Lack of knowledge on soil geotechnical properties can cause many problems in the construction and maintenance of irrigation and drainage networks. In general, all of unconventional soils such as gypsiferous soils can cause some problems to irrigation canals. Some studies have been conducted on a variety of problematic soils, but still there is a need for more research activities and field studi...

Laboratory tests were conducted to determine the effect of soil gas oxygen concentration on the degradation and mineralization of spiked C-pyrene and nonspiked 16 priority pollutant polycyclic aromatic hydrocarbons (PAHs) present in the soil. The soil used for the evaluation was taken from a prepared bed land treatment unit at the Champion International Superfund Site in Libby, Montana. This so...
hydraulic attributes play important role in hydrological studies, soil conservation, designing irrigation and drainage systems, soil conservation, and controlling soil erosion in watersheds. their measurements are very tedious and time consuming and due to high spatial variability, a large number of measurements are required for obtaining reliable values. nowadays, prediction of these attribute...
The persistence and stability of free plasmid pUC8-ISP DNA introduced into 10-g samples of various soils and kept at 23 degrees C were monitored over a period of 60 days. The soils were sampled at a plant science farm and included a loamy sand soil (no. 1), a clay soil (no. 2), and a silty clay soil (no. 3). Four different methods allowed monitoring of (i) the production of acid-soluble radioac...
