Absorption and fluorescence properties of 4 hydraulic oils (3 biological and 1 petroleum-based) were investigated. In-situ LIF (laser-induced fluorescence) analysis of the oils on a brown sandy loam soil was performed. With calibration, quantitative detection was achieved. Estimated limits of detection were below ca. 500 mg/kg for the petroleum-based oil and ca. 2000 mg/kg for one biological oi...

Introduction Before we can understand the role of amendments and additives to the soil and their part in a healthy soil, we need to understand what is in the soil and role of some of the organisms in the soil. By knowing something about soil biology we can get a greater appreciation of the constraints and challenges presented by the use of amendments and additives to the soil. This article is n...

A variety of microfauna inhabit the biological soil crusts (biocrusts) of arid soils from all parts of the globe, including the southwestern USA (Bamforth 2004, 2008; Darby et al. 2006, 2007a, b; Neher et al. 2009), the Negev Desert of Israel (Jones and Shachak 1990; Pen-Mouratov et al. 2011), the Tengger Desert of northern China (Liu et al. 2011; Li et al. 2011), Australia (Robinson et al. 200...

The effects of salt precipitation on water and heat transport in soil have garnered considerable attention. However, growth the surface its influence evaporation temperature under a fixed groundwater table are not well understood. Therefore, objective this study was to investigate impact evolution sandy soils with depth (20 cm). laboratory experiment consisted two treatments for sand columns: o...

application of superabsorbent material is one of the new methods for moisture storage in the soil. this research was performed in the khajeh research station on the basis of randomized complete block design with three replications in the plots with dimension of 4×5 meter for investigate the effect of different amounts of pumice on water retention capacity in the soil, growth and of spring saffl...
