Tillage practices can influence crop root development. Root distributions were determined for wheat (Tdicum aestivum L.) grown in a wheat-fallow rotation during the 1977-1978 winter wheat crop year on an Alliance silt loam (Aridic Argiustoll). The fallow tillage treatments were plow, subtillage, and chemical (no tillage). Each tillage treatment was split into subplots for N application of 0 or ...

This study presents the experimental remediation studies of diesel contaminated soil with Sodium Deducible Sulfate (SDS) as surfactants using column tests. Sandy selected soil had the grain size distribution of # 40 meshes to the # 200 mesh range. The soil columns were contaminated with adequate diesel amount to achieve the concentration of 10000 and 20000 ppm in soil. 0.1, 0.2, 0.3, 0.4 percen...

Rapid industrialization in the 1960s caused heavy metals such as cadmium (Cd) to severely pollute soil in Japan. The Agricultural Land Soil Pollution Prevention Law was enacted in 1970 to cope with the heavy metal pollution. Cd, in particular, has been recognized as one of the most detrimental elements in Japan because of the so-called “itai-itai” disease caused through Cd uptake. Recently, the...

soil washing by mobilizing is one of in-situ techniques for soil decontamination. applying this technique to the contaminated soils could be followed by many environmental problems. therefore, it is important to study the effective factors on removal of heavy metals from different forms. in the present research, the forms of zn, pb, and cd in three contaminated soils from the zinc-lead smelting...

Our previous study indicated that the current level of polycyclic aromatic hydrocarbons (PAHs) in Shenzhen soil is in the low-end of world soil PAH pollution. In this study, the fate of PAHs in the soil of Shenzhen was investigated. The mass inventories of Σ(27)PAHs and Σ(15)PAHs (defined as the sum of the 27 or 15 PAH compounds sought) in topsoil of Shenzhen were ∼204 and ∼152 metric tons, res...
