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...

A pot experiment was carried out in the net house of Bangladesh Institute of Nuclear Agriculture (BINA) to study nutrient content and their uptake by different rice varieties (NERICA-1, NERICA-10 and BRRI dhan48) in response to different levels of arsenic (As) under varying moisture regimes. Three levels of As were added viz. 0, 30, 60 ppm to the pot soil from sodium arsenate (Na2HAsO4. 7H2O). ...

increased soil dryness of hillsides and lands around the gully causes the aggravation of the gully erosion which leads to the desertion of the environment. soil moisture contents are various in different soil depths, gully positions, and in various land uses. these are fundamental for ecosystem sustainability in arid and semi-arid area. therefore, understanding the behavior of soil moisture in ...

15. Supplementary Notes Project performed in cooperation with the Texas Department of Transportation and the Federal Highway Administration. Project Title: Rapid Field Detection of Sulfate and Organic Content in Soils URL:http://tti.tamu.edu/documents/0-6362-1.pdf 16. Abstract In recent years, the Texas Department of Transportation (TxDOT) has experienced problems chemically stabilizing modera...

The temperature sensitivity (Q10) of soil heterotrophic respiration (Rh) is an important ecological model parameter and may vary with temperature and moisture. While Q10 generally decreases with increasing temperature, the moisture effects on Q10 have been controversial. To address this, we conducted a 90-day laboratory incubation experiment using a subtropical forest soil with a full factorial...

a fully instrumented air conditioning laboratory unit capable of controlling drying air temperature and humidity integrated with an instantaneous weighing thin layer drying system was used to investigate the thin layer drying behavior and desorption equilibrium moisture content of canola (brassica napus l.). to this aim, freshly harvested canola samples with moisture content of about 12±0.5% (d...

The purpose of this paper is to analyse the impact of surface soil moisture on the spectral reflectance in the optical domain [0.35 15 μm]. This work is based on lab spectral reflectance measurements of bare soils at different moisture contents. Knowledge of surface soil moisture is significant for many applications like trafficability after flood, ground – atmosphere exchanges and plant good h...
