In this work, an activated sludge lab-scale reactor used for nitrification was monitored by specific activity kinetic assays. The nitrification biomass activity was carried out by respirometric methods in order to characterize the inoculum and the reactor... see more

Incorporation of rice straw into soil is a common practice to improve soil productivity and increase inorganic fertilizer availability. However, this practice could contribute to methane (CH4) emission; one of the greenhouse gases that causes global warmi... see more

Agricultural chemicals have been used extensively in modern agriculture and toxicological studies suggest a great potential for inducing undesirable effects on non target organisms. A model experiment was conducted in order to determine side effects of th... see more

Conclusions. For the wide use of biofilters to remove nitrogen compounds from drinking water, it is necessary to seek ways to improve their work by replacing the biological agent, intensifying nitrification-denitrification processes, using mutant strains ... see more

Nitrogen (N) fertilizer efficiency can increase by adding N-(n-butyl) thiophosphoric triamide (NBPT) and N-(n-propyl) thiophosphoric triamide (NPPT) as urease inhibitor in urea fertilizer and adding 3,4-dimethyl pyrazole phosphate (DMPP) as nitrification ... see more

An incubation experiment was conducted to evaluate the effect of aqueous extracts of 17 plant materials on nitrification inhibition of urea- N in soil as compared with chemical inhibitor Dicyandiamide (DCD). Plant materials used in study were collected fr... see more

Tomato bacterial canker and wilt is a destructive disease causing economic losses and affecting plant growth and yield. Due to the lack of disease resistant cultivars and non- effective chemicals, management of the disease is quite tricky. The aims of thi... see more

This work evaluates the process of nitrogen removal from wastewater at a meat processing plant, using nitrification and denitrification in bioreactors. The system was composed of two reactors with continuous flow operated in series: a hybrid reactor (anae... see more

Nitrogen (N), the most critical and essential nutrient for plant growth, largely determines the productivity in both extensive and intensive grassland systems. Nitrification and denitrification processes in the soil are the primary drivers of generating r... see more
