Résumé
Soil structure is an imponant soil physical aspect which influences not only mny other soil propenjes but also the crop growih and yied. Many surface management techniques can be adopted which affect soil structure through formation as well as stabilization of aggregates. The changes brought about in the soil shuctural features are reflected in soil physical properties such as porosity. bulk density, aggregate slabity, sorptivity, hydraulic conductivity, steady-state flow rate, man pore size etc. Soil shucture is not a static property and changes with water content and other agencies of stress. The formation of aggregates and pores and their stabilization is very ilnportant to maintain a good soil structure and to increase productivity of the soils. Stable aggregation and proper pore size distribution determine a good soil tilth...
