11. What would be the net return on 30 acres on 

 a crop of 24 bushels of wheat per acre, after paying 

 all the above expenses and selling the wheat at 90 

 cents per bushel and paying $5 per acre relit? 



Comparison of Different Crops Rotation of 

 Crops 



1. Suppose a 40-acre field planted to corn for 5 

 years in succession produces 60 bushels per acre the 

 first year, 55 the second, 43 the third, 33 the fourth, 

 and 30 the fifth, what will be the value of the corn 

 grown in the 5 years, at 40 cents per bushel? 



2. Suppose instead of growing corn continuously 

 he had practiced the following rotation : 



First year 40 acres corn, 60 bushels per acre, at 

 40 cents. Second year 40 acres oats, 60 bushels per 

 acre, at 30 cents. Third year 40 acres clover, 3 tons 

 per acre, at $8 per ton. Fourth year 40 acres tim- 

 othy, 2 tons per acre, at $9 per ton. Fifth year 40 

 acres corn, 70 bushels per acre, at 40 cents per bushel. 



What would have been the value of the five years' 

 crop? 



3. Which of the two plans would produce the most 

 money in the five years? How much more? Which 

 would leave the land in the best condition at the end 

 of five years? Are there any other advantages to 

 either plan ? 



4. The average good stand of corn is about 12,000
