A computer simulation model for investigating the effect of land application of sludge on runoff water quality
… nutrient transport processes which occur in the soil following organic waste applications. CREAMS-NT accounts for nutrient addition through fertilization and rainfall and losses of N by volatilization, denitrification, plant uptake, leaching, and overland flow. Data required by CREAMS-NT includes …

The effect of soil parameters on the bioavailability and retention of lead in rats
This study investigated the relationship between soil cation exchange capacity (CEC) and soil amendments (lime and phosphate) to the retention of lead in soil fed to rats. This study also related the amount of lead that can be extracted from in situ contaminated soils from a secondary smelter site …

An assessment of morphological, physical, chemical, and mineralogical properties of soils derived from volcanic deposits in Rwanda
… The objectives of this study were to assess soil properties at different elevations and among soils developed from volcanic materials differing in petrological composition and age, and to compare soils under the native vegetation to those under cultivation. The soils are characterized by …

Characterization and agronomic evaluation of biochar amendments in a midwestern loam soil: effects on soybean yield, soil nutrient retention, and leachate quality
The development and application of biochar as a soil amendment has shown promising results for improving soil fertility, enhancing nutrient retention, and mitigating environmental degradation in agroecosystems. This dissertation investigates the physicochemical properties of biochar derived from …

Characterization of soils via portable X-ray fluorescence spectrometer
Characterization of soil is critically important for any soil scientist initiating their research. Soil pH and soil cation exchange capacity (CEC) are two of the important soil properties that cannot be disregarded when considering the quality of soil. Current methods for evaluating these …
