Skidding operations induce changes in soil physical properties, which have the potential to impact soil sustainability and forest productivity. Our objective was to investigate the effects of traffic frequency, trail slope, and soil moisture content on soil compaction, total porosity and rut depth. Treatments included a combination of three different traffic intensities (3, 7, and 14 passes), t...

Soil moisture is a key limiting resource in arid and semi-arid environments for woody shrub species. We assessed if three arid communities differed in their level of dry season soil moisture content and if the dominant species in these communities differed in their ability to use soil moisture. Water potential of all of the dominant woody plant species occurring in chaparral, coastal sage, and ...

The contamination of soil with petroleum products is a major environmental problem. Petroleum products are common soil contaminants as a result of human activities, and they are causing substantial changes in the biological (particularly microbiological) processes, chemical composition, structure and physical properties of soil. The main objective of this study was to assess the impact of soil ...

the accuracy and effectiveness of precision agriculture is highly depending on accuracy and time analysis of the soil moisture conditions. monitoring of the soil water status is a proper method for optimizing the agricultural irrigation. automation irrigation, based on soil moisture measurement by smart sensors has the potential to provide maximum water use efficiency by maintaining soil moistu...

Soil moisture simulation in current landsurface schemes is diverse: in terms of the realism (and complexity) of the parameterizations and in terms of the resulting predictions. Even after careful adjustment, the range in soil moisture among the results from the 14 schemes compared for the HAPEX-MOBILHY (S. France) site's 1.6 m soil layer remains around 100 mm (the annual precipitation for HAPEX...

In regions affected by seasonal and permanently frozen conditions soil moisture influences the thermal regime of the ground as well as its ice content, which is one of the main factors controlling the sensitivity of mountain permafrost to climate changes. In this study, several well established soil moisture monitoring techniques were combined with data from geophysical measurements to assess t...

A number of automated techniques for point measurement of soil moisture content have been developed to an operational level over the past few decades. While each of those techniques have been individually evaluated by the thermogravimetric (oven drying and weighing) method, typically under laboratory conditions, there have been few studies which have made a direct comparison between the various...

of the spatial variability in soil moisture within the root zone. An instrument for making rapid measurements of the soil moisture Studies have shown that soil moisture content can content in the root zone is an essential tool for many applications, be inferred from measurements of the soil electrical including understanding of soil water dynamics, evaluation of agriculresistance (e.g., Seyfrie...

Fluctuations in soil moisture create drying-rewetting events affecting the activity of microorganisms. Microbial responses to drying-rewetting are mostly studied in soils that are air-dried before rewetting. Upon rewetting, two patterns of bacterial growth have been observed. In the Type 1 pattern, bacterial growth rates increase immediately in a linear fashion. In the Type 2 pattern, bacterial...
