mineral plant-foods. This subject will be 

 studied with special reference to the fertilizing 

 action of superphosphate in conjunction with 

 green manures. 



(5) Soil Toxins. Bacterio-toxins occurring in soils; 



their influence on nitrification and the condi- 

 tions conducive to their formation and destruc- 

 tion; this study is especially connected with 

 the practice of green manuring and the use of 

 organic manures in badly drained soils. 



(6) Study of conditions under which saltpetre is 



formed in Bihar soils. 



(7) Biological analysis of soils; a further study of 



the best means of carrying out this method of 

 investigating soil conditions; this subject forms 

 a principal part of the training of students in 

 this section, the earlier stages being especially 

 designed to allow of familiarization with the 

 methods of obtaining information as to the 

 biological conditions in a soil without under- 

 going a course of training in purely bacteriolo- 

 gical technique. 



Minor Subjects. 



Study of organisms connected with fermentation. 

 Such cases of bacterial disease of plants as may arise.
