EXPERIMENTS IN SOIL MANAGEMENT 



AND 



FERTILIZATION OF ORCHARDS 



By J. K. SHAW 



This bulletin reports the results of the application of four 

 different fertility practices to an orchard containing four 

 varieties of apple trees, and subjected during the course 

 of thirty years to three significantly different cultural 

 practices. 



This work is checked by a study of a second orchard on 

 a different soil type, where practically the same plant-food 

 combinations were used on a single variety grown under 

 a single definite cultural treatment.
