Results of the study on morphological, physical, and chemical characteristics of three pedons developed on volcanic materials of Mt.

Pedon BM1 is classified as undeveloped, 8M2 is medium developed, and 8M3 is strongly developed. This is mainly caused by differences in the relative age of the parent rocks and elevation. Although classified as undeveloped, the soil represented by pedon BM1, the youngest, has immediately been used by farmers for rice cultivation because of water abundance,

Abstract:

Seven typical pedons in semi-arid region of Vedurukuppammandal in Chittoor district of Andhra Pradesh were studied for their morphological, physico-chemical and chemical characteristics to evaluate the suitability of soils for growing rice, groundnut and sugarcane. The soil belongs to Entisols, Inceptisols and Alfisols. Pedons (P1, P2 and P4) were marginally suitable (S3) for rice and moderately suitable (S2) for groundnut and sugarcane, whereas pedons (P3, P6 and P7) were not suitable for rice and moderately suitable (S2) for groundnut and sugarcane and pedon (P5) was moderately suitable (S2)

Soil surveys are generally treated as static documents. Many soil survey users assume that pedon data generated 30 to 50 yr ago still represents today's soil, as short-term changes in soil properties are perceived to be limited to the soil surface and thus pedologically insignificant. In this study, we re-sampled and re-analyzed 82 pedons with historical descriptions and laboratory data in Iowa, United States, to evaluate changes in
