2o6 MAINE AGRICUr.TURAL KX I'KKI MKNT STATION. I9O3. 



lished in tlie Journal of the Royal AgTicullural Society, a publi- 

 cation not available to Maine farmers. The following summary 

 of the results of these experiments on the continuous growth of 

 mangolds for 27 years at Rothamsted is of great value to the 

 practical farmer. 



"Mangolds can be grown continuously on the same land with- 

 out injuring the tilth of the land or the health of the croj). 



"A liberal dressing of farmyard manure forms the best basis 

 of the manure for mangolds. 



"The crop will further respond to considerable additions of 

 active nitrogenous manures to the dung, particularly of nitrate 

 of soda. 



"A free supply of potash salts is essential to the proper 

 development of the mangold, hence a specific potash manuring 

 is desirable even when dung is used in large quantities, and on a 

 strong soil initially rich in potash. When nitrogenous manures 

 are used in addition to dung, the potash salts should be increased 

 pro rata, in order to maintain the health and feeding value of 

 the crop and to bring it to maturity. 



"In conjunction with dung, phosphatic manure is hardly neces- 

 sary and will give little appreciable return especially when the 

 crop is grown in rotation. 



"As soluble alkaline salts are beneficial to the mangold crop, 

 either as direct foods or economisers of potash, a dressing of salt 

 should always be included among the manures for the mangold 

 crop." 



Based upon these findings a liberal dressing for mangolds 

 would be about 5 cords of good stable manure, 500 lbs. nitrate 

 ot soda, 500 tbs. sulphate or muriate of potash, and 200 Vbs. of 

 common salt per acre.
