FARM MAiSTAGEMENT IK LENAWEE COUKTY, MICH. 23 



The 300 farms are divided into two groups on the basis of crop 

 yields and into four groups on the basis of the receipts per animal 

 imit. The first division on the crop basis includes all farms which 

 have a crop index ratmg below 100, i. e., the farms that are making 

 yields below the average of all the farms studied for that year; the 

 second division includes all farms with a crop index rating above 100. 

 The farms makmg $40 and less per animal unit and with crop yields 

 below the average, lacked $100 per farm (mmus $100 labor income) 

 of paying all expenses and 5 per cent interest upon investment, while 

 those of the same quality of live stock but with crop yields above the 

 average made an average labor income of $192. Thus the difference 

 in crop yields in the groups making $40 and less per animal unit, 

 made a difference of $292 in the average labor income for each farm. 

 In the next group of farms, those making from $41 to $60 per animal 

 unit, the difference in the average labor income per farm was $297, in 

 favor of those with good crops. The average size of the farms is 

 greater m the latter case, (120 as compared with 96 acres.) This was 

 due to the fact that the largest farm of the survey, one of 675 acres, fell 

 in this class. With this farm omitted, the figures shown in the table 

 in parentheses would have been the result ; the average size would 

 have been but 108 acres and the average labor income only slightly 

 less, or $509. In the group of farms making from $61 to $80 per ani- 

 mal unit, the average acreage is practically the same and the average 

 labor income of the farms with crop yields below the average is $482, 

 as compared with $718 for those with crop yields above the average. 

 With the average acreage about the same in the group receiving over 

 $80 per animal miit, there is a difference in average labor income of 

 $288 in favor of those farms having the better crop yields. Taking 

 all farms, with an average difference of but 12 acres and 5 animal 

 units per farm, there is average difference of $378 in labor income in 

 favor of the farms with crop yields above the average. 



The influence of good live stock on the average labor income of the 

 300 owner-farms studied may be seen first in the farms havmg poor 

 crop yields, (less than 100 crop index) or which were. below average of 

 the area in crop yield, and those that were above the average in crop 

 yield for that year (above 100 crop index). When the receipts 

 increase from $40 and under per anunal unit to over $80 per animal 

 unit there is a gradual increase in the average labor income from 

 minus $100 to plus $829 in the farms below the average in yield; 

 while in the farms with crop yields better than the average' there is an 

 increase in the average income per farm from $192 to $1,117. Fur- 

 ther study of the data presented shows that the size of farm and 

 several irnportant factors other than the two on which this tabulation 

 is based, are practically the same for the different groups; hence it 

 seems fair to conclude that quality as expressed in crop yield and
