 per U. S. gallon (3428 parts per million), gave the following results ( 1 ) 



TABLE III. 



Similar results were obtained in comparing two plats which received 

 an occasional heavy irrigation, as may be seen from table IV I 1 ). 



It appears from these two tables that salt accumulated in the soil, 

 besides preventing the normal growth of the cane, also affects its composi- 

 tion in a most deleterious manner. 



It was further shown in the experiments just mentioned that lime 

 applied to soil which is impregnated with salt will help much toward 

 saving the crop; while the growth of the cane is still greatly impeded, 

 its composition becomes normal. The application of nitrogen in the 

 form of dried blood had the same effect as lime. 



Some analyses made in this laboratory also tend to show that a high 

 salt content in the soil depresses the sucrose content and purity of the 

 juice in the cane. The analyses of the respective soils and canes follow :
