Celery is a crop that responds most pS2?ts r 



profitably to an application of an abun- 

 dance of available Nitrogen. This fertilizer not only 59 

 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 fertilizers, are followed, extra 

 applications of Nitrate result in very largely increased 

 yields and proportionate improvement 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 re- 

 garded as good enough to produce a fair crop, the addi- 

 tion caused a large increase in total crop, and a very 

 marked improvement 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 in- 

 creased value per acre of the crop from the best use of 

 the Nitrate was over $250.

ol these items is the same whether the 



crop is 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 con- 

 trolled 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 especially to rapidity of growth and to the 

 formation of stalk which possesses that peculiar crisp- 

 ness which in so marked a degree measures marketable 

 quality. Soils that are deep, moist and rich in organic 

 matter are best suited for the crop; these should be 

 heavily manured, say, at the rate of ten to fifteen tons 

 per acre, and should also receive liberal amounts of
