Dry matter quality of above-ground biomass of abandoned grasslands

Policy Papers & Briefs
декабря, 2008
Slovakia

Chemical composition of 28 selected species of meadow herbs on the abandoned grassland was observed in a 3-year period of vegetation in the temperate locality with mainly cold winters of the central part of Slovakia (Strážov Hills, locality Chvojnica, elevation 600 m. From dicotyledonous plants there were analyzed 6 legumes and 16 other species, and from less significant grass species there were analyzed 6 species in the growth phase from the flower buds formation up to the flowering. The content of crude protein, fibre, and mineral nutrients (Ca, P, K, Mg, and Na) i.e.

agistment market in the northern Australian rangelands: failings and opportunities

Journal Articles & Books
декабря, 2008

Agistment is the practice of temporarily moving stock between properties, and is used by pastoralists both to strategically develop their enterprises and as a response to environmental heterogeneities such as variation in rainfall. This paper considers the agistment market in the northern Australian rangelands using the 'market failure framework'. This form of economic analysis identifies failings in a market, thus, provides a rigorous basis for designing interventions intended to improve market performance.

Long-term trends in streamflow from semiarid rangelands: uncovering drivers of change

Journal Articles & Books
декабря, 2008

In the last 100 years or so, desertification, degradation, and woody plant encroachment have altered huge tracts of semiarid rangelands. It is expected that the changes thus brought about significantly affect water balance in these regions; and in fact, at the headwater-catchment and smaller scales, such effects are reasonably well documented. For larger scales, however, there is surprisingly little documentation of hydrological change.

Categorising farming practices to design sustainable land-use management in mountain areas

Europe

In European mountain areas, shrub encroachment resulting from farmland abandonment is most often managed by mechanical operations such as roller chopping or controlled burning, which have proved to be ineffective and unsustainable. Recent agroecological findings highlight the potential impact of grazing on long-term shrub dynamics. We thus explored the potential contribution of livestock farms to the management of shrub encroachment.

Methods for improving rangelands in the Blacksea region of Turkey

Policy Papers & Briefs
декабря, 2008
Turkey

The objective of this study was to determine the most suitable method (or methods) to improve in the rangelands around Samsun-Turkey rangelands between 1993 and 1999. The 12 management treatments in this study included control, aeration, burning, herbicide application, fertilization, over-sowing, ploughing + resowing and a combination of all the treatments. A mixture of seeds consisting of alfalfa, sainfoin, smooth bromegrass, orchardgrass and blue wheatgrass was used for oversowing and in the ploughing + resowing plots.

Carbon accumulation and storage in semi-arid sagebrush steppe: Effects of long-term grazing exclusion

Journal Articles & Books
декабря, 2008

The potential of grazing lands to sequester carbon has been investigated in different terrestrial environments but the results are often inconclusive. Our study examined the soil organic carbon (SOC) and soil microbial biomass carbon (MBC) contents inside and outside four grazing exclosures that had been established more than four decades ago in the semi-arid sagebrush steppe of Wyoming.
