Soil Erosion- Causes and Effects - Share and discover research.

Subsurface erosion by soil piping is not represented in currently used soil erosion models. Therefore more research is needed to better understand the morphology and connectivity of soil pipes, their subsurface catchments, as well as soil erosion rates by piping in different environments. Knowledge of thresholds that induce erosion in pipes and.

COMPARISON OF THREE SOIL EROSION CONTROL TREATMENTS A Research Paper Presented for the Master of Science in Agriculture and Natural Resources Degree The University of Tennessee at Martin Eatedal Alqusaireen December 2012. ii Acknowledgments I would like to thank all the people that helped me finish this project. I am grateful to my advisor, Dr. Sandy Mehlhorn, for her help and support during.

Soil erosion is a process of detachment and transportation of soil by natural agencies of water and wind. Factors Influencing Soil Erosion: There are many factors which influence the process of soil erosion; these are discussed below: 1. Rainfall: Precipitation is the most forceful factor causing erosion.

For example, a Desert Afforestation and Soil Conservation Research Centre was established at Jodhpur in 1952 under the Forest Research Institute, which was later converted into Central Arid Zone Research Institute in 1959 with responsibility for the Rajasthan desert and arid zone research.

The paper compares modelled natural soil erosion rates with actual soil erosion rates. Across about 40% of borders, the authors say, political borders do match with environmental borders in that there is a significant discontinuity in the natural rate of soil erosion.

The loss of trees, which anchor the soil with their roots, causes widespread erosion throughout the tropics. Only a minority of areas have good soils, which after clearing are quickly washed away by the heavy rains. Thus crop yields decline and the people must spend income to import foreign fertilizers or clear additional forest.

International Journal of Sediment Research, the Official Journal of The International Research and Training Center on Erosion and Sedimentation and The World Association for Sedimentation and Erosion Research, publishes scientific and technical papers on all aspects of erosion and sedimentation interpreted in its widest sense.

Soil Research is an international journal of soil science publishing high quality research on: soil genesis, soil morphology and classification; soil physics and hydrology; soil chemistry and mineralogy; soil fertility and plant nutrition; soil biology and biochemistry; soil and water management and conservation; soil pollution and waste disposal.

Our state of the environment report for soil highlights the importance of soil. It looks at the latest available evidence and the need for further monitoring and research.

Soil erosion is contingent on multiple factors, including climate, soil, topography, and land use (Wei et al., 2012); thus, soil erosion is typically episodic and highly localized (Trimble and Crosson, 2000). Moreover, eroded sediment may exit the watershed quickly or be stored for very long periods of time (Bracken et al., 2013). In recent.

Construction of the National Soil Erosion Research Laboratory (NSERL) was funded by Congress in 1977, and the building was completed in 1981. Today, the ARS NSERL scientists continue research studies into the processes of soil erosion by water and development of improved erosion prediction technologies.
