portion of culls. For growing this crop to best advantage, Food for 

 the soil should either be well manured or a commercial ferti- _ 

 lizer, rich in all of the constituents, should be applied at the 57 

 rate of 400 to 600 pounds per acre, previous to planting; 

 and after the plants have well started, 100 pounds per acre 

 of Nitrate of Soda should be applied; this to be followed with 

 two further dressings of the same amount. The time between 

 the dressings may range from two to three weeks, according 

 to season. 



Celery is a crop that responds most 

 profitably to an application of an abundance 

 of available Nitrogen. This fertilizer aot only increases the 

 yield, but very materially improves the quality of the crop. 

 Where the soil is naturally rich, or where what may be 

 regarded as good methods of practice, in reference to ferti- 

 lizers, are followed, extra applications of Nitrate result in 

 very largely increased yields and proportionate improve- 

 ment in quality. In the experiments that were conducted, 

 it was shown that where ordinary treatment was given, and a 

 small and unprofitable crop was obtained, the addition of 

 a few dollars' worth of Nitrate changed the crop into a 

 very profitable one ; and in the case of a soil that was regarded 

 as good enough to produce a fair crop, the addition caused 

 a large increase in total crop, and a very marked improve- 

 ment in the quality. The selling price of roots grown with 

 Nitrate was 150 per cent, greater than where none was 

 applied, and 100 per cent, greater than where an insufficient 

 amount was used. The increased value per acre of the crop 

 from the best use of the Nitrate was over $250. 



The celery crop is expensive, both in 



plants and in labor, and since the cost of Methods of 

 these items is the same whether the crop is Application, 

 large or small, intensive systems of feeding the crop usually 

 give excellent returns. The crop is also very much improved 

 in quality if the conditions are made favorable for continuous 

 and rapid growth, hence an abundance of moisture and of 

 immediately available food are prime essentials. The former 

 can be controlled to a large extent by good methods of 

 culture, but the best culture of the best soils is not capable 

 of providing the necessary food, and, of the essential elements 

 of food, Nitrogen seems to be the one that contributes espe-
