cowpe^is. At Town Civck, where pods did not mature, 

 the vinc^ made tlie best j!:rowth wliere acid pliosphate 

 was appliiMl ; no dillVronce eonhl he det(M*t(»d l)etween the 

 fjrowtli of tlie unfertilize<l plot and that on tlie plot wliere 

 Florida soft phos])hate was employed. 



On the siindy soil near Notasulga ''the plot fertilized 

 with acid phosphate seemed to me one-third better" than 

 the one witli the raw plios])lnite. These observations 

 as to th(^ suiKM'iority of acid phosphate aij^ree with the 

 results of experiments made at the Geor<»ia Experiment 

 Station and with a test made at Auburn in 1898, the 

 results in our (test being as follows: 



Bus. seed 

 per acre. 



Cowpeas, with no phosphate 9.4 



Cowpeas, with 240 lbs. Florida soft phosphate 13.9 



Cowpeas, with 240 lbs. acid phosphate 15.2 



Apparently the raw or Florida soft phosphate was 

 beneficial, and the acid phosphate still more so, the 

 increase with the latter being 5.8 bushels of seed per 

 acre, which gives a fair profit after deducting the cost 

 of the 240 p.'uinds of acid phosphate used on an acre. 



Fcrtilizinf/ cotcpca.s hettrcen corn roiv-s. — In 1900 

 on one plot only half of the acid phosphate was ap- 

 plied to corn, the remainder (120 pounds per acre) be- 

 ing reserved and drilled with Whip]X)orwill cowpeas 

 July 7. There was practically a failure of both the 

 corn and cowpeas on this series of plots, so that the 

 products of the several ploits were not harvested sepa- 

 rately. However, so far as could be judged by the eye, 

 there was never any difference in the growth of the 

 vines directly fertilized with phosphate and those which 

 must have drawn some of their phosphate from the fer- 

 tilizer ithat was applied to the corn some months be- 

 fore.
