During forest succession, litterfall nutrient fluxes increase significantly. The higher inputs of organic matter and nutrients through litterfall affects positively soil fertility and the species composition, which are essential components in forest restoration and management programs. In the present study, the input of nutrients to the forest soil via litterfall components was estimated for tw...
Alluvial slopes are piedmonts characterized by parallel steam channels rather than alluvial fans. They are common landforms in extensional basins of the south-western United States but have received little attention from geomorphologists or sedimentologists. Persistence of channellized flow across piedmonts, as opposed to sheetflooding due to loss of flow confinement on alluvialfan surfaces, di...
In the article, mechanical composition and type level of salinity meadow-alluvial soils Gijduvan district Bukhara region were determined. According to obtained data, this soil is mostly non-saline, found in layer below 1 meter. The moderate driving layer, but heavy lower layers. different soil-climatic conditions our republic, including determining general properties irrigated Gijduvon region, ...

In this study, we examined the influence of different nitrogen (N) application rates (0, 168, 240, 270 and 312 kg N ha(-1)) on soil properties, maize (Zea mays L.) yields and microbial communities of three types of soils (clay, alluvial and sandy soils). Phospholipid fatty acid analysis was used to characterize soil microbial communities. Results indicated that N fertilization significantly dec...

Although people have always classified soils, it is only since themid 19th century that soil classification emerged as an important topic within soil science. It forced soil scientists to think systematically about soils and its genesis and developed to facilitate communication between soil scientists. It has also been the cause for much debate and confusion but two internationally accepted sys...
