Potasyum - Yaşam için Mutlak Gerekli bir Element Potassium - a Nutrient Essential for Life
Potasyum Dünyadaki yaşam için anahtar bir element niteliğindedir. Tüm bitkiler ve hayvanların yüksek miktarda gereksinim duydukları bu elementi, bitkiler gelişme ortamları olan topraktan elde etmektedirler. Hayvanlar ise potasyum gereksinimlerini bitkiler aracılığı ile karşılarlar. Bunun için ya doğrudan bitkileri tüketir, ya da bitkilerle beslenmiş olan diğer hayvan ve hayvansal ürünleri yiyerek K'u elde ederler.
