The commercial fertilizers were used on the clay loam without 

 manure, Soil 7; with manure, Soil 10; and with manure and sand, 

 Soil 1.1. The manure was used with the clay loam, hut without 

 commercial fertilizers in the case of Soil 16, and with the clay 

 loam and sand but without commercial fertilizers in the case of 

 Soil 17. 



The commercial fertilizers were used on the sandy loam without 

 manure, Soil 8, and with manure, Soil 9. The manure was used 

 with the sandy loam but without commercial fertilizers in the case 

 of SoH 15. 



The selection and planting of the seeds and the selection and 

 management of the plants were the same for all the soils as for 

 Soils 7 to 11 an account of which may be found on pages 475 and 

 476. The manner of preparing these soils and the character of 

 their ingredients are given on pages 472-474. The acid phos- 

 phate and sulphate of potash were applied when the soils were 

 mixed. The nitrate of soda was first applied in solution around 

 each plant at the rate of 33 1-3 pounds per acre about 5 weeks 

 after the seed was planted. Similar applications were made each 

 week for 11 weeks, making the total nitrate of. soda which was 

 used amount to 366 pounds per acre. After the plants had grown 

 sufficiently to cover the' ground the nitrate of soda was no longer 

 applied to each plant, but the required amount for each plat was 

 supplied through the tiles which were used for subwatering.
