BARN FIELD 



Mangel Wurzel 



The experiments upon mangels began in 1876, but the land had been 

 receiving similar manures for other root crops since 1856. 



The field is divided longitudinally into eight strips running the whole 

 length of the field ; each of these strips receives one manure throughout its
