From the above table it maybe seen that potash had the most marked 

 iiitliieiice in augmenting the yield of dry matter, while nitrogen was 

 less effective. " Unlike the grasses, the legumes seem to be but little 

 affected in their protein or nitrogen content by the addition of nitrogen 

 ill the fertilizers. Potash appeared to have the most marked influence 

 [in augmenting] the percentage of protein in the crop." 



Experiments with flax in Belgium, P. de Caluwe {Expose Cult. 

 E.iph-. Jard. Gaud, 1892-93, pp. 30-30). — Experiments with varieties 

 and a test of different forms of phosi>horic acid. On flax, as on lupines, 

 superphosphate in a dry season reduced the yield.
