SOIL INOCULATION 



there numerous nodules upon the roots, but 

 the upper part of the plants above ground aver- 

 aged about three feet in height ; few branches 

 of the non-inoculated plants were as long 

 as eight inches. The two soils, aside from the 

 inoculation, were treated in precisely the same 

 way. In green forage, the inoculated plot 

 yielded nine thousand, one hundred and thirty- 

 six pounds per acre; the one not inoculated, 

 nine hundred pounds. In cured hay, the inocu- 

 lated yielded two thousand, five hundred and 

 forty pounds; the other, two hundred and 

 thirty-two pounds. The increased yield of hay 

 was nine hundred and ninety-five per cent, 

 due to inoculation. Other tests, taking soils 

 from different parts of the state and submit- 

 ting them to laboratory growing, abundantly 

 proved the wonderful advantage of inocula- 

 tion. Pot experiments were carried on with 

 crimson clover, also a plant which had largely 

 failed in Alabama. On thirty farms the clover 

 had been tried with unsatisfactory results, and, 

 in the majority of cases, the roots examined 

 showed a total absence of tubercles. A few 

 specimens showed a very few quite small 

 tubercles. The crimson clover on the farm of
