The following analyses of sugar soils collected from various sources are quoted 

 from Deer, "Sugar and the Sugar Cane." 



LOUISIA::fA SOILS." 



" Quoted originally by Stubbs in "Sugar Cane." 



Stubbs concludes that the average composition of Louisiana soils is lime, 0.5 

 per cent; potash, 0.4 per cent; phosphoric acid, 0.1 per cent; nitrogen, 0.1 per 

 cent. 



JAVA SOILS." 



» By Kramers, and quoted by Kruger in "Das Zuckerrohr." 



These soils are considered decidedly poor in every constituent except lime, and 

 yet Java is producing from them, by scientific methods of cultivation, over 10 

 metric tons of sugar per hectare per annum, over three and one-half times the 

 present yield in Negros. 



DEilERABA SOILS." 



The first had been in cultivation for five and the second for over sixty years. 

 The third is a Queensland soil quoted from the same source.
