8 Experiments with Humogen. 



SERIES I continued. 

 TESTS WITH RED CLOVER. 



Seed sown June 9. In each case the weight of the plants when cut on 

 September 14 is given in the following table. 



OBSERVATIONS RECORDED DURING GROWTH. 



June 19. On the seedlings appearing, no difference was discernible 

 between the various sets, with the exception of the Rito tests which were 

 very thin and backward in growth. 



July 8. In those instances where Complete Fertiliser and Rito had been 

 used, the plants were noticeably backward as compared with the plain soil 

 Control, Farmyard Manure, Humogen, and Common Burning Peat tests. 



July 24. The Complete Fertiliser trials were now rapidly improving 

 and appeared to be recovering from the apparent check sustained in the first 

 stage of growth. Humogen test (30%) was extremely poor, being thin, 

 stunted, and yellow in colour ; sets dressed with Humogen (5%) showed a 

 decided superiority over those dressed respectively with 20% and 10% of this* 

 fertiliser. 



August 6. With the exception of the Humogen test (30%), which had 

 not in any way improved, there was no great difference to be seen in any 

 of the trials. The plain soil Control was certainly as good as the others. 



September 14. The plants were cut and weighed.
