Polyacrylamide for Surface Irrigation to Increase Nutrient-use Efficiency and Protectwater Quality
Furrow irrigation systems have a greater application capacity, are less costly, and use less energy than sprinkler systems but furrow irrigation produces greater runoff, erosion, and deep percolation losses. Phosphorus (P) and nitrogen (N) losses are associated with runoff sediment, and can be minimized by eliminating irrigationinduced erosion. Excessive leaching of inorganic and organic solute...
متن کاملevaluation of irrigation water management and boron fertilizer to increase water use efficiency of sugar beet
this study evaluated the irrigation water management and different amounts of boron fertilizer affacts on yield and and water use efficiency of sugar beet. the two-factor factorial design in randomized complete block with three replications of irrigation and different levels of boron fertilizer for three years (2000-02) was designed in qazvin. the main four irrigation treatments were t1, t2, t3...
متن کاملSurvey of surface runoff quality in Zahedan for irrigation usage
Background & Aim: Urban runoff is one of the most valuable and renewable water resources in many arid and semi-arid parts of the world. Understanding how to use these resources is very important. The purpose of this study was to determine the physical, chemical and biological properties of surface runoff in Zahedan for irrigation uses. Methods: The present work was a descriptive cross-sectiona...
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...
Erosion control practices integrated with polyacrylamide for nutrient reduction in rill irrigation runoff
The objective of this research was to assess soil conservation practices for improving water quality of return flows from rill irrigation in the Yakima River Basin, Washington, by combining patch application of polyacrylamide (PAM) with an additional erosion control practice. A 2-year field study was conducted that combined PAM with (1) check dams, (2) surge irrigation, (3) surface drains, and ...
