On the fen area of the Experimental Station of Leteensuo, with a peat layer consisting of forest sedge peat, potassium fertilization produced a considerable increase of the hay crop yield on the clayed as well as the unclayed bog, when phosphate fertilization had been added. However, clay displayed a considerable potassium fertilizing effect and also other effects, which probably cannot be reproduced by fertilization. The effect of potassium fertilization on the summer cereal crop yield was different in different tests. In two of them, potassium fertilization increased the grain yield but not in the third. The results obtained in this latter instance are thought to have been influenced by the addition of mud through the action of floods. Po...
