The effects of soil rare earth element (REE) on navel orange quality and safety in rare earth ore areas have gained great attention. This study investigated the transfer characteristics of REE from soil to navel orange pulp (Citrus sinensis Osbeck cv. Newhall) and examined the effects of soil REE on internal fruit quality in Xinfeng County, Jiangxi province, China. Path analysis showed that soi...

1 We studied the interaction between the naturally occurring polycation spermine (SPERM) and 2 Na-exchanged SWy-2 Wyoming montmorillonite (Na-SWy-2 Mt) and between spermine3 exchanged montmorillonite (Mt-SPERM) and the herbicide fluometuron. Mt-SPERM with 4 spermine contents ranging between 0 and 1.2 times the cation exchange capacity (CEC) of 5 Na-SWy-2 were studied by XRD, FTIR and TGA analys...

Bioavailability is a critical facet of metal toxicity. Although past studies have investigated the individual role sediment physico-chemical properties in relation to bioavailability heavy metals, their collective effects are little-known. Further, limited knowledge exists on contribution nutrients bioavailability. In this study, influence sediments, including total organic carbon (TOC), phosph...

In phytoremediation processes implemented in highly contaminated areas, there is a high risk of contaminant toxicity during the germination freshly sown plants. such conditions, it recommended to support by using neutralizing additives. The present study aimed at assessing effect addition mineral neutralizers (MNs), i.e., limestone, clay, and zeolite, soil with copper (0, 200, 400, 600 mg kg−1)...

Utilizing rice hulls as growing media is commonly practiced. However, it had low valued of Water Holding Capacity (WHC) and Cation Exchange (CEC) which caused considered a quality for plants. Based on previous study, pyrolysis could alter physical chemical properties to form char. The aim this study was evaluate process by compare properties. This research conducted at two peak temperatures (45...

This study conducted in Aljabal alakhdar (Green Mountain), Derna, Libya. It is the only wet region Like other Mediterranean forests, it exposed to risk of fires. To assist this, two different geographical units from (coastal and mountain), which been burned at times; identify whether these soils are regaining their pre-burn status over time. The studied properties were: soil clay content, organ...

The knowledge of agricultural soil properties is crucial for the auspicious selection crop, irrigation and fertilization types. This study contains results field laboratory application electrical measurements used to obtain fines content, porosity, hydraulic conductivity cation exchange capacity (CEC) in three plots purpose growing barley. values content were attained using samples Ryjov's algo...

The use of exclosure for ecological restoration has become an increasingly vital approach to reversing degraded lands. Its effectiveness in restoring lands could be varied with differences climate, vegetation type and soil properties. Thus, the objective this study was determine effect on selected physical chemical properties soil. A six-year-old adjacent open land same history land-use types w...

Low salinity water injection (LSWI) is an emerging way to improve waterflood performance through chemical processes. The presence of clay minerals one the required parameters successfully implement LSWI in sandstone formations. ability clays exchange cations, represented by cation capacity (CEC), leads oil detachment from rock surface and changes formation wettability toward water-wet. There ar...

Successful fertilization treatments targeted to improve stand productivity while reducing operational complexities and cost depend on a clear understanding of soil nutrient availability under varying environmental conditions. Soil data collected from 154 forest sites throughout the Inland Northwest, USA were analyzed examine characteristics different geologic parent materials rank fertility. Re...
