The poor mobility of organic pollutants in contaminated sites frequently results in slow remediation processes. Organics, especially hydrophobic compounds, are generally retained strongly in soil matrix as a result of sorption, sequestration, or even formation into non-aqueous-phase liquids and their mobility is thus greatly reduced. The objective of this study was to evaluate the feasibility o...

Autonomous navigation of robots in harsh and GPS denied subterranean (SubT) environments with lack natural or poor illumination is a challenging task that fosters the development algorithms for pose estimation mapping. Inspired by need real-life deployment autonomous such environments, this article presents an experimental comparative study 3D SLAM algorithms. The focuses on state-of-the-art Li...

American chestnut trees once dominated vast areas of deciduous forest in eastern North America, but the exotic chestnut blight almost eliminated the species from the region. Introduction of blight-resistant American chestnut hybrids will probably start in the next decade after many years of tree breeding. What were the historic effects of chestnut on forest soils, and what changes may follow re...

Manure applications can benefit crop productivity by adding required nutrients and organic matter to soil. There is a paucity of information on how soil microbial community dynamics will be altered by the application of manure to different landscape positions. Thus, an in situ field study was conducted during the summer and winter months to evaluate microbiological properties of three soil type...

The use of cost-effective methods for measurement WHC is common in underdeveloped and developing countries, but the accuracy these compared to sophisticated more expensive alternatives unclear. To compare different methods, 30 random samples clay loam sandy soils Jhansi, India were used. here were: FAO in-situ method (FAO), Keen-Raczkowski box (KM), funnel (FM), column (CM) pressure plate (PPA)...

verticillium wilt verticillium dahliae is now a days commonplace in olive orchards in north of iran. root-knot nematode, meloidogyne javanica, as well is one of the most widely disseminated plant parasitic nematodes in olive orchards of iran. this study was arranged to find the effects of two sets of pot beds on these pathogens' interaction. microsclerotia of verticillium dahliae and j2s o...

[1] We conducted a modeling study to evaluate how soil hydrological properties regulate water and carbon dynamics of grassland ecosystems in response to multifactor global change. We first calibrated a process-based terrestrial ecosystem (TECO) model against data from two experiments with warming and clipping or doubled precipitation in Great Plains. The calibrated model was used to simulate re...

Soil organic carbon (SOC) turnover plays a pivotal role in achieving C neutrality, promoting retention and increasing soil fertility. Residue biochemistry texture essentially determine SOC distribution (including CO2 mineralization stock soil) farmland. However, less is known about allocation of residue-C with contrasting the fate under two different textures. This study was conducted 61-day ae...
