150 MAINS AGRICULTURAL EXPERIMENT STATION. I904. 



"In conjunction with dung, phosphatic manure is hardly 

 necessary 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 economizers of potash, a dressing of 

 salt should always be included among the manures for the man- 

 gold crop." 



Based upon these findings, a liberal dressing for mangolds 

 would be about 5 cords of good stable manure and the chemicals 

 named in the following formula. 



A FORMULA (NO. 14) EOR MANGOLDS OR OTHER BEETS, BASED 

 UPON EXPERIMENTS AT THE ROTHAMSTED (ENGLAND) 

 EXPERIMENT STATION. TO BE USED IN CONJUNCTION WITH 

 A LIBERAL DRESSING OE FARM MANURE. FOR ONE ACRE.

* Beets are successfully grown in Maine without salt. 



This can be conveniently applied broadcast, separately. To 

 avoid loss by leaching, only part of the nitrate of soda should be 

 applied at planting and the remainder when the plants are well 

 established. To use in machinery, mix with 200 to 300 pounds 

 fine dry muck or loam. 



If stable manure is not used, 40 pounds screened tankage, 400 

 pounds high grade dried blood (250 pounds of sulphate of 

 ammonia can be used instead of the dried blood), and 200 

 pounds acid phosphate can be used to replace the manure. This 

 formula has not been put to a practical test and is based in part 

 upon the plant food requirements of the crop and in part upon 

 the experience at Rothamsted.
