[ 1 ] - ارزیابی ویژگی‌های آزاد شدن پتاسیم با استفاده از محلول‌های کلرید کلسیم و اسید سیتریک رقیق در برخی از خاک‌های آهکی

Information about potassium (K) release characteristics in the Chaharmahal-va-bakhtiari soils is limited. In this study, K release kinetics of fifteen calcareous soils was investigated. Soil samples were extracted using successive extractions with 0.01 M CaCl2 and citric acid solutions for 2-2017 h at 25±1 0C. Moreover, soil K was determined using 6 chemical extraction methods. The results show...
