Favourable results have also been obtained in Italy, as will be seen from 
the following experiments :—

The addition of potash considerably increased the yield in all three cases 
over that obtained from a combination of nitrogen and phosphoric acid. 
Sulphate of potash produced the greatest benefit upon the yield of ear-corn, 
muriate of potash upon that of straw. Even when the soil is naturally rich, 
the yield of corn will be increased by artificial fertilisation, as can be readily 
seen from the results of experiments conducted last year by Mr. L. W. West, 
of Hadley, Massachusetts.* 
The soil was a heavy-loam, hard-pan bottom. No lime was applied, as this 
ingredient had produced no appreciable effect in previous years.
