Oswego Strawberries. 139 



200 pounds had been used. This yield, iignred at five cents per 

 quai't, would mean a gain of $32.20. In the same table, the increase 

 from 300 to 900 pounds of muriate of potash was money well 

 invested. The first increase from 300 to 600 pounds, at a cost of 

 $6.20, shows a gain in yield of 792 quarts with a money gain at five 

 cents a quart of §36.90. Again, increasing the amount of potash 

 300 pounds, making 900 pounds per acre at an increase in cost of 

 but $12.50, the gain in fruit is shown to be 1,782 quarts, and the 

 money gain S89.10. 



In Exp. 2 the result of increasing from 500 to 1,000 pounds of 

 dissolved rock, at a cost of not over ten dollars, was a cash gain of 

 $54.65. iS^itrate of soda used alone gave a yield of 800 quarts per 

 acre less than when the same weight of muriate of potash was used 

 with it. 



Exp. 3. These results would tend to show that the soil had a large 

 amount of available potash and was benefited by the application of 

 nitrate of soda. 



Exp. 4 shows a phenomenal yield in both cases, and an almost 

 incredible increase when then the dissolved rock was doubled, at an 

 expenditure of a comparatively small amount of money. Each of 

 these plats was one-tenth of an acre in area — large enough to be of 

 value as to an average — and the yield is well authenticated. 



Exp. 5. This test was on low muck land and will well repay a 

 careful stud v. IS^otice that where nitrate of soda was increased 

 from three to five hundred pounds, the yield did not equal the first, 

 but where muriate of potash was increased from three to five hun- 

 dred pounds (Plats 1 and 5), the yield was raised over one thousand 

 quarts. On Plat 5 there was too much growth of vine ; the berries 

 were soft and not equal in quality and firmness to those on the 

 other plats. 



Exp. 6 show^s no practical difference between the use of potash or 

 phosphoric acid, but it does show that the addition of nitrate of 

 soda was of no benefit. 



Exp. 7. This table shows a fairly well balanced fertilizer, each 

 plat yielding considerable above the average per acre. The muriate 

 of potash, however, shows to better advantage than the sulfate, a 

 result that is to be seen in other tables as well.
