| Summary: | Active and inactive features can occur in the same horizons. Aquic Paleudalf. Both soils have shallow fine sandy loam at or above field capacity. Iron reduction could not be cautiously. The incidence of high rainfalls over the study characteristics of saturation in the Wockley soil, while the checked when the Wockley soil was saturated. The E horizon chroma soil colors, mottling, and iron and manganese clayey soils. Field evidence of saturation consisted of low- dipyridyl dye could not be fully tested; however it did not dipyridyl dye for field identification of iron-reduction. The give false positive readings. horizons of the Wockley soil, and plinthite occurs. The Katy horizons. Micromorphology shows iron being actively reduced in both soils. Highly crystalline free iron was more in the upper profiles of both soils, through destruction of matrix, or clay coatings or plugs covering the nodules. nodules are not being reduced, having sharp boundaries to the nodules, the presence of cuffent pore and void linings; and of the Katy soil seems prone to reduction of iron when water period exceeded the expected probabilities, implying that Pore and void linings were the most indicative field prevalent in high-chroma segments of the soils. The cl,a'- rare high rainfall events or sequences of events promote reduction potential (Eh), and iron phases; and to test a,a'- sand-silt coats on ped faces were convincing evidence of saturation and reduction in the Katy soil. Micromorphology saturation and reduction, but continuing high rainfalls seasonal saturation to soil morphology, micromorphology, soil segregations. Ironstone nodules are plentiful in upper Bt showed that field evidence in these soils must be interpreted soil has distinct sand-silt coats on ped faces of Btg some fine soft agglomerations in the Katy soil. Some iron suggest that climatic probabilities need to be more surface soils, and clay loam subsoils, overlying buried tables are present. Poorly crystalline free iron was very low thoroughly documented. Manganese was reduced when soils were Two sites were established in Harris County, Texas, to relate Wockley soil is a Plinthic Paleudalf and the Katy soil is an |
