Chapters’ topics are various, ranging from irrigation practices to soil nutrient, land use changes or tillage methodologies. The book is subdivided into fourteen chapters, sorted in four sections, grouping different facets of the topic: introductive case studies, erosion URBANA, Ill. – Soil erosion is a major challenge in agricultural production. It affects soil quality and carries nutrient sediments that pollute waterways. While soil erosion is a naturally occurring process, agricultural activities such as conventional tilling exacerbate it. Farmers implementing no-till practices can significantly reduce soil erosion rates, a new University of Illinois Soil Erosion in the United States.

With average soil production and geological erosion rates of <0.2 mm/yr and average soil erosion rates under conventional agricultural practices of >1 mm/yr, the time required to erode through the soil is on the order of a few hundred to a few thousand years for an initially decimeter- to meter-thick soil profile typical of undisturbed areas of temperate and tropical latitudes .

Therefore depending on the agents of erosion, soil erosion is classified mainly as water erosion The agricultural plants that often replace the trees cannot hold onto the soil and many of these plants, such as coffee, cotton, palm oil, soybean and wheat, can actually worsen soil erosion. And as land loses its fertile soil, agricultural producers move on, clear more forest and continue the cycle of soil loss.
