FARM MANAGEMENT AND CROP ROTATION 



Because of the twelve acres of alfalfa the farm must necessarily 

 be divided into six units of twelve and thirteen acres each. 



The following rotation chait shows the final croppmg plans 

 and fertilizer treatments for this faim.

Problem III. — ^Plan a system of cropping on an eighty-acre 

 grain farm in Arkansas, on which are to be grown cotton, corn, 

 cowpeas and oats as the main crops. Sufficient pasture is to be 

 provided for the horses and mules and for a few head of cattle. 

 As many hogs are to be kept as conditions well permit. 



Soil problems to be met are, drainage and deficiency of organic 

 matter and phosphorus. 



Figure 219 illustrates the conditions before reorganization. 



Figure 220 shows how the farm was remapped. The drainage 

 problem was easily solved by tiling. 



The following four-year rotation was adopted* 



1 — Cotton followed by a wmtei cover crop, such as winter gram, crimson 



clover and bur clover, plowed under 



2 — Cowpeas, planted m May and harvested m August 



3 — Oats or wheat (Followed by covsrpeas, plowed under) ^ 



4 — Corn (The com may be mterplanted with cowpeas, soybeans or 



velvet beans, which will furnish hog feed and also serve as a green manurmg 



crop for next yearns cotton
