Biological treatments focused on stabilizing and detoxifying olive mill wastewater facilitate agronomic reuse for irrigation fertilization. Anaerobic digestion is particularly attractive in view of energy recovery, but severely hampered by the microbial toxicity wastewater. In this work, addition biochar to mixture was studied improve stability efficiency anaerobic process. Kinetics yields biog...

The nitrification inhibitor, dicyandiamide (cyanoguanidine) (DCD), can improve fertilizer N efficiency; however, yield reductions and phytotoxicity from the use of DCD have been reported. A green­ house experiment was designed to determine the effect of DCD on growth, chlorophyll concentration and nutrient concentration of corn ( Zea mays L.), cotton ( Gossypium hirsutum L.), and grain sorghum ...

Environmental problems associated with non-ferrous smelter operations are a problem in many countries around the world. Copper production Armenia has resulted metal contamination of soils and general degradation environmental quality. In this study we attempted to determine thresholds phytotoxicity metals contaminated by copper Armenia. The studied were sampled Alaverdi valley, located ~200 km ...

With the emergence of agriculture, humankind faced numerous difficult tasks. For example, how to use potential soil while saving its quality and functional properties, apply agricultural technologies effectively environmentally friendly, make them safe for human health biota, many others. There are several informative reliable recording criteria indicator systems that fully comprehensively desc...
