0^2 CITRUS FRUITS AND THEIR CULTURE. 



drained, or the evil effects of a superabundance of water 

 can be avoided, they are very desirable for citrus fruits. 

 It is on these soils that large numbers of citrus trees have 

 been set and good groves established along the Caloosa- 

 hatchee Kiver as well as elsewhere in Florida. 



In addition to these soils, mention should be made 

 of the hickory or the hickory scrub lands, stretching in 

 broken areas along the shores of the Indian River, from 

 about Cape Canaveral northward. They are covered for 

 the most part with a growth of hickory and the soil is a 

 pure yellow sand with a goodly admixture of humus in 

 the surface layer. In some respects they correspond to 

 1he high pine lands of the interior and appear to be well 

 adapted to citrus fruits. The chemical analyses show 

 the following percentage of the important plant foods: 

 .07 per cent nitrogen, .0862 per cent lime, .0431 per cent 

 phosphoric acid and .011 per cent potash. 



Other soils are used for citrus culture in the State, 

 but those described above have generally proved most 

 satisfactory. 



LOUISIANA. 



In Louisiana, the rich, alluvial soils of the Missis- 

 sippi delta are used for citrus trees. These correspond 

 in some degree to the low hammock soils of Florida, but 

 are much richer and contain more humus. Particular 

 attention has to be given to drainage. 



CALIFORNIA. 



The best citrus soils in California are found on the 

 higher levels and among the foothills. In most parts of 

 the State the actual composition of the soil, whether it 

 be red soil, granite or sandy loam, does not matter so
