Assessing Relation of Soil Hydrophobicity and Soil Water Content and Determining Threshold Moisture of Organic Soil Samples
Soil water content is the most effective factor associated with the hydrophobic and hydrophilic changes in a soil. Water repellency in soils, is not a permanent feature; it can be reached in the dry season and reduced or eliminated in the wet season It can be said that in terms of moisture, there is a critical region that is defined as the threshold moisture content, where in lower moisture, th...
متن کاملEstimation of Relative Bioavailability of Lead in Soil and Soil-Like Materials Using Young Swine
In this article we summarize the results of a series of studies that measured the relative bioavailability (RBA) of lead in a variety of soil and soil-like test materials. Reference material (Pb acetate) or Pb-contaminated soils were administered orally to juvenile swine twice a day for 15 days. Blood samples were collected from each animal at multiple times during the course of the study, and ...
متن کاملSoil and Water Salinity
Definitions and forms of salinity All natural waters contain soluble salts. The concentration of the salts determines whether the water is of high quality (drinkable or usable for irrigation without need for special precautions) or of low quality (brackish or saline). Water in the soil also contains soluble salts (sometimes called free or nonattached salts). The amount of salts in the root zone...
متن کاملScale Model of a Soil Aggregate and Associated Organisms: A Teaching Tool for Soil Ecology
Soil is a complex habitat for diverse biota. A significant challenge in teaching soil ecology is our inability to observe organisms as they live and interact in the soil. The objective of this article is to describe an interactive class project to help students visualize the sizes of different groups of soil organisms and to relate these to soil structural components. This project was carried o...
متن کاملEstimation of Soil Permeability using Soil Index Properties
Permeability is a very important engineering property of soils and finds utility in a number of soil engineering problems such as yield of wells and seepage through and below the earth structures. It controls the hydraulic stability of soil masses. The permeability of soils is also required in the design of filters required to prevent piping in hydraulic structures. However, the determination o...
