Bacterial biocontrol strains used as an alternative to chemical fungicides may influence bacterial communities in the rhizosphere and effects might differ depending on the soil type. Here we present baseline data on the effects of Pseudomonas jessenii RU47 on the bacterial community composition in the rhizosphere of lettuce grown in diluvial sand, alluvial loam and loess loam at the same field ...

introduction: soil genesis and development in arid and semi-arid areas are strongly affected by geological formations and geomorphic surfaces. various morphological, physical, and geochemical soil properties at different geomorphic positions are usually attributed to different soil forming factors including parent material and climate. due to variations in climate, geological formations (quater...

To meet the increasing demand for wood and wood products, the Southern Hardwoods Laboratory is investigating silvicultural techniques such as fertilization. Sweetgum, water oak, and willow oak have responded to N and NPK on clay soils of the Mississippi River floodplain. Yellow-poplar growth has been improved by NPK fertilizers on eroded sites in the Silty Uplands, and in the greenhouse sycamor...

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, ...

Thirty-four permitted earthen waste storage structures (EWSS) were investigated to characterize their hydrogeologic setting using digital soils data, digital elevation data, geologic maps, and oblique aerial photographs. Nearly 18 percent of the sites were constructed above alluvial aquifers and on flood plains. More than half of the area within 3.2 km of most sites had soils with a vertical pe...

This article presents the problems of studying and improving physical properties water, total porosity volume weight alluvial soils ancient irrigated meadows Bukhara oasis. Keywords: general porosity, water properties, oasis weight.

Bradyrhizobium japonicum strains that have the nosZ gene, which encodes N2O reductase, are able to mitigate N2O emissions from soils (15). To examine the distribution of nosZ genotypes among Japanese indigenous soybean bradyrhizobia, we isolated bradyrhizobia from the root nodules of soybean plants inoculated with 32 different soils and analyzed their nosZ and nodC genotypes. The 1556 resultant...

The aim of the study. research was obtaining new information about genesis, current status, diagnostic features and properties alluvial-meadow-forest soils southern slope Great Caucasus within Azerbaijan to perform taxonomic attribution those in accordance with International Classification Soils compliance Reference Base for soil resources (IUSS Working Group WRB, 2014). Location time Alluvial-...

Radiocarbon dating of late Quaternary deposits and shorelines of Lake Mojave and cation-ratio numerical age dating of stone pavements (Dorn. 1984) on the adjacent Soda Mountains piedmont provide age constraints for alluvial and eolian deposits. These deposits are associated with climatically controlled stands of Lake Mojave during the past 15.000 yr. Six alluvial fan units and three eolian stra...
