MANURE FOR TURNIPS. 193 



golds — should be put in the drills. That is the best way a crop 

 of mangolds can be raised. Salt for mangolds. I have used 

 forty bushels of fine salt to the acre, composted with manure. 

 That, put into the drills, will always give you a good mangold 

 crop, unless the skies arc adverse. 



Thoroughly decomposed manure for carrots. They will grow 

 just as Mr. Thompson said, if you put on green manure. 



For turnips a small quantity of nitrogenous manure and of 

 vegetable decomposed manures ; not a large quantity, but phos- 

 phates. Turnips require phosphates ; that is a rule you can 

 apply. Why they require phosphates is more than I can tell ; 

 but they do. You can apply your phosphates in any way you 

 see fit. Not an extra quantity of coarse manures, not an extra 

 quantity of animal manures, but phosphates in some form or 

 other. These are the manures for roots. 



I have got the land ploughed and manured, and Mr. Ware 

 has told you how to prepare your seed and sow them. Now you 

 have got the crop off, we will suppose, and what is the condition 

 of your land ? It is just in the condition of all land from which 

 you have taken a tremendous crop of anything — whether corn, 

 tobacco or anything else. You cannot raise a great crop of 

 anything, (and you do not want to raise a poor crop,) without 

 exhausting the land to some extent. The raising of root crops 

 demands superior cultivation. I use the common phrase, 

 " exhausting the land." W T hat the roots do to the land I do not 

 know, but they do put the land in such a condition that it 

 requires extra cultivation to bring it back again ; and extra 

 cultivation, I believe, will be more than repaid. 



Mr. Stockbeidge. Supposing on one side of a field you sow 

 turnips, and on the other plant potatoes, preparing the land 

 properly for each crop, and then follow those crops with corn, 

 which will injure the land most ? 



Dr. Loeing. I should be slow to follow either with corn. I 

 don't think I would plant corn after potatoes, or Swedish 

 turnips, or any turnips. The flat turnip I don't think of calling 

 a root, any more than I do of calling the clam a fish.* We are 

 not discussing the question of raising five hundred bushels of 

 flat turnips to the acre ; we are discussing the question of raising- 

 root crops. I cannot answer the question from experiment. If
