One of the important commodities that are widely consumed to meet nutritional and food needs, especially vegetables, is tomato (Solanum lycopersium). The need for tomatoes increasing both in quantity quality. But until now vegetables quality difficult using conventional agriculture. For this reason, application biological fertilizers have potential reduce use inorganic able efficiently fertiliz...

biofiltration of triethylamine (tea) vapor used as a catalyst in casting operations was evaluated in this study. the unit consisted of a 6-l three-stage biofilter containing a mixture of compost and wood chips (40:60 v/v) as the filter medium. seed microbial population from municipal activated sludge was acclimated for a period of three weeks prior to the actual experimental runs. in the startu...

A field study was conducted in northern France over two consecutive years to evaluate the combined effect of conventional tillage (CT) vs no till (NT) with or without cover crops (cc) and nitrogen (N) fertilization on various agronomic traits related to N use efficiency in winter wheat. Five years after conversion of CT to NT, significant increases in N use efficiency, N utilization efficiency,...

Removal efficiency of COD, NH4-N and PO4-P and NO3-N in five step SBR processes is widely influenced by hydraulic retention time of Anaerobic/Anoxic/Aerobic/Anoxic/Aerobic step of this system where the hydraulic retention time in each step is influence directly on removal efficiency of this system therefore the operator of this system cannot control on this system without experience or a contro...

the aim of this study was to evaluate the effects of tannic acid (ta) and pistachio by-product tannin extract (pbe) on n utilization and efficiency of microbial nitrogen synthesis (emns) in saanen dairy goats. the experimental design was a change over design with three treatments and three periods using six mid lactation multiparous dairy goats. tannic acid solution and pbe were added to fresh ...
