WebClay minerals form as the products of low-temperature chemical weathering reactions near the earth's surface. Clay minerals contain hydrogen and oxygen in the form of hydroxyl (for example the composition of kaolinite : A l 2 S i 2 O 5 [ O H] 4 ). Web1 de jun. de 2002 · The clay mineralogy of soil samples from the Morrow Plot Experiment (University of Illinois, Urbana Campus) was investigated. Analysis of soil samples taken at various intervals between 1913 and 1996 indicates that there is a significant influence of cropping method on the clay minerals in the soils. Curve decomposition methods were …
Web2. CLAY MINERALS IN SOILS The clay mineralogy of a soil is the result of several factors interacting with the soil parent material: climate and consequent intensity of weathering; accumulation and losses of substance within the soil profile, often related to its position in the landscape; vegetation; and the dura-tion of these influences.
