15. Supplementary Notes Research performed in cooperation with the Texas Department of Transportation and the Federal Highway Administration. Project Title: Develop Guidelines and Procedures for Stabilization of Sulfate Soils 16. Abstract Sulfate-bearing subgrade soils treated with calcium-based stabilizers often experience heaving problems (three-dimensional swell) due to chemical reactions w...

Seedlings of five native tussock species grown in the glasshouse on mountain subsoil showed outstanding responses to nitrogen and phosphorus fertiliser in combination. The most vigorous species was silver mssock but this produced less dry matter than an introduced grass, Yorkshire fog, grown on the same soil. Tussocks in general responded positively to applications of magnesium and potassium bu...

Boron adsorption onto lime soil from Balıkesir University campus was studied to evaluate the effects of irrigation water cations (Ca2+, Mg2+, K+ and Na+) clays (kaolinite, montmorillonite, clinoptilolite clays). The concentrations for boron were in range 0-1,450 mg/L 0-700 mg/L, respectively. experimental maximum capacity cation effect 0.764 mg/g this value seen obtain at high middle concentrat...

One of the main factors of water erosion is the natural characteristics of the soil called "erodibility" or"detachability". The present study aims to analyze the variations of soil erodibility factor in different plains and thefactors related to it. Erodibility is one the key factors in some models of erosion and sediment such as Universal SoilLoss Equation (USLE), Revised USLE (RUSLE), and Mod...

Industrial waste generated is a major contributor of total worldwide. The proper mechanism for management these needs to be established, especially in developing countries. Therefore, this paper attempts evaluate the influence compactive effort on strength characteristics lime treated laterite soil mixed with untreated textile effluent. study was carried out index properties, unconfined compres...

Natural hydraulic lime soil has good mechanical properties; as an earthen ruin restoration material, its durability is insufficient. Despite natural being a topic that been studied for several years from different researchers, it not yet fully considered the improvement of durability. This work aims to experimentally investigate enhancement properties lime-based. The performance limestone by ad...

homogeneity and uniformity of soil particles is a most potent factor which affects soil spectral signatures. geometric standard deviation of soil particles (?g) exhibits the homogeneity of soil components. this study presents the influence of ?g on spectral studying of soil geometric mean particle diameter as well as lime. the study was conducted in pol-e-dokhtar using the data set of lissiii-p...
