Top-Dressing 



At a Profit 



And at a Loss 



In a Top-Dressing experiment that was con- 

 ducted over a period of nine years the Station 

 proved that a farmer could get a profit of $1.75 

 per acre by applying 200 lbs. of nitrate of soda 

 to timothy and clover grassland. If this infor- 

 mation were utiUzed on all of the New Hamp- 

 shire land in these grasses, it would make a 

 difference of $367,000 in the annual hay crop. 

 Applications over a shorter period showed a 

 net profit of $12.16 per acre in Grafton County, 

 and the increased hay cost only $4.86 a ton. 

 These figures of course fluctuate with the prices 

 of nitrate and of hay.

 when no fer- 

 tilizer is used. 



On the other hand, it was proved that New 

 Hampshire soils, particularly if of a heavy 

 type, do not need potash for hay. Instead 

 of using the prevalent 5-8-4 fertihzer, the far- 

 mer could save $2 an acre by using fertilizer 

 without the potash.
