M.VNCUKS FOR SPEiI.VL ( UOPS. 285 



* As before stated, the laud was of a stronger nature tbaii that 

 o^ wliich the tirst set of experiiDents wac made, and it was evi- 

 dently in better condition, as tlie plot b-viui; no manure procluecd 

 20 busbels of ears of corn per acre more than tbe plot witbout 

 manure in tbe '^tber field. 



" On plot 4, 300 lbs. of superpbospbate of lime gives a total in- 

 crease of 11 busbels of cars of corn per acre over tbe unmanured 

 plot, agreeing exactly witb the increase obtained from tbe same 

 quantity of tbe same manure on plot 5, in tbe first set of experi- 

 ments. 



"Plot 3, dressed witli 150 lbs. of sulphate of ammonia per acre, 

 givts a total increase of 28 busbels of ears of corn per acre, over 

 tbe unmanured plot; and an increase of 22.^ bushels of ears per 

 acre over plot 2, which received 20 loads of good, well-rotted barn- 

 yard-dung per acre. 



" Plot 5, with 400 lbs. of Peruvian guano per acre gives the best 

 crop of this series viz : an increase of 33 busbels of corn per acre 

 over the unmanured plot, and 21 ^ over the plot manured with 

 20 loads of barnyard-dung. The 400 lbs. of ' Cancerine ' — an arti- 

 ficial manure made in New Jersey from fish — gives a total in- 

 crease of 18 busliels of eai-s per acre over tbe unmanured plot, and 

 12A bushels more than that manured witb b;irn-}-ard dang, though 

 5 busbels of ears of sound corn and 10 bushels of 'nubbins' per 

 acre less than tbe same quantity of Peruvian guano." 



MANURES FOR TURNIPS. 



To raise a large crop of turnips, especially of ruta-bagas, there is 

 nothing better than a liberal application of rich, well-rotted faim- 

 yard-manurc, and 250 to 300 lbs. of good superphosphate of lime 

 per acre, drilled in with the seed. 



I have seen capital crops of common turnips grown witb no 

 other manure except 300 lbs. of superphosphate per acre, drilled 

 with tb? seed. Saperphosphate has a wonderful efiFect on tbe de- 

 velopment of the roots of the turnip. And this is the secret of its 

 great value for this crop. It increases the growth of the young 

 plant, developing tbe formation of tlie roots, and when tbe turnip 

 once gets full possession of tbe soil, it appropriates all tbe plant- 

 food it can find. A turnip-crop grown with superphosphate, can 

 get from tbe soil much more nitrogen than a crop of wheat. The 

 turnip-crop, when supplied with superphosphate, is a good "scav- 

 enger." It will gather up and organize into good food tbe refuse 

 plant-food left in tbe soil. It is to tbe surface soil, what clover is 

 to tbe subsoil.
