a Special Plots. 



Table III, which shows the increase in 

 24's and decrease in 42's, as the fertilizer 

 is increased, still further emphasizes this 

 fact. For example, by reference to the 

 table it will be seen that the total num- 

 ber of 24's in the third plots of the upper 

 sections is 277, while the total number 

 in the fourth plots, which received one- 

 fifth more fertilizer than the third, is 

 exactly the same — 277 In the lower half, 

 the total 24's in the third plots of the 

 sections is 262, while in the fourth it is 

 269 — only 7 more. A further study of 

 this table will reveal the rapid increase 

 of 24's from the first to the third plots of 

 nearly all the sections, but as already 

 pointed out this increase does not extend 

 to the fourth plots in very many cases, 

 while in some instances there is actually 

 a decrease. On the other hand there is 

 a decrease in 42's which is very decided 

 from the first to the second plots of the 

 sections but more gradual from the 

 second to the fourth. 



Assuming that the total number of 

 pines on the third horizontal line of 

 plots would have been the same as the 

 total number on the first line, had the 

 fertilizer not been increased on the third, 

 we have a basis for calculating the 

 increase in crop value due apparently 

 to the quantity of fertilizer which was 

 added to the third line of plots above 

 that which was added to the first. By 

 referring to the first column headed 

 total in Table III., and taking the sum 

 of the total number of 24's from the third 

 line of plots, both upper and lower sec- 

 tions, it will be found to be 530, while 

 the total from the first line of plots, 

 both upper and lower sections is 169, 

 giving an increase on the 22* plots appa- 

 rently due to increase in fertilizer, of 370 

 pines or about 15| crates. Since these 

 plots are 1-150 of an acre the increase is 

 at the rate of 105 3-5 crates per acre, 

 which, at $l'65t per crate would amount 

 to $174 "24. Again, referring to the same 



* Sections V. and W. being intended for special 

 purposes have been omitted from this count. 



t An experienced grower estimates that taking 

 a series of years 18's would bring $l - 80, 24's and 

 30's $1-65, 36's $1-30, and 42's $1-10 per crate. 



table it will be seen that the 42's have 

 decreased from a total of 386 in the first 

 line of plots to 114 in the third line, 

 making a loss of 272 pines or 6J crates for 

 the 22 plots, which is at the rate of 44 1-3 

 crates per acre, which at $1'10 would be 

 worth $48'67. Subtracting this from 

 $174-24 we have $125 '47 gain, due appa- 

 rently to increasing the number of 24's 

 by increasing the fertilizer about 3-4 of 

 a ton per acre. To get the net gain we 

 have but to deduct from this the cost 

 of the extra fertilizer. Calculating the 

 cost of the extra fertilizer added to the 

 third line of plots, above what was 

 added to the first, on the basis of the 

 cost of the raw materials at the factory, 

 we find it to be $3'88 for the 22 plots, 

 which is at the rate of $26"45 per acre. 

 Deducting this from $125'47 leaves us a 

 gain of $99*02. Prom this must still be 

 deducted the cost of mixing and the 

 freight rate from Jacksonville to the 

 pineapple district, and this would be, 

 according to statement furnished by a 

 manufacturer, $3 - 79 per ton ; and since 

 the extra fertilizer required amounts to 

 about 3-4 of a ton, this change would be 

 $2*85. Deducting this from $99 02 would 

 leave us a net profit per acre on the 24's 

 of $96 , 17." In the same way it may be 

 shown that the increase in value of the 

 30's above the decrease of 36's is about 

 $11'80, and this is net gain, the fertilizers 

 having already been accounted tor. 

 This makes the total net gain $107'97. 

 The gain in 18's was so slight that they 

 were not taken into consideration in 

 this case. But this does not represent 

 the entire possible gain, since in an 

 experiment some fertilizers are used in 

 order that their unfitness for the parti- 

 cular crop may be demonstrated, and 

 the results from such plots are neces- 

 sarily lower than they would be under 

 ordinary circumstances. This can be 

 demonstrated by calculating the increase 

 in value on one of the best plots. On 

 examination we find that plot 19 of 



* In making these calculations we havs 

 made them for the average year and not for 

 the first crop, which would require a little more 

 extra fertiizer than the 1 ton provided for.
