Changes in Soil Properties Under No-Tillage,le to show concern about how this change in soil management may affect soil properties. For any crop production system to be widely accepted and used it must maintain the physical properties of the soil, and allow for replacement of nutrient removal and other losses. It must also maintain a soil env

No-Tillage in the Tropics,omprises about one-third of the land surface of the earth. It is difficult to clearly define the tropics, and for convenience is often given a latitudinal definition, which includes the zone between Tropic of Capricorn and Tropic of Cancer or latitudes of 23.5° N and S (Kalpagé, 1974). Another defin
