June IS, 191S Antagonism between Anions as Affecting Barley 217 



(2) In testing the toxicity of single alkali salts it is found that o.i per 

 cent each of sodium chlorid and sodium sulphate stimulates barley in the 

 first crop and reacts poisonously to it in the second crop. 



(3) Sodium carbonate does not manifest toxicity, but, on the contrary, 

 shows stimulation even up to concentrations equal to 0.3 per cent of the 

 dry weight of the soil.
