ROTATIONS TO PRODUCE FOOD 209 



Another rotation of the type under discussion, in 

 which a greater proportion of corn is raised than in 

 the foregoing, is as follows: — 



1st Year. — Corn inter-cropped with " winter 



greens." 

 2nd Year. — Potatoes. 

 3rd Year. — Corn inter-cropped or followed with 



autumn sown tares. 

 4th Year. — Tares, either hayed or ensiled, and 



" winter greens." 

 5th Year. — Spring corn and seeds. 

 6th Year. — Seeds hay, aftermath ensiled or hayed. 

 7th Year. — Seeds grazed. 



REDUCING THE RISKS 



The outstanding features of this rotation are that 

 whilst a considerable area is given to corn production, 

 the cultivation of three corn crops are carried out at 

 three different times in the year. Again, the harvest- 

 ing of the corn crop will take place at three different 

 times of the year, which not only means a more equit- 

 able distribution of labour but a diminution of harvest 

 risks. 



This latter feature can best be described in the 

 words of an Irish farming friend. He had adopted the 

 system, and spoke of having his corn harvest " divided 

 into three halves " I ! 



As distinct from the production of corn on the ordi- 

 nary lines, the humus and vegetable contents of the 

 soil are maintained by the growing of such a large 

 amount of winter greens and tares, which can either 

 be ploughed in for green manure or, in the writer's 

 opinion, more economically used by grazing first with 

 sheep, and the resultant residue then turned under.
