Abstract :

A study to analyze the influence of tillage equipments on the physical properties of andosols was conducted.Four ploughing methods were tested on andosols in the Malagasy Highlands. There are manual ploughing with angady, animal powered, cultivator, and tractor drawn implement. Zero-tillage was used as a control. The parameters measured are the proportions of the soil materials, the structural stability, the density, the porosity, the infiltration and the resistance of the soil. It has been shown that the proportions of materials have varied relatively after ploughing.
