fids. S; Hill. 116, Ahs. (I'Jl.'i). pii. .J).^Tbt' oxiierinients here reported in detnil 

 were conducted to deterniine the feasibility of the complete or partial siibsti- 

 tiitiou of commercial tertilizt>rs for nianuro as a source of plant food for carna- 

 tions. 



In the first oxperiment, exlendinj; over a period of three years, commercial 

 fertilizers in various proportions and amounts \A-ere applied to different sections 

 of benches in the greenhouse an<l the effects on the number and quality of the 

 flowers noted. In the second experiment, extending over two years, the pro- 

 duction of sections treated with manure was compared with that from sections 

 treated with commercial fertilizers. A uniform soil was selected for all 

 .sections. 



The results of the work as a whole lead to the conclusion that dried blood 

 (or ammonium sulphate instead), acid phosphate, and i)Otassium sulphate may 

 safely be used in the culture of carnations. On the brown silt loam used in 

 the experiments nitrogenous fertilizers have produced a consistent increase in 

 production. Nitrogen may be regarded as the limiting element of growth. 

 There are indications that the addition of acid phosi>hate to a nitrogenous 

 fertilizer will cause a still further increase in production and an imjirovement 

 in quality as well. The quality of flowers produced with commercial fertilizers 

 as measured by various factors is equal to that of those grown with manure. 

 The time of maximum crop production was indei>endent of the liind of fer- 

 tilizer used and its time of application. Injury from overfeeding results from 

 the excessive use of potassium sulphate and dried blood. On the other hand, 

 large quantities of acid phosphate seem to improve the quantity and quality of 

 the flowers.
