Bacteria able to produce biosurfactants can use petroleum-based hydrocarbons as a carbon source. Herein, four biosurfactant-producing Pseudomonas aeruginosa strains, isolated from oil-contaminated saline soil, were combined to form a bacterial consortium. The inoculation of the consortium to contaminated soil alleviated the adverse effects of salinity on biodegradation and increased the rate of...

Reliable and real-time information on soil and crop properties is important for the development of management practices in accordance with the requirements of a specific soil and crop within individual field units. This is particularly the case in salt-affected agricultural landscape where managing the spatial variability of soil salinity is essential to minimize salinization and maximize crop ...

Germination and early growth of maize Sweet Maize (Zea mays L.), var. (SEL. CONETA) under irrigation with saline water were investigated in a pot experiment with different soil types. Seven salinity levels of irrigation water up to 12 dS/m were used on a Clay soil (C) and a Sandy-Loam (SL). Emergence of maize was delayed under irrigation with saline water, and the final percentage of germinatio...

1988 PREFACE The intent of this publication is twofold: (1) to serve as a user guide for soil scientists and others interested in learning about the value and use of digital elevation model (DEM) data in making soil surveys and (2) to provide documentation of the Soil Landscape Analysis Project (SLAP). This publication provides a step-by-step guide on how digital slope-class maps are adjusted t...

Updating categorical soil maps is necessary for providing current, higher-quality soil data to agricultural and environmental management but may not require a costly thorough field survey because latest legacy maps may only need limited corrections. This study suggests a Markov chain random field (MCRF) sequential cosimulation (Co-MCSS) method for updating categorical soil maps using limited su...

abstract the quality of soil maps depends upon their ability to show the soils variability. thus, the accuracy of the maps used for crop recommendations is due to the accuracy of soil maps. this study was performed to investigate the amount of soil properties and crop yield spatial variability in s 2 and s3 units of a semi-detailed quantitative suitability map (1:50000 scale) for irrigated whea...

due to the lack of fresh water resources, the use of saline water for the production of plants such as wheat and kochia is inevitable. to sustain production, the effect of saline water on the plants and soil in each region must be studied. therefore in this paper, the effects of irrigation with saline water to produce plants such as wheat and kochia, as well as changes in the soil salinity prof...

This research was carried out to determine the fertility and microelement scopes of agricultural soils İzmir province create a database distribution maps (pin maps) by using geographic information systems technique between 2014-2017. Within scope research, total 502 soil samples, representing areas, were taken from 0-20 cm depth with 2.5 km x grid intervals. In samples taken; texture, pH, EC, l...

Saline lakes can increase the soil and water salinity of the coastal areas. The main aim of this study is to distinguish the characteristics of the spectral reflectance of saline soil, analyze the statistical relationship between soil EC and characteristics of the spectral reflectance of saline soil, and to map soil salinity east of the Maharloo Lake. The correlation between field measurements ...
