Abstract: The role of pure or semi-pure mineral elements has changed in the nutrition of agricultural soils during the 20th century. According to an old database potassium mineral fertilizers, K.fm, composed in the 1920’s ca 8 % and manure (recycled, rcl), K.rcl ca 92 % of the total potassium fertilization (K.ft). In the 1970’s the proportion of K.fm increased upto little over 70 %. About similar increase occurred in other main mineral nutrients (N, nitrogen and P, potassium).
