Scientists from Tomsk Polytechnic University are studying the mineral glauconite as an eco-friendly and effective alternative to traditional potassium fertilizers exploited in agriculture. Their recent study showed that glauconite-bearing rocks can be as efficient as traditional fertilizers to increase the wheat yield even with minimum soil cultivation. Glauconite also does not leave any harmful elements in the soil like chlorine and is able to release potassium during several agricultural seasons. The study results were presented in the journal Applied Clay Science.
