Water Quality Modeling and Evaluation of Nutrient Control Strategies Using QUAL2K in the Small Rivers
Background: Qual2k is a stream water quality model and was used to evaluate the water quality of the Kine-Vars River and assess the response of the river to nutrient management strategies. Methods: For that purpose, 7 sample stations were selected and surface water samples were collected in the winter and summer of 2012 and were analyzed for temperature, dissolved oxygen, biological oxygen dem...
متن کاملاثر برهمکنش نیتروژن و مواد آلی بر رشد و عملکرد گندم دیم ( Triticum aestivum)
In order to evaluate the interaction effects of nitrogen and organic matter on growth and yield of dryland wheat, an experiment was conducted at the research station of the College of Agriculture, Shiraz University at Bajgah in 2005 and 2006. The experimental design was split plot in which three levels of nitrogen (0, 40, and 80 kg N ha -1) were main factors and additive organic matters includi...
متن کاملمعدنی شدن کربن و نیتروژن آلی بقایای گندم در خاکهای آلوده به سرب
To assess the effects of different levels of soil lead on mineralization of organic carbon and nitrogen, a factorial pot experiment was conducted using litter bag method. The factors examined were different levels of soil lead (0, 25, 50, 100, and 200 mg kg-1soil) and incubation periods (1, 2, 3 and 4 months) in three replications. At the end of incubation periods, the litter bags were pulled o...

متن کاملNitrogen management strategies for maize production systems: Experimental data and crop modeling
Maize (Zea mays L.) is an important crop among Brazilian smallholder farmers,who are also responsible for 40% of the poultry and egg production in the country.Although poultry litter is considered a potential pollutant, if properly stabilized anddistributed in the field it can be used as a source of nitrogen for maize production.In this study, the response of maize to mineral fertilizer and pou...
