Effects of Phanerochaete chrysosporium on biologic activity of soil amended with olive mill wastewaters

Effects of the untreated olive mill wastewater (UOMW) and the bioaugmented olive mill wastewater (BOMW) with the fungus Phanerochaete chrysosporium (P. chrysosporium) for the amendment of soil were investigated. Results showed that UOMW inhibited the soil respirometric activity, while BOMW exhibited significantly higher respiration levels compared to the unamended and the UOMW amended soils. The ratio of...

Simulation of resource-conserving technologies on productivity, income and greenhouse gas GHG emission in rice-wheat system

The Rice-wheat (RW) cropping system is one of the major agricultural production systems in four Indo-Gangetic Plains (IGP) countries: India, Pakistan, Bangladesh and Nepal of South Asia covering about 32% of the total rice area and 42% of the total wheat area. The excessive utilization of natural resource bases and changing climate are leading to the negative yield trend and plateauing of Rice-wheat (RW) system...

Influence of organic matter on the adsorption of sodium dodecylbenzene sulfonate on volcanic ash soil

  Sodium dodecylbenzene sulfonate (DBS), an anionic surfactant, is used as an important content of detergent. Its discharge without treatment causes environmental problem and its adsorptive behavior in soils is not fully understood. In this study, the adsorption behavior of DBS of linear carbon chain on volcanic ash soil was investigated before and after removing most of the organic matter from...
