paddy rice residue covers more than 60000 ha of the khuzestan plain. high soil moisture content (low evaporation and heavy soil texture), time limitations, and the likelihood of rainfall make conventional tillage methods unsuitable for wheat cultivation after the rice harvest. the present study investigated the best residue management method, and fuel and time savings, to produce acceptable yie...

background: tetracyclines (tcs) are broad-spectrumantibiotics that are widely used in veterinary medicine. thepresence of tcs residues in milk is a public health concern allover the world. objectives:this study aimed to determine tcsresiduals in pasteurized milk marketed by some dairy companiesin tehran from april 2011 to march 2012. methods: 432pasteurized milk samples were purchased from supe...

Denitrifying bioreactors can be effective for removing nitrate from agricultural tile drainage; however, questions about cold springtime performance persist. The objective of this study was to improve the nitrate removal rate (NRR) of denitrifying bioreactors at warm and cold temperatures using agriculturally derived media rather than wood chips (WC). Corn ( L.) cobs (CC), corn stover (CS), bar...

Residue management in cropping systems is useful to improve soil quality. However, the studies on the effects of residue management on the enzyme activities and microbial community of soils in South China are few. Therefore, the effects of incorporating winter cover crop residue with a double-cropping rice (Oryza sativa L.) system on soil enzyme activities and microbial community in Southern Ch...

This cover image is based on a review article titled “Exploration of Agricultural Residue Ash as Solid Green Heterogeneous Base Catalyst for Biodiesel Production”. In transesterification reactions, heterogeneous solid catalysts are currently replacing homogeneous because their ability to overcome hurdles associated with catalysts. developed from agricultural residues can be used green base cata...
