182 FARM AND SCHOOL PROBLEMS. 



PROBLEMS IN PLANNING ROTATIONS. 



In the following problems, the solution should be accom- 

 panied with diagrams showing shape and size of farms and 

 fields, location of farmstead with arrangement of buildings, gar- 

 dens, orchards and windbrakes. In some of these problems, 

 where a farm in the neighborhood is used as a concrete example, 

 there may be included with the plans for rotation a map showing 

 topography, drainage, soil types and soil ingredients. 



PROBLEMS. 



1. Plan a good rotation for a farm of 80 acres for the production 

 of corn, oats, wheat and clover. 



2. Plan a rotation for a 120 acre farm for raising alfalfa and lambs. 



3. Plan a rotation for a 160 acre farm for raising corn and swine. 



4. Plan a rotation for a 60 acre dairy farm having a 12-cow dairy. 



5. Plan a 100 acre tract for grain production. 



6. Plan a 40 acre poultry farm for keeping 1000 hens. 



7. Plan a rotation for a 200 acre general purpose farm. 



8. Plan a rotation for an 80 acre farm that will include 20 acres of 

 sugar beets. 



9. Plan a 100 acre farm for a southern plantation that raises 20 

 acres of cotton. 



10. Plan a 40 acre farm to be devoted to fruit, poultry and dairying. 



11. Plan a farm of 10 acres for fruit within 10 miles of your near- 

 est city. 



12. What is the difference between specialization and diversification 

 in farming? 



13. Arrange a crop rotation for Ohio; a crop rotation for Georgia; 

 a crop rotation for Iowa; a crop rotation for California; a crop rotation 

 for North Dakota. 



14. A field has been in corn ten years continuously and the average 

 production for the ten year period has been 25 bushels per acre; if a rota- 

 tion ofi corn, oats and clover had been followed yielding 4 crops of corn 

 of 50 bu. each per acre, 3 crops of oats of 50 bu. per acre, 3 crops of clover 

 each of 2 tons per acre, what would have been the gain of this rotation 

 instead of continuous cropping of corn for 10 years, based on cost of pro- 

 duction per acre for corn $13, oats $10, clover $4, at present prices ? 



Demonstrations and Experiments in Rotation. 



On the Wooster plats where there has been continuous 

 cropping of corn for about 20 years it has been demonstrated that
