[ 1 ] - تثبیت پتاسیم و ارتباط آن با خصوصیات فیزیکی، شیمیایی و کانی‌های رسی خاکهای آهکی دشت کاکان، استان کهگیلویه و بویراحمد
Potassium fixation is one of the most important factors influencing the availability of this ion for plants. This research was carried out to evaluate the relationship between potassium (K) fixation with some physical and chemical characteristics of soils and clay minerals and to investigate the effect of the dry and wet cycle on potassium fixation in Kakan Plain, in Kohgilouye & Boyerahmad Pro...
[ 2 ] - مطالعه خاک شناسی و تناسب اراضی خاکهای شور و گچی منطقه برم الوان استان کهگیلویه و بویراحمد
هدف از انجام این تحقیق، مطالعه خاکشناسی و تناسب اراضی شور و گچی منطقه برم الوان استان کهگیلویه و بویراحمد به منظور استفاده پایدار از اراضی بود. هدف اصلی از مطالعات ارزیابی اراضی، بررسی خصوصیات اراضی در شرایط اقتصادی موجود برای استفاده بهینه از منابع موجود، به نحوی است که با کسب درآمد معقول، منابع خاک نیز تخریب نگردد. شوری و گچی بودن خاکها دو ویژگی مهم خاکهای تشکیل شده در مناطق پست بوده که با...
[ 3 ] - منشأ و ویژگی‌های کانی‌های رسی و ارتباط آنها با شکل‌های مختلف پتاسیم در خاکهای آهکی دشت کاکان، شرق استان کهگیلویه و بویراحمد
This research was carried out to assess the origin and clay minerals characteristics and their relationship with potassium forms in the calcareous soil of this region, with the humid climate conditions. Based on aerial photos and topographic maps, physiographic units were separated and soil sampling was done in each diagnostic horizon. The results showed that smectite was the main and dominant ...
[ 4 ] - Distribution of zinc and copper chemical forms and their relationship with some physico-chemical properties and clay minerals in some calcareous soils
Determination and recognition of relative distribution of chemical forms of each element and their relationship with physical, chemical and soil clay minerals can help researchers to manage soil fertility better. This research attempted to recognize chemical fractions of zinc (Zn) and copper (Cu) in some surface and subsurface soil samples of Kohgiluyeh and Boyer-Ahmad province and their relati...
[ 5 ] - Effect of different land use on Potassium forms and some soil properties in Kohgiluyeh and Boyer-Ahmad Province, Southwest Iran
The pasture and forest land use change to agricultural use can effect on many properties of the soil and its productivity. The present research aims to investigate various forms of K (soluble, exchangeable, non-exchangeable, and structural forms) and some soil properties in different land use of three areas including Choram, Kakan and Bahmaei in Kohgiluyeh and Buyer-Ahmad Province. Four profile...
