EXPERIMENT STATION RECORD. 



"All of the soil nscd for this work at the home station has hoen rich in lime and 

 very poor in humns. From the work whicli has heeu done here during the last 5 

 years, the results have been quite uniform, and indicate very plainly that for such 

 soils the first work in restoration must be the providing of a liberal 8u])ply of 

 humus, whicli may come from either stable manure, cotton seed, or the plowing 

 nuder of green leguminous crops, and that any additional fertilizers used should 

 he rich in potash, though they need contain but little jihosphoric acid." 



At Holly Si)rings results for the diflerent years do not accord. 



"So far as can be seen from the work done, the upland clay soils of that region 

 •will be fertilized most economically by the use of either [cotton seed] meal or com- 

 post to furnish veg('tal)le matter an<l nitrogen, and to these should be added both 

 phos])horic acid and potash, more of the latter than the former being needed. For the 

 sandy valley lauds cotton-seed meal seems the best foundation for the fertilizer, and 

 to that should be added more phosphoric acid than potash, though both are needed." 



At Lake, in the pine woods region, the average yields of seed cotton 

 per acre on a sandy clay loam containing but little lime were as follows:
