Mouth-to-mouth analysis methods are important for determining soil potassium levels. Methods based on soil analysis mainly use 1M ammonium acetate (pH 7.0) and 1M neutral ammonium chloride solution. Some modern methods also utilize spectroscopic methods for accurate results. Evaluating the potassium content in soil, meeting the nutritional requirements of plants, and increasing their productivity are important factors. Sources indicate potassium levels in the range of 40-500 mg/kg, depending on various interactions and soil composition
