Assessment of Soil Structural Stability Under Different Land Uses Using Some Predictive Indices in Abakaliki, Southeastern Nigeria



Soil is fundamental and basic resource for agricultural practice. Consequently, soil structural stability is a potential indicator for wide variety of choices to which it is used for ranging from agricultural to engineering considerations. This is because the structural stability of soil influences its nutrient retention and supply, water storage and transmission, aeration propensity, strength and trafficability and capacity to support foundations (Obi, 2000).  According to Ogbodo (2012), the soil serves as the natural media that provides the physical and chemical environment for crop production. The primary purpose of soil is to hold and provide water and nutrients to plants, permit gas exchanges to and from their roots, as well as mechanical support. As corroborated by Ekpe (2002), soil structural stability strongly correlates with fertility, infiltration rate, flow of air or water and degree of ramification of network of roots. Furthermore, in assessing of soil structural stability the two major factors of interests are size, stability of aggregates, shaping or orientation of the aggregates (Ekpe, 2002).
