Opis:
This paper presents the results of stratigraphic excavation and soil studies carried out at Mograt Island, the largest of the Nilotic islands in Sudan. Due to its restricted insular environments, Holocene alluvial deposits were observed to be interlocked with archaeological remains of different periods, allowing for a combined chronostratigraphic approach to study both cultural and climatic events. To better understand the environmental context through soil components and pedological features at a microscopic scale, soil block samples were accordingly collected and studied by the application of soil micromorphology. This approach provides insights into the history of Nile terrace aggradation through the suspension of Nile sediment loads under stillwater conditions as well as of the periodical establishment of shallow water pools at the islands’ plateaus by the surface run-off from local rains. Since these patterns vary significantly from the present situation, they offer a key to the scenario in which specific early agricultural and animal herding practices evolved.

Opis:
Five complex soil profiles in gully system on Nałeczów Plateau (E Poland) were examined. They represent the loess sediments modified by soil processes and postpedogenic transformations. Two examined profiles represent natural and mature Luvisols with diagnostic illuvial horizon (Bt argillic) developed on the edge of plateau geomorphologic level and in the relict valley bottom. The other soil profiles reflects postpedogenic soil degradation, redeposition and secondary accumulation (deluvia, colluvia and/or proluvia). Record of these processes are the micromorphological features created by lithological processes (=primary loess and secondary pedoliths) or by pedogenesis (mainly bioturbation, illuviation, de- and recalcification). The important group of microfeatures are pedorelicts which clearly confirm genetic dependences of pedoliths (deluvia and proluvia) and soils developed in situ and located in higher hypsometric levels in the catchment.

Opis:
The paper presents the results of micromorphological analyses concerning soil covers near Cherrapunji with mean annual rainfall of 12 000 mm. Two soil profiles representing typical land use: grass formation (Cherrapunji–1) and natural evergreen forest (Cherrrapunji–2) have been choosen. Processes leading to formation of Dystric Cambisols predominate in both profiles. However they have different weathering features. Soil cover under grass has more weathered quartz and contains less feldspars compared to soil cover in the forest area. Soils are characterized also by a large volume of pores which is typical for the tropical humid areas. The rapid infiltration of large amounts of water protects forest soil from surficial erosion. In case of soils under grass vegetation, micropores are filled with fresh organic matter (fine roots and plants tissue). Since both profiles are located on similar substratum (Paleogene sandstones) and under the same climatic conditions, it is assumed that the micromorphological differences are due to long-term (several centuries) differences in local land use.
