Field Experiments in a Fractured Clay Till 2. Solute and Colloid Transport
A field tracer experiment was conducted in a lateral flow field in the weathered and highly fractured upper 6 m of a 40-m-thick clay-rich till plain in southwestern Ontario. In the upper 3 m where fractures are closely spaced (<0.13 m) the advancing front (C/Co = 0.01) of the nonreactive solute tracers, bromide and O, migrated at rates of 0.01 to 0.07 m/d, over distances of 4 and 6 m and under ...
متن کاملConversion to No-Till Improves Maize Nitrogen Use Efficiency in a Continuous Cover Cropping System
A two-year experiment was conducted in the field to measure the combined impact of tilling and N fertilization on various agronomic traits related to nitrogen (N) use efficiency and to grain yield in maize cultivated in the presence of a cover crop. Four years after conversion to no-till, a significant increase in N use efficiency N harvest index, N remobilization and N remobilization efficienc...

متن کاملCheck the Soil Yield Stress in Situations with different Slope on a Hill Slope with Pasture Cover with the Occurrence Sulification Erosion
One of the most important types of water erosion, is massive erosion. Soils with fine particles (especially silt particles) have little stability against erosion, because they have more water holding capacity and thus increase the saturation moisture and the likelihood of this type of erosion. So In this study, to investigate the relationship between particle size of silt, with behavior and rhe...
متن کاملEvaluation of Reactive Clay in Indian Shale
Shale formations are composed of clays, feldspars, carbonates, and quartz as major ingredients. Among all the constituents, clays are the most important parameter from an application point of view because of their possibly sensitive nature; they are further categorised as migrating (illite, kaolinite, and chlorite) and reactive (smectite and mixed layers) clays. Smectite is always considered as...
