MANURES AND FERTILIZERS. 69 
sod land is plowed after the green growth has 
got well started. Those persons who have 
grown a crop of corn on land in clover or ΄ 
timothy the previous season have noted the in- 
creased yields from it, if the weather conditions 
were satisfactory and the tillage good. 
The manurial value of feeding stuffs, as 
indicated by the amount of nitrogen, phosphoric 
acid and potash present, is shown in the follow- 
ing table, abstracted from a more complete 
table published by Dr. E. H. Jenkins, chemist 
of the Connecticut agricultural experiment 
station.* The nitrogen is estimated at 17 cents, 
the phosphoric acid 6 cents and the potash at 
4. cents per pound. The prices for these sub- 
stances, however, varies from time to time 
according to market supply and demand: 
AVERAGE NUMBER POUNDS NITROGEN, PHOSPHORIC ACID 
AND POTASH IN ONE TON AMERICAN FEEDING STUFFS, 
AND VALUE PER TON FOR MANURE OF SUCH FOODS.
