nourishment that enables it to withstand otherwise toxic effects 

 that might check growth if such nourishment were not avail- 

 able (see also page 34).

 concentration. Under normal soil conditions and with the 

 normal applications of practical agriculture there are no un- 

 usual effects on the germination of the seed or on the growth 

 of the plant. This is verified constantly in the extensive use 

 of Cyanamid in agriculture.
