Pasture degradation caused by overgrazing and inappropriate fertiliser management is a major production and environmental threat in Qinghai-Tibet Plateau. Previous research has focused on the effects of mixed nitrogen (N) and phosphorus (P) fertiliser and reduced grazing pressure on the plant community of the grassland; however, the role of P and how it interacts with various defoliation (the p...

Vegetation, seed rain, seed germination, microclimate, and soil physical and chemical parameters were measured in a recently abandoned pasture and adjacent primary rain forest in southern Costa Rica. The goal of this study was to assess the importance of these factors in limiting forest regeneration in abandoned pastures. Seed rain of animal dispersed species decreased dramatically in the pastu...

The proper management of soil, in order to improve ecosystem services, requires knowledge how different fractions carbon respond land use/land cover changes. This study aimed evaluate the responses total soil organic carbon, and its fractions, reforestation age use changes an Ultisol Posses catchment, a pilot area Brazilian program Payment for Environmental Services, located Southeastern Brazil...

The role of grassland ecosystems as net sinks or sources of greenhouse gases (GHGs) is limited by a paucity of information regarding management impacts on the flux of nitrous oxide (N(2)O) and methane (CH(4)). Furthermore, no long-term evaluation of net global warming potential (GWP) for grassland ecosystems in the northern Great Plains (NGP) of North America has been reported. Given this need,...

Feeding management deals with the provision of feed and forage that meet the nutrient requirements of the animals based on their stage of growth and physiological needs as well as the way in which they are fed. These two practices determine the success of an operation. The same is true when pastures are a primary source of nutrients. In this case, the producer’s skill in grazing management may ...
