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 chart shows the final cropping plans 

 and fertilizer treatments for this farm. 



Rotation Chart for Problem II 



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 winter cover crop, such as winter grain, crimson 

 clover and bur clover, plowed under. 



2 Cowpeas, planted in May and harvested in August. 



3 Oats or wheat. (Followed by cowpeas, plowed under). 



4 Corn (The corn may be interplanted with cowpeas, soybeans or 

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

 crop for next year's cotton.
