Potash facts. Potash is the common name given to a group of minerals and chemicals that contain potassium (chemical symbol K), which is a basic nutrient for plants and an important ingredient in fertilizer. Most potash is produced as potassium chloride (KCl). However, we often measure and refer to it in terms of potassium oxide (K2O ...

The extraction of soluble salts (as potash) from four ash samples from cocoa pod husks yielded material with an average potassium content of 44.3 ~. This value agrees fairly well with that found for the K + ion content of the ash, which was 43-5 ~o (average of 10 samples). The slightly higher value obtained from the extraction could be ...
