Gypsiferous Aridisols are of great importance and extent in arid and semi-arid environments. There is a close relationship between soil genesis and landscape positions. This study aimed to determine the genesis and classification of gypsiferous soils and to investigate the relationship between micro-and macro-morphology of gypsum crystals and geomorphic positions in Rafsanjan area. The study ar...

Soil acidification in tea plantations has become a key factor restricting the development of industry. Biochar reduces soil acidity significantly and good short-term effects acidic improvement plantation trials, but duration effect long-term environmental biochar are still unclear. In this study, to which was applied five years ago studied. The separated analyzed for surface elements, aluminum ...

Soil compaction easily causes root hypoxia stress, resulting in poor growth and the absorption of soil water nutrients. We hypothesized that aerated irrigation (AI) could enhance nutrient uptake utilization, thus unlocking high yield potential by increasing aeration morphology indicators compared with non-aeration treatment. A greenhouse experiment was conducted to investigate effect on cucumbe...

Soybean [Glycine max (L.) Merr.] yield in claypan soils varies systematically with soil properties and landscape position. This is likely caused by soil interactions with soybean roots. Field observations of soybean root distribution are needed to reveal its effect on yield variability. This study examined profi le distributions of soybean root length density (RLD) and average root diameter (AR...

Undoubtedly, land degradation linked to desertification causes a decrease in qualitative and quantitative features of natural resources. This research aimed to assess land desertification by local residents and their role in controlling desertification in Isfahan province, Iran in 2016. The criteria were soil climate, vegetation, erosion, and demography. The indicators of soil texture, stone fr...

Having specific properties, clay minerals including palygorskite have considerable influence on soil physico-chemical characteristics as well as the stage of soil development. The objectives of current study were to determine the distribution, origin and formation conditions of palygorskite in the Tertiary sediments and associated soils in Darab, Fars Province. Based on the field observations a...

In the Mediterranean region there is growing concern for the potential increase in erosion risk associated with climate change and increasing storm frequency. The central Ebro basin is the region facing the greatest problems of desertification in northern Spain and there is a need to assemble information on short-term erosion rates associated with individual storm events. The Be technique offer...
