SOY BEANS. 



Six crops of Mammoth Yellow soy beans were grown. The plants 

 were harvested in flower, while the leaves were still sound. The ab- 

 solute and relative growths made on the four plats are given in 

 Table VIII. 



Table VIII. — Growth of soy beans on plats with different amounts of CaCO^. 



The average results show that the best growth of soy beans was 

 made on the plat with no carbonate of lime; there was, allowing for 

 the probable error, an 8 to 12 per cent decrease on Plat II, a 17 to 

 21 per cent decrease on Plat III, and a 2 to 8 per cent decrease on 

 Plat IV. 



Crops A, B, and C were analyzed together in a composite sample 

 containing equal parts of the three crops, and crops D, E, and F 

 were analyzed in another comj^osite sample. The results are shown 

 in Table IX.
