Physical chemistry is the branch of chemistry that establishes and develops the principles of the subject in terms of the underlying concepts of physics and the language of mathematics. Its concepts are used to explain and interpret observations on the physical and chemical properties of matter. Physical chemistry is essential for developing and interpreting the techniques used to determine str...

the effect of poultry waste application on physicochemical and biological properties of sandy clay loam soil was investigated on a 7m x 7m plot of land. plot was divided into four portions and 7.5kg each of broiler, cockerel and layers waste was applied to plot a, b, and c in slurry form while plot d was used as control(no application) for eight weeks with two weeks interval. after the fourth a...

Several studies have shown that soil microorganisms play a key role in the success of plant invasion. Thus, ecologists have become increasingly interested in understanding the ecological effects of biological invasion on soil microbial communities given continuing increase in the effects of invasive plants on native ecosystems. This paper aims to provide a relatively complete depiction of the c...

abstract soil crust decreases soil infiltration and prevents plant stablishment. thus reduction of crust effects is a prominent way to avert desertification. this study was conducted to investigate the effect of polyacrylamide on emergence of canola seedlings in a crusted soil and some physicochemical properties of soil such as ph, ec, sar and bulk density in a field located in date and tropica...

BACKGROUND Assessment of soil arsenic (As) bioavailability may profoundly affect the extent of remediation required at contaminated sites by improving human exposure estimates. Because small adjustments in soil As bioavailability estimates can significantly alter risk assessments and remediation goals, convenient, rapid, reliable, and inexpensive tools are needed to determine soil As bioavailab...

This work was designed to determine the effect of poultry droppings on diesel contaminated soil and evaluate its physiochemical properties. In this study, different ratios of diesel contaminated soil and poultry droppings have been used as raw materials. The mixture of diesel contaminated soil and poultry droppings were allowed to composting process for 40 days. The physicochemical parameters l...

field study was conducted at five villages of botswana namely, tsabong, tshane, mathathane, motlhabaneng and tsetsejwe during the periods of june to august 1999 and june to august 2000. the objective of the study was to assess and compare the soil physicochemical properties of soils at the five villages and to study the effect of cultivation on some soil physical properties. parameters measured...

Burkholderia pseudomallei (Bp), the causative agent of melioidosis, is unevenly distributed in the complex soil environment. Physicochemical factors in the soil have been reported to affect microbial communities in the soil. The effect of physicochemical factors on the number and diversity of organisms in the soil has not been reported. Twenty-five each B. pseudomallei-positive and -negative so...

C. Alister, M. Araya, and M. Kogan. 2011. Effects of physicochemical soil properties of five agricultural soils on herbicide soil adsorption and leaching. Cien. Inv. Agr. 38(2): 243-251. Once pesticides reach the soil, there are several factors that affect their soil behavior. To identify the principal soil and herbicide properties that control their adsorption and leaching, a study of five Chi...
