Modern concepts of soil conservation

Approaches to soil conservation are in constant evolution and improvement. This paper summarizes some of the modern approaches, ranging from no till to conservation agriculture to sustainable land management. These approaches are not separate, but components of a continuum of conservation approaches applicable at different levels and different scales. No tillage is important at the detailed, farm level, while CA and SLM are important at the farming systems and corporate levels. The successes achieved with no till in Argentina (also Brazil, Paraguay, Uruguay, Mexico, Canada, Australia, and others) illustrate how these concepts relate to each other.
