The agri-food market the world over has increased biological, chemical and physical threats to food products, triggering a bigger consumer demand on process control, quality and safety of these products. Bio-sensors can play a vital role in the agricultural and food sectors to control production processes and ensure greater food quality and safety by reliable, fast and cost effective monitoring procedures...
An experiment was performed to examine the physical and chemical effects on high salt-affected soil following the incorporation with four kinds of organic wastes (poultry manure, commercially available fertilizer, reed straw, fresh reed straw with green leaves). Organic wastes were applied at rates of 15g/kg. The effect on the soils physical and chemical properties, soil soluble organic carbon were...
The effect of irrigation of municipal reclaimed wastewater on soil microbial properties in Bei Yechang irrigation area was studied. Reclaimed wastewater irrigation and freshwater is similar to a certain extent can increase the microbial biomass carbon (MBC) under different treatments, rotation treatment increase significantly among these treatments, and almost close to CK. Soil respiration highly...
This study has investigated in a comparative fashion the effect of cations and humus soil on the settling and dewatering of activated sludge. The results from experiments indicate that humus soil could enhance the settling and dewatering properties of activated sludge. Cations leaching from the humus soil played an important role in improving settling and dewatering of activated sludge. Divalent cations,...
In natural attenuation processes, biological soil enzyme activities may change with time and the concentration of the contaminant(s) whose transformation were naturally catalyzed. Short-term irrigation in the laboratory was carried out to evaluate the effect of p-chlorophenol irrigation at different concentrations on soil urease activity of yancheng upland soil. Experiments were conducted on the top...
