An experiment was conducted at the Soil Science Field Laboratory of Bangladesh Agricultural University, Mymensingh during November 2011 to March 2012 to evaluate the effect of integrated use of manures and fertilizers on the growth, yield and nutrient uptake by wheat. There were six treatments such as T0 (Control), T1 [STB-CF (HYG)], T2 [CD + STB-CF (HYG)], T3 [PM + STB-CF (HYG)], T4 [COM + STB...

Large amounts of fertilizers and pesticides applied annually to agricultural soils improve the physical and chemical properties of soil but, when they are applied without control they can cause serious environmental problems. The farms of Tizayuca in Hidalgo State produce about 30000 tons of manure per day, which are applied indiscriminately in the same region for agricultural use. The aim of t...

Understanding the removal mechanisms and kinetics of trace tetracycline by activated sludge is critical to both evaluation of tetracycline elimination in sewage treatment plants and risk assessment/management of tetracycline released to soil environment due to the application of biosolids as fertilizer. Adsorption is found to be the primary removal mechanism while biodegradation, volatilization...
