In view of the grave consequences of soil degradation on ecosystem functions, food security, biodiversity and human health, this book covers the extent, causes, processes and impacts of global soil degradation, and processes for improvement of degraded soils.

Soil conservation measures, including soil amendments, decompaction, mulching, cover cropping, crop rotation, green manuring, contour farming, strip cropping, alley cropping, surface roughening, windbreaks, terracing, sloping agricultural land technology SALT , dune stabilization, etc. Particular emphasis is given to soil pollution and the methods of physical, chemical and biological remediation of polluted soils.

This book will lead the reader from the basics to a comprehensive understanding of soil degradation, conservation and remediation. Abhilash, Journal of Cleaner Production, April, Help Centre.

Industry Reviews "The book Continuous no-till cropping systems with cover crops Figure 8 have been found to be particularly effective because of their ability to quickly enhance levels of organic matter near the surface. Langdale et al. Elevated organic matter levels in the top several centimeters of an eroded soil can dramatically increase water infiltration, nutrient cycling and resistance to detachment Franzluebbers The system starts with selective harvesting and pruning of natural vegetation.

Trunks and large branches are used for firewood and timber, while smaller vegetation is spread as mulch. During the first year, farmers broadcast pioneer crops like sorghum and beans, which grow up through the mulch. In subsequent years, maize is the primary crop. The trees and shrubs dispersed throughout fields are aggressively pruned several times a year to produce mulch and prevent excessive shading of crops. The decomposing mulch supplies crops with nutrients, although additional fertilizer is often used New Agriculturalist These layers dissipate the kinetic energy of raindrop impact, improve infiltration and increase water retention Figure The result is improved water availability for crops.

Farmers view the Quesungual System as a method of enhancing crop productivity that also happens to minimize soil erosion Hellin Used with with permission from Steve Fonte. Dallas Timmerman, a grain and livestock farmer in Treherne, Canada, collaborated with Lobb and graduate student Diane Smith to quantify the benefits of landscape restoration.


In the fall of , a two-year project was initiated on four eroded hilltops on the Timmerman farm. Ten centimeters of topsoil were added to half of each hilltop, while the other half was left unamended. In , field pea yields were 64 percent higher on the restored plots. At other project sites near the Timmerman farm, wheat yields and flax yields were percent and 94 percent higher, respectively, on restored hill tops Flookes While the movement of large amounts of soil is inherently energy intensive, precision agriculture technologies offer the potential to optimize the efficiency of topsoil redistribution.

He started by using yield monitor and topographic data to identify areas that performed poorly due to historical topsoil loss. Identifying depositional areas with excess topsoil was the bigger challenge. The next stage of the project engaged graduate students in Agricultural Engineering at Cornell University in an optimization problem.

Working from maps of relative yield and topsoil depth, a team of four students developed software for planning the optimal redistribution of topsoil across an agricultural landscape, taking into account the workload involved in moving topsoil from one place to another Ju Used with permission from Clay Mitchell. Intensive research has evaluated the effects of accelerated water erosion on crop productivity. Loss of nutrients to erosion, while historically significant, is largely reversible using nitrogen and phosphorus fertilizers.

Soil Erosion – Causes and Effects

Loss of hydrologic function is a much more serious challenge but gradual restoration is possible through practices that raise organic matter levels, especially at the soil surface. Farming system strategies that minimize tillage, maximize living cover e. Mechanical redistribution of topsoil from catchment areas to denuded areas, also known as landscape restoration, appears to have promise in some agricultural landscapes, especially when precision agriculture technologies can be used to optimize the efficiency of topsoil transfer.
