most of the sugar beets were grown on the former. In the Oxnard 
district there are two soil types, Oxnard sandy loam and Oxnard 
sand. As is suggested by the name, the Oxnard sand is the coarser 
and more open of the two and contains less organic matter. The 
sandy loam is probably better adapted to sugar-beet production than 
is the sand: In the Salinas district the records were obtained on 
three types of soil, Salinas gray adobe, San Joaquin black adobe 
and Fresno fine sandy loam. Salinas gray adobe is very sticky 
when wet, becoming hard when dry. It holds moisture well. At 
certain seasons of the year it is very heavy to work. San Joaquin 
Wig. 4.—A field which has received an application of waste water from the beet-sugar 
factory. This water contains considerable lime, which is deposited on the surface 
of the field. The whitened portions of the ground indicate that the surplus water 
flowed into these areas and the lime was left after the water had passed into 
the soil. 
black adobe is similar to Salinas gray adobe, and is probably a little 
better adapted to sugar-beet production. Sugar beets are grown also 
on Fresno fine sandy loam, but they probably do best on the adobe 
soils. 
SIZE OF FARMS. 
The relation of the sugar-beet enterprise to size of farm may be 
seen in part by comparing the Thirteenth Census figures with the dis- 
tribution of the records obtained in this investigation (see Table V).
