We have developed a modeling and measurement framework for assessing transport of contaminated soils and airborne particulates into a residence, their subsequent distribution indoors via resuspension and deposition processes, and removal by cleaning and building exhalation of suspended particles. The model explicitly accounts for the formation of house dust as a mixture of organic matter (OM) s...

In situ measurements with visible and near-infrared spectroscopy (vis-NIR) provide an efficient way for acquiring soil information of paddy soils in the short time gap between the harvest and following rotation. The aim of this study was to evaluate its feasibility to predict a series of soil properties including organic matter (OM), organic carbon (OC), total nitrogen (TN), available nitrogen ...

We investigated the effect of organic matter and weathering on the lability and solid phase speciation of heavy metals (Cd, Cr, Cu, Ni, Pb, Zn) in two contrasting subalpine regions in the Italian Alps. Cr, Ni and Cu could be linked to weathering. This was not the case for Pb. Since organic matter (OM) influences the solid phase speciation of heavy metals, the total organic C and N content, the ...

in order to investigation some soil characteristics and filed age effects on flower and corm yield of saffron, an experiment was conducted as factorial based on complete randomized design with five replications in two regions of neyshabur during growing season 2009-2010. treatments were included different filed ages (2, 4 and 6 years) and two geographical regions (eshagh abad and soltan abad). ...

To understand the toxicity of Pb-polluted shooting fields, oribatid mites Platynothrus peltifer were exposed to shooting field soils containing 47-2398 mg Pb/kg dry weight (DW) and having pH(CaCl2) 3.2-6.8 and 3.8-13% organic matter (OM). Exposures also included artificial soils with different pH and OM contents as well as two natural soils used as controls. Exposures lasted for 2 (acute) and 1...

One of the important issues in the analysis of soils is to evaluate their features. In estimation of the hardly available properties, it seems the using of Data mining is appropriate. Therefore, the modelling of some soil quality indicators, using some of the early features of soil which have been proved by some researchers, have been considered. For this purpose, 140 disturbed and 140 undistur...

This paper reports a soil-based bioassay of rice husk bio-ash impacts on redox properties and rice production. Bio-ash was produced during the pyrolytic process of rice husk as a boiler fuel, after which it was applied as an amendment to a flooded soil. Bio-ash was amended before rice transplanting at different mass rates including 0%, 0.1%, 1% and 5%, which was defined as T1, T2, T3, and T4 re...

The use of green nano-amendments is a promising approach for improving soil health and providing sustainable options to reduce root-knot nematodes (RKN) thus increase yields. Therefore, the purpose this research was identify characteristics such as nanobiochar (nB), (GnB), magnetic (MnB) their effect on tomato yield at levels 3 6 mg kg−1 in sandy loam soil. results showed that GnB MnB contain m...

Aim of study: Intensive agriculture impacts physical, chemical, and biological characteristics soil; therefore, the addition organic matter (OM) to soil can have significant implications for crop production. This study investigated impact three management systems on tomato production microbial communities in intensive greenhouse farming.

Soils are viewed in the context of ecosystem services, soil processes and properties, and key attributes and constraints. The framework used is based on the premise that the natural capital of soils that underlies ecosystem services is primarily determined by three core soil properties: texture, mineralogy, and soil organic matter. Up-todate descriptions and geographical distribution of soil or...
