Publisher's Synopsis
Soil stabilization is a group of earthwork technologies to improve soil characteristics during the construction process and to improve mechanical and load bearing properties. The text Mechanisms of Soil Stabilization summarizes current knowledge on soil organic matter (SOM) dynamics and stabilization and to synthesize a conceptual SOM model based on physicochemically defined SOM pools. In first chapter, a laboratory experiment has been conducted to evaluate the effects of waterborne polymer on unconfined compression strength and to study the effect of cement grout on pre-venting of liquefiable sandy soils. Second chapter conducts a short-term incubation experiment to assess the effects of biochar application on the decomposition of added bagasse compost in three rural soils with different pH values and textures. The behavior of clayey soil stabilized with rice husk ash and lime has been discussed in third chapter. Fourth chapter deals with a chemical stabilization of an expansive high plastic soil of Pliocene deposits exposed at El-Kawther quarter using cement kiln dust (CKD) and cement kiln dust with lime (L) to reduce their swelling and improve their geotechnical properties. Fifth chapter focuses on mechanisms and distribution of different forms of phosphorus, its transformation and dynamics in the soil. Sixth chapter discusses on changes in soil nutrition, physical properties and microbes, tree nutrition and growth, and water nutrient contents in loblolly pine plantations and silvopastures in response to fertilization with conventional fertilizer and poultry litter. Seventh chapter reviews the progress made in defining the physiological and biochemical mechanisms of adaptation of brachiariagrasses to low fertility acid soils. Eighth chapter deals with soil indicators of hillslope hydrology. The database used in ninth chapter reveals an adequate representativeness of the soil classes distributed over the Brazilian territory. An application approach to Kalman filter and computerized tomography (CT) scanners for soil science has been presented in last chapter.
