CHAPTER XVIII 



ROTATIONS TO PRODUCE ANIMAL AND HUMAN FOOD 



We will now proceed to discuss the second type of 

 rotations, where the object aimed at is the production 

 of animal along with a certain portion of human food. 

 A typical rotation of this nature is as follows: — 



1st Year. — Potatoes on the lea. 



2nd Year. — Autumn sown rye after potatoes fol- 

 lowed by " winter greens." 



3rd Year. — Spring sown cereals. 



4th Year. — Autumn sown tares with seeds, the 

 latter sown in spring. 



5th Year. — Seeds grazed in previous autumn, cut for 

 hay and aftermath grazed again. 



This rotation also provides for an even distribution 

 of labour throughout the year. 



As regards the growing of potatoes on the lea, any- 

 one familiar with potato growing is well aware that 

 lea potatoes can always be depended upon to give a 

 magnificent crop of tubers of the finest quality. Until 

 quite recently, however, considerable difficulty was 

 experienced in tilling lea land for potatoes. The intro- 

 duction of the disc harrow though, has solved this 

 difficulty. It is as easy to till even very old lea for 

 a drill crop with a good implement of this kind, as 

 to till stubble land without it. 



The lea land, before ploughing, should be disc 

 harrowed in opposite directions so as to cut the turf
