BARN FIELD 



Mangolds. 



The experiments upon mangolds 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 length ; farmyard manure alone on Strip 1, and in combination with 

 superphosphate and sulphate of potash on Strip 2, nothing on Strip 8, 

 superphosphate alone on Strip 5, superphosphate and sulphate of potash
