazing cow are discussed together with opportunities for future improvement.

Weed Management in New Zealand Pastures

Agronomy, 2019
In New Zealand, pastoral farming for dairy and meat production is the major land use. As with any agricultural production system, weeds are a threat to efficient pasture production in New Zealand.

Soil carbon stock and humification in pastures under different levels of intensification in Brazil

Scientia Agricola, 2019
Intensive management of tropical pastures has shown potential for greenhouse gas (GHG) mitigation due to high forage production and C accumulation in the soil.

Adequate vegetative cover decreases nitrous oxide emissions from cattle urine deposited in grazed pastures under rainy season conditions

Scientific Reports, 2019
A decline in pasture productivity is often associated with a reduction in vegetative cover. We hypothesize that nitrogen (N) in urine deposited by grazing cattle on degraded pastures, with low vegetative cover, is highly susceptible to losses.

Restoring Technology and a Seeding Unit for Recovering Mountain Meadow and Pasture Ecosystems

Сельскохозяйственные машины и технологии, 2023
The paper shows that the constant use of mountain meadows and pastures leads to soil degradation and herbage depletion. It is noted that grass overseeding on the sparse mountain grass meadows and pastures helps to increase their yield and nutritional ...

Challenges of beef cattle production from tropical pastures

Revista Brasileira de Zootecnia, 2018
The live weight gain of cattle on tropical pastures is reviewed and found to be low and dependent on the length of the growing season. Supplements may be added to address the primary limiting nutrient, which, in the dry season, is crude protein.

AMPUTATION REVISION IN AN ASIAN REHABILITATION CENTRE

Journal of Nepal Medical Association, 2004
A retrospective study was carried out of amputation revisions performed at Green Pastures Hospital and Rehabilitation Centre between Jan 1990 and April 2004. The purpose was to determine the reasons for revision and whether these were preventable, and as
