PAKMELEE EXPERIMENT FARM — INGHAM COUNTY. 



The Parmelee farm is an example 'of severe cropping and injudicious "running" that 

 is seldom seen in central ]\Iichigan. The soil is naturally a very light sand which 

 suffers severely during the siimmer droughts. The humus is entirely exhausted, while 

 the open, sandy condition of the soil has encouraged complete waste and leaching of 

 the elements of fertility. Throughout the early growth of the crops there was a mani- 

 festly greater development on tlie plots receiving nitrogenous feitilizers, but the dry 

 weather so completely burned the soil and crops that the final yield in no way indicates 

 the needs of this soil. The experiment is being continued with the hope of more satis- 

 factory results.

The writer did not visit this field. The uiiiformiiy of the results and the very 

 slight benefit arising from the application of liberal amounts of commercial fertilizers 

 suggests the same difficulty that is ai)parent in connection with many of the other 

 fertilizer experiments conducted during this season. In order that anv plant food 

 may l>ecome useful to a growing crop there must be a sufficient amount of rainfall
