Water quality improvement through bioretention media: nitrogen and phosphorus removal.
High nutrient inputs and eutrophication continue to be one of the highest priority water quality problems. Bioretention is a low-impact development technology that has been advocated for use in urban and other developed areas. This work provides an in-depth analysis on removal of nutrients from a synthetic stormwater runoff by bioretention. Results have indicated good removal of phosphorus (70 ...
متن کاملeffect of seed priming and irrigation regimes on yield,yield components and quality of safflowers cultivars
این مطالعه در سال 1386-87 در آزمایشگاه و مزرعه پژوهشی دانشگاه صنعتی اصفهان به منظور تعیین مناسب ترین تیمار بذری و ارزیابی اثر پرایمینگ بر روی سه رقم گلرنگ تحت سه رژیم آبیاری انجام گرفت. برخی از مطالعات اثرات سودمند پرایمینگ بذر را بر روی گیاهان مختلف بررسی کرده اند اما در حال حاضر اطلاعات کمی در مورد خصوصیات مربوط به جوانه زنی، مراحل نموی، عملکرد و خصوصیات کمی و کیفی بذور تیمار شده ژنوتیپ های م...
relation between the increasing soluble phosphorus and nitrogen uptake and its effects on phosphorus harvest index of black seed
in order to evaluate the effect of increasing soil soluble phosphorus (p) and its effect on nitrogen (n) and p uptake, p uptake efficiency and p harvest index of black seed (nigella sativa l.) in a calcareous soil; a field experiment was conducted as factorial layout based on a randomized complete block design with three replications at research station, faculty of agriculture, ferdowsi univers...
متن کاملPrecision Management of Nitrogen and Water in Potato Production through Monitoring and Modelling
Nitrogen and water application rates and timing depend on the final yield a grower expects the potato crop to achieve. Therefore precise measurements of 1) the nitrogen status of the crop and 2) the water status of the soil are needed. A crop growth model LINTUL-Potato calculates yields and the associated resource requirements based on the temperature dependent length of the growing season, the...
متن کاملGrowth and yield response of potato genotypes to deficit irrigation
In Ardabil region potato crop needs several irrigation, however ground water supplies arebeing exhausted due to reduced precipitation and intensive irrigation. In this research droughttolerance of 10 commercial potato cultivars was studied at three irrigation treatments (100%,80% and 60% of required irrigation water) in Ardabil in a two years field study, 2013-2014.At harvest, marketable tuber ...
