Abstract

The Importance of the Problem "Stability of Soil Aggregates" The assessment of soil quality indicators and their interpretation should be considered as a process in which all soil resources are assessed in terms of soil functions and the changes that would occur in these functions as a result of Natural or specific stresses and / or certain human activity. The process of formation of soil aggregates or organominerals complexes from primary particles and humic and other bounding substances, is called aggregation. It is the first step in the development of soil structure. Humified organic matter, with its long polymer chains and electric charge balanced by polyvalent cations, is a very effective cementing agents. Structural stability is the ability of a soil to retain its arrangements of solids and void space when external forces area applied. External forces can be natural or anthropogenic. The aggregate stability depends on the bonding agents involved in cementing the particles together
