Abstract

Land degradation, with declining yields and the reopening of agricultural land yields, is a global concern. Soil salinity and sodium content is one of the main causes of land degradation, which has affected a large part of the arid and semi-arid surface. Management of saline and sodium soils was considered as a major challenge due to unfavorable physical, chemical and microbial properties, which achieved soil quality and crop productivity. Rehabilitation of lands that can be killed and worked on, but have salinity and sodium limitations, is inevitable. Different methods have been used to improve the soil of saline and sodium areas. These methods include the use of organic and inorganic modifiers. This study intends to evaluate the salinity and sodium content of saline and sodium soils in Ardabil region, the effect of the efficiency of each modifier (gypsum, inforic acid, fungal compost, manure and leaching) on the control of salinity and sodium content of soils And to evaluate the improvement of physical and chemical properties of soils. Therefore, this study investigates the effects of inorganic and organic modifications and its combined effects on the properties of saline and sodium soils with the aim of: 1) comparing the efficiency of organic and inorganic modifiers; 2) The effects of organic and inorganic modifiers on soil physical and chemical properties were investigated.

Persian Title: بررسي توانايي اصلاح کننده‌هاي آلي و معدني در اصلاح خاک‌هاي شور و سديمي دشت زرناس اردبيل
Persian Abstract: شور و سديمي شدن خاک‌ها بعد از فرسایش دومین عامل تخريب اراضي است که بخش وسيعي از مناطق خشک و نيمه خشک جهان از جمله ایران را تحت تأثير قرار داده است. مدیریت و بهسازی خاک‌های شور و سدیمی به دلیل خواص نامطلوب فیزیکی، شیمیایی و میکروبی یک چالش جدی جهانی بوده و منجر به کاهش حاصلخيزي، کیفیت و بهره‌وری خاک می‌شود. لذا، اصلاح و احيا اراضي این خاک¬ها امري اجتناب ناپذير است. در اين پژوهش، تأثير افزودن گچ کشاورزی به تنهایی و به همراه کمپوست و کود دامی همچنین، تاثیر اسید انفوریک بر اصلاح خصوصیات یک خاک شور و سدیمی مطالعه شد.
