Heavy metals contamination threat to the environment is a big concern. Predicting the movement of heavy metals such as Cd in soil is an important goal. In this study the effect of soil chemical and physical properties on Cd mobility were done using a thin layer chromatography (Soil TLC). The soils used in this research have a wide range of organic matter (2.1-29 g/kg), pH value (4.9-8.8), CEC (...

Food security in the East African Highlands is dependent upon the productivity of lands managed by smallholders who face difficult challenges in maintaining the fertility of their soils. A study was conducted to identify indicators of soil fertility status that are consistent with farmers’ perceptions of soil fertility. Physical, chemical and biological properties of soils were measured from pa...

to evaluate the effects of fertilizing and deficit irrigation regimes on some chemical properties of soil and plant, an experiment was conducted during 2007 and 2008 growing seasons. experimental design was a split plot based on a randomized complete block design with four replications. the treatments consisted of three deficit irrigation regimes (main plots) and six soil fertilizing systems (s...

in this study, micromorphological properties of some samples collected from pedons polluted with petroleum refinery wastes and some adjacent unpolluted pedons were studied. after description of the studied pedons, disturbed and undisturbed samples were collected for physicochemical and micromorphological analyses. the results showed that the physicochemical properties (i.e. structure, bulk dens...

Marton (Argillic Perched-gley Pallic, Typic Endoaqualf), Ohakune (Typic Orthic Allophanic, Typic Hapludand), and Westmere (Mottled Mafic Melanic, Mollic Hapludalf) soils with differing structural vulnerability were compared at matched sites under different land uses. Topsoil samples (0-10 cm) from indigenous forest (>50 yr), permanent pasture (>50 yr), pine plantation (>20 yr), or arable croppi...

soil hydraulic properties are key soil physical characteristics that are required to conduct soil and water related studies such as irrigation and drainage. in this study, three indirect methods: inverse modeling, pedo-transfer function, and the semi-physical method of arya et al., were compared in a sandy loam soil to estimate soil moisture retention and unsaturated hydraulic conductivity curv...

The objective of this work was to study the effects of tillage and liquid manure applications on some physical and chemical properties as well as on the carbon and nitrogen mineralization potential of a meadow soil. Our results indicated that tillage and manure applications had no effect on the concentration of Cu, Mn, total N and organic C in 0-15 cm layer of soil after 15 years of treatment. ...

this research delves into investigating the effects of different soil management practices on soil physical properties, yield and yield’s components of irrigated wheat. this experimental design was administered in the form of the nested testing with three treatments (no tillage, low tillage and conventional tillage) and three replicates in some of the farmlands of chenran township. the results ...

ground skidding on skid trails affects the physical properties of soil. the objective of this study was to evaluate changes in soil physical properties on skid trails formed due to traffic of metal-tracked skidders with regard to soil bulk density, total porosity, water content and penetration resistance. the studies were implemented on two levels of slope – 20% (sc2) – and three levels of traf...
