Summary

Analyzing potassium content in soil by measure of natural gamma radio-activity of ⁴⁰K

Results: output from analyzing potassium content in soil by measure of natural gamma radio-activity was as 2.7-10.4 times as by H₂SO₄ + HClO₄ and as 1.5-3.8 times as by HF + HClO₄ methods. There was correlation between results of analyzing potassium in soil by e=measure of natural gamma radio-activity and by acidic extraction. Based on correlation equations, one can make results of near correlation of total potassium content in soil from analyzing potassium by acidic extraction method.
