this may be due to the fact that in the soil used the aeration was very 

 good and the meal decomposed with sufficient rapidity to supply the 

 demands of the crop. On heavier or wetter soils the results might be 

 quite different. 



The author states that if these results are confirmed by further 

 experiments an extended field for the profitable use of one of the cheap- 

 est sources of phosphoric acid, degelatinized bone meal, will be opened 

 up; for it appears to be as effective as the best forms of phosphoric 

 acid on sandy soils and may largely replace Thomas slag on such soils.
