PARTICULAR DATA CONCERNING HACIENDA 

 CARTAVIO. 



Cartavio is a long and narrow estate; not including its recently 

 ncquired properties, it is about 10 miles long and 2 miles wide at 

 the widest part narrowing down to a mile or less. 



There is a marked variation in the soils, even between those of 

 adjacent Sections as will be seen by examining the analyses of soils 

 and locating the Sections on the map. There is also a noticeable 

 difference in the amounts of the most important soil elements. To 

 .show this at a glance, the percentages of potash, phosphoric acid, lime 

 and nitrogen, are here given from Sections taken in a line lengthwise 

 of the estate. 



Another interesting feature of these soils is the variation in their 

 physical condition; some are loose and sandy while others are stiff. 

 The improvement of the physical condition of some of them is quite 

 as important as supplying potash, phosphoric acid and nitrogen. Sec- 

 tion 10 has a soil whose physical condition is good but is not partic- 

 ularly rich in plant food elements; Section 4, on the other hand, 

 has a stiff, cracky soil that is difficult to work, but its chemical anal- 

 ysis shows it to be high in total plant food elements. Section 10 

 gave 7 cuts of cane, the last cut yielding 43.04 tons of cane per acre; 

 Section 4 allowed of but 4 cuts, the last giving only 16.62 tons per 

 acre. Section 4 has the richer soil but it needs physical rectification; 

 the addition of large quantities of sand would doubtless increase its 

 productiveness. 



Although some of the soils have been under cultivation fora num- 

 ber of years, their production of cane is increasing, and with con- 

 tinued proper treatment they will improve for a good many years to 

 come. 



The yield of cane for the past three years has been between 45 and
