Vast dryland regions around the world are affected by the encroachment of woody vegetation, with important environmental and economical implications. Grassland-to-shrubland conversions are often triggered by disturbance of grassland vegetation, and the consequent formation of barren areas prone to erosion-induced nutrient losses. Inhibition of encroachment by erosion-induced depletion of soil n...

Plant life and food production for human closely depend on fertile and healthy soil. Knowledge about qualitative properties of soil and its potential production can contribute us in the plantation, fertilization, utilization and land management. In addition, Rangelands cover a very large portion of the earth's surface and play an important role in food security and other ecosystem services. The...

2 Assoc. Prof. of Forestry, University of California, Berkeley. Abstract: This study was conducted on various chaparral sites sampled throughout California in the range of the following species: chamise, Adenostoma fasiculatum; scruboak, Quercus dumosa; and Ceanothus cuneatus, & C. crassifolius. Data for elemental composition, total vegetation and leaf litter weights, and elemental storage weig...

The contribution of understorey vegetation (UVEG) to forest ecosystem biomass and carbon (C) across diverse forest types has, to date, eluded quantification at regional and national scales. Efforts to quantify UVEG C have been limited to field-intensive studies or broad-scale modelling approaches lacking field measurements. Although large-scale inventories of UVEG C are not common, speciesand c...

Several studies have shown a close relationship between vegetation fertility and different vegetation indices extracted from satellite data. The vegetation fertility in Arctic is at overall scales highly related to temperature. At lower scales surface material, snow cover, hydrology and anthropogenic effects (geese, reindeer) are determinant in constituting the different vegetation communities....

in many studies, topographic factors have been considered as an important factor in establishing the vegetation in different ecosystems. so, it affects vegetation composition and diversity by influencing soil moisture, fertility and soil depth. the aim of this research was to investigate the effects of slope, elevation and geographical aspects on species growth, forage production and vegetation...

The study was undertaken to find out how crop farmers in the Techiman municipality of Ghana determine and manage the fertility of their soils. Data were obtained through questionnaire and interview of one hundred and ten randomly selected farmers from the municipality between January and February, 2010. Frequency count, percentage and correlation coefficient were used to analyze the data. The f...
