[ 1 ] - سهم پتاسیم تبادلی و غیرتبادلی خاک و اجزای رس و سیلت در میزان پتاسیم قابل استفاده گیاه ذرت در تعدادی از خاک‌های لسی و شبه لسی استان گلستان
Determination of relationships between different forms of potassium in soils and their constituents can help us to resolve some nutritional problems such as potassium fixation and release and its fertilization management in soil. This investigation was carried out to determine the contribution of soil and their constituents (clay and silt) Kex and Knex to available potassium for plants in 12 lo...
[ 2 ] - سرعت آزاد شدن پتاسیم غیرتبادلی از خاک و اجزای آن در تعدادی ازخاک‌های استان گلستان
Non-exchangeable potassium (NEK) release is necessary to supply potassium for plant in different soils. A few studies on the NEK release have been done in soils and particularly on its components. This study was intended to investigate the NEK release from soil and the components of clay and silt through successive extractions with oxalic acid (0.01 M) over a period of 1844 (h) in 4 soil seri...
