Nutrient Cycling Budgets in Managed Pastures ecosystems where the dominant vegetation component is comprised of herbaceous species, with less than 10% tree cover (Jones and Donnelly 2004). Grasslands are either natural vegetation (e.g. the steppes of central Asia and prairies of North America) or anthropogenic in origin (e.g. north-western an

Natural Grasslands — a Case Study in Greecee warm months. Optimal moisture and temperature optima often do not coincide, although there are numerous spatial and temporal variations. The topography, soils and vegetation of the Mediterranean areas are also variable. Most of the area is covered by hills and mountains, resulting in a very rugged

The United Nations Educational, Scientific and Cultural Organization (UNESCO 1979) proposed the following classification scheme for drylands: hyper-arid zone (P/ET <0.03), arid zone (P/ET 0.03–0.20), semi-arid zone (P/ET 0.20–0.

Nutrient Cycling in the Tundragions of high latitude north or south of the tree line (i.e. arctic/Antarctic or polar tundra), or high altitude belts above the natural tree line in all climatic zones (i.e. alpine tundra). Arctic and alpine tundras have many similarities, but also great differences. This chapter describes the proc

Nutrient Cycling in Forests and Heathlands: an Ecosystem Perspective from the Water-Limited SouthFor example, there have been numerous major projects, conferences and meetings focused on nutrient cycling in forests since 1990 (e.g. Boyle and Powers 2001; Nilsson et al. 1995; Schultze et al. 2000). These compendia are complemented by nutrient cycling contributions to more broadly based meetings
