Table XII. — Effect of carbon bisulphid and sulphur on the growth of red clover in peat 



soil 



Carbon bisulphid causes a remarkable increase in the growth of clover 

 on peat soil. There is apparently no decided difference in the action of i 

 or 2 per cent of carbon bisulphid. Just why the volatile antiseptic should 

 stimulate so markedly the growth of clover in the peat soil is not known. 

 A more detailed study of the action of carbon bisulphid in peat is now 

 underway. Flowers of sulphur at the' rate of 0.3 per cent proved very 

 injurious. In view of the high sulphur content of carbon bisulphid, it 

 was thought that possibly free sulphur in peat might have somewhat the 

 same effect. 



CORN AND MUSTARD 



The action of carbon bisulphid on corn and mustard in acid soils was 

 studied in an experiment the results of which are given in Table XIII.
