754 EXPERIMENT STATION RECORD. 



"It will be observed thai the average of is plats in the various sections at Wooster, 

 exclusive of the smith farm, gives in the mechanical analysis 25.23 percent total 

 sand for the soil and 24.1(1 per cent for the subsoil. The total silt in the soil is <>5.43 

 per cent, in the subsoil 64.57 per cent. The clay in the soil is 4.71 per cent, in the 

 subsoil 6.57 percent, The coarse gravel, which may in fact be added to the sand 

 for a final sand-like total, amounted on the average in these plats to 5.84 per cent for 

 the soil and 4.f>2 per cent for the subsoil. 



"The south farm shows in an average of four plats 20.83 per cent total sand in the 

 soil and 21.94 per cent total sand in the subsoil, while the same shows in total silt 

 69.55 per cent for the soil and 66.20 per cent for the subsoil. . . . 



"The per cent of clay in these is 4.26 for the soil and 7.38 for the subsoil, while 

 the coarse gravel is only 1.94 per cent on the average for the soil and 0.66 per cent 

 for the subsoil. It will be noted that the loss on ignition is relatively higher for the 

 south farm when the soil i- considered and less in the subsoil than of the other 

 Wooster soils examined. . . . 



"The insoluble matter and soluble silica in the Wooster soils is quite high, and 

 the actual soluble plant food is contained in a very small percentage of the total soil 

 weight. The percentage of potash in the soil is about 0.25 per cent, being almost 

 the same in soil and subsoil. It will be noted, however, that on the average the 

 south farm plats give 0.10 per cent higher content of potash in the soil than does 

 the remainder of the station farm. The percentage of lime in the Wooster soils is 

 quite low, amounting to less than 0.3 per cent. The percentage of magnesia is 

 somewhat higher than that of lime, amounting to about 0.4 per cent. The percent- 

 age of phosphoric acid, or phosphorus pentoxid, is a little more than 0.12 per cent, 

 being higher in the south farm than in the remainder. The ratio of lime to magnesia 

 in average of all is about 1:1.5. 



"It is proposed to call this soil type of the station farm the Wayne silt loam." 



The total sand in the Columbus soil amounts "to 31.2 per cent in the soil and 30.98 

 in the subsoil, and the total silt 56.51 in the soil and 55.86 in the subsoil, while the 

 percentages of clay are 6.12 per cent in the soil and 7.42 per cent in the subsoil." 



There is almost double the soluble soil constituents in the Columbus soil as com- 

 pared with that found in the Wooster soil. "The percentage of potash is more than 

 double, while the other constituents, such as lime and magnesia, are increased in a 

 slightly smaller proportion. The ratio of lime to magnesia is 1:1.007, showing the 

 close relation of the soil to the limestone in this respect." The phosphoric acid, 

 however, found in the Columbus soils in this series of plats is but little if any greater 

 in quantity than that found in the Wooster soils. 



" Olentangy silt loam is suggested as a name for this soil type." 



"The Strongsville soil contains 22.23 percent total sand, while the subsoil contains 

 only 17.25 per cent. These selfsame soils give 62.24 per cent silt, while the subsoil 

 contains practically the same amount, 61.87 per cent. In clay the soil yields 7.2 per 

 cent clay against 15.6 per cent in the subsoil. The coarse gravel amounts to 3.66 per 

 cent in the soil and less, or 2.98 per cent, in the subsoil. The loss on ignition is 

 very high in these soils, amounting to 6.51 percent, as a result, perhaps, of their 

 having been some years in sod. 



" The chemical analyses give 83.58 per cent insoluble matter and soluble silica in 

 the soil and the same amount, approximately, in the subsoil. Here the insoluble 

 matter and soluble silica is quite a little less than at Wooster, while practically the 

 same in amount as that found at Columbus. The potash found is less than at Woos- 

 ter, 0.205 per cent, and less than half that at Columbus. The lime content is even 

 less than at Wooster, only 0.22 per cent, while that of magnesia amounts to 0.46 per 

 cent, and the ratio of lime to magnesia becomes 1 : 2.09. . . . Notable percentages 

 oi iron oxid and alumina are also found, approximating quite closely to the corre-
