The objective of this work is to provide further explanation regarding the pedogenesis of Red Mediterranean soils in the karstic Mediterranean regions of Turkey. Sedimentary petrology and mineralogy of limestones are the factors that control
the course of the pedogenesis. Most of the red soils in the studied karstic regions were likely developed during the Tertiary and hot and humid periods of the Quaternary epochs. Large body of soils which are found in deep limestones suggest their formation

Based on journal publications and a meta-analysis approach, this paper investigates the effects, and their spatiotemporal variations, of different land covers on red soil rehabilitation in China. Results indicate that all the land covers used in red
soil rehabilitation had been effective in improving degraded red soils but the degrees of effectiveness varied. Soil organic carbon was the most sensitive of the 3 major soil nutrients considered with regard to land-cover change during ecological
rehabilitation. Coniferous and broadleaf mixed forest was detected as the most effective land cover in red soil rehabilitation. Some spatiotemporal trends of land-cover effectiveness on red soil rehabilitation exist in a statistically significant sense

Interrill erosion from disturbed and undisturbed samples in relation to topsoil aggregate stability in red soils from subtropical China
for the interrill erodibility parameter, from both disturbed and undisturbed samples for red soils in subtropical China. Six cultivated areas of sloping land with red soils were selected, and topsoil aggregate stability was analyzed using the Le Bissonnais method
extend the validity of soil aggregation characterization as an appropriate indicator of soil susceptibility to interrill erosion in red soils from subtropical China.
On the aeolianite-red sands relationship in coastal Natal in Palaeoecology of Africa and the surrounding islands. Volume 15. Southern African Society for Quaternary research. Proceedings.
Observations on the aeolianite-red sand relationships in Natal and Israel are reported and compared. It is suggested that only originally highly calcareous sands (over about 25 % CaCO) were cemented into aeolianite in Natal. At a lower content

The aims of this study were to evaluate the restorative effects of re-vegetation and vegetation type on soil enzyme activities and microbial functional diversity of eroded red soil. Soil samples were collected by horizon from eroded soils that had
been restored for 18 years. Un-eroded soils planted with these vegetation types and an eroded bare soil served as references. The sampling site was located at the Red Soil Ecological Experiment Station in Jiangxi Province. Soil microbial functional
