FAKM MANAGEMENT OX IRRIGATED FARMS 53 
gated farms of the valley must have water when the tubers begin to 
form, even at expense of the other crops. It is therefore necessary 
to apportion and distribute the resources in advance, in order to 
avoid, as much as possible, the difficulties encountered from com- 
petition between enterprises. 
When one farm enterprise contributes toward the success of 
another, the enterprises are said to have a complementary relation- 
ship. Livestock and crops are complementary, because one fur- 
nishes food for stock while the other provides fertility for the soil. 
Supplementary enterprises are introduced into the farm organi- 
zation to'make the best possible use of resources which would other- 
wise be idle or wasted. Such resources, whether they be in the form 
of labor, land, water, or equipment, are worth to the farmer just 
what he can get out of them. Rutabagas might be used as a supple- 
mentary enterprise in midsummer to take the place of some crop 
which has failed, or they might follow an early-harvested crop, or 
might be grown to use up surplus labor and equipment which hap- 
pens to be available at this time. Different classes of livestock are 
often introduced as supplementary enterprises. Such enterprises 
sometimes compete for the farmer's time, as, for instance, dairying 
and crop work during the summer months, but their value to the 
organization is often of sufficient importance to compensate for such 
competition as is unavoidable. Adjustments can often be made be- 
tween the dairy and crop enterprises by arranging to have more of 
the cows come fresh in the fall. 
NONMARKETABLE RESOURCES MUST BE USED WHEN AND WHERE THEY ARE 
AVAILABLE 
On many farms in every community are found nonmarketable re- 
sources which are worth to the farmer just what he can get out of 
them when and where they occur. The importance of these re- 
sources is often neglected. The use which the operator makes of 
them might easily mean the difference between profit and loss on an 
individual farm. 
In such an area as this, where the farm organization consists 
mostly of crop enterprises, very little productive employment is 
provided for the operator and his family during a part of the year. 
Moreover, unmarketable feeds, such as cull potatoes, rutabagas, 
squash, straw, and beet tops are commonly found on many Yakima 
County farms. Such livestock as dairy cows, hogs, sheep, poultry, 
and turkeys are profitable enterprises for using these unmarketable 
feeds and this unused time. It has often happened in this area that 
the market price of potatoes, rutabagas, and particularly alfalfa hay. 
has been so unfavorable that considerable savings would have been 
possible had more of the crop been marketed through livestock. 
Even though the farmer often must be satisfied with relatively small 
returns for the use of these unmarketable resources, his total net 
income has been increased and his farm business becomes more 
efficient. 
STATEMENT OF PRINCIPLE OF CHOICE 
The whole problem of choosing and adjusting enterprises to meet 
conditions on individual farms might be summarized as follows: 
The procedure to follow in choosing and apportioning farm enter- 
prises on a particular farm is to select as the major lines of produc-
