total application at the rate of 100 pounds per acre for Soil 4a and 
200 pounds per acre for Soil 14a, which was somewhat less than the 
rate of the application of the preceding crop. The average of the 
records of the two crops which have thus far been considered are 
presented in Table 7. 
Soil 4 is identical with Soil 4 of the soil mixture tests. See 
page 466. It was made by one part manure by bulk, one part 
sand and two parts clay loam, the percentage by weight being 
15.5 per cent manure, 32.3 per cent sand and 52.2 per cent loam. 
When the soils were mixed, all except No. 12 received acid phos- 
phate, containing about 15 per cent available phosphoric acid, at 
the rate of 600 pounds per acre, and sulphate of potash, contain- 
ing about 50 per cent actual potash, at the rate of 400 pounds 
per acre. Nitrate of soda was applied in solution to Soil 4 at the 
rate of 133 1-3 pounds per acre and double that amount was given 
to Soil 14. These amounts were given in two applications, the 
first being made about a month after the plants were transplanted 
to permanent places and the second about three weeks later.® 
The nitrate of soda contained about 154 per cent of nitrogen. It 
was given in solution to each plant at the rate of 0.491 grams on 
Soil 4 and 0.982 grams on Soil 14. 
The selection and management of the plants and the treatment 
of the plats were alike in all respects and have been described for 
Soil 4. See page 467. 

6 It was intended to apply the nitrate of soda in three applications so as to 
make the total amount at the rate of 200 lbs. per acre for Soil 4, and 400 Ibs. 
per acre for Soil 14, but when the time came for the third application it was 
decided to omit it because the plants had nearly reached marketable con- 
dition.
