ILLINOIS EXPERIMENTS ON FER- 



TIUrZERS FOR FLORICUL- 



TURAL CROPS. 



Bullotln 176 of the Unlvoralty of Illi 

 uols on "Tlio Use of (■ominorolal Ker- 

 tllizvrs In CiruvvliiK (.'itrnatiuiiH" has 

 Just b<-i>n IsHtit'd and iii;i> be obtained 

 by u|iiillcu(lou to Ihi' Agricultural Ex- 

 perliuont Station, rniM-rslty of IIU- 

 nols, Urbiuiu, Illiuols. It contains the 

 results of experiments upon the use of 

 dried blood, aild phos|iliutc, and potas- 

 sium sulfate In carnation growing 

 which have appeared from lime to time 

 in previous reports in llie trade papers. 

 The most important points are, briefly, 

 that dried blood ur ammonium sulfate 

 can be used with benelit on soils nat- 

 urally moderately well supplied with 

 organic matter; that no benelU has so 

 far been found from the use of potas- 

 sium sulfate on a brown silt loam soil; 

 and that an increase in production 

 was noted when acid phosphate was 

 supplied in addition to dried blood, 

 particularly with the variety Enchan- 

 tress, less so with White Perfection. 

 Comi'arative exi>eriments, also, have 

 shown that these commercial fertil- 

 izers may be used in moderation with 

 the assurance of producing a crop as 

 large and of as good a quality as with 

 manure exclusively. 



The carnation experiments during 

 the present as well as last year have 

 been ones on a more extensive scale 

 in regard to the value of acid phos- 

 phate, in this experiment as a supple- 

 ment to sulfate of ammonia. Tlie va- 

 rieties White Perfection and Rosette 

 have been used and with these varie- 

 ties, no increase has been found. This 

 contradiction of the experiment of 

 1912-13 (liul. 176) may be due to the 

 use of sulfate of ammonia in place ot 

 dried blood used that year or to the 

 fact that the varieties used are not re- 

 sponsive to its use as Enchantress is. 

 It looks as if it were necessary in this 

 connection to study closely the differ- 

 ence in response to fertilizers of the 

 variety type represented by Enchan- 

 tress and Beacon, which stool rather 

 profusely and ot the type represented 

 by Rosette and White Perfection. 



Continued experiments in the over- 

 feeding of carnations have shown that 

 the danger from overfeeding with com- 

 mercial fertilizers can be roughly pre- 

 dicted from a knowledge of their solu- 

 bility in water. For instance, sulfate 

 of ammonia (of whicli about 6 pounds 

 dissolve in a gallon of water) Is mark- 

 edly injurious while acid phosphate (of 

 which 1-6 pound dissolves in a gallon 

 of water) shows no, or almost no. in- 

 jury in very heavy applications. The 

 injury from equal applications of po- 

 tassium sulfate, of which 2-3 pound 

 dissolves in a gallon is less than that 

 from ammonium sulphate but is still 

 severe enough if large amounts are 

 used to cause complete ruin of the 

 crop. 



A careful comparison of weather 

 conditions daily with daily production 

 records has given data that clearly 

 establishes the relation between pe- 

 riods of cloudy weather and splitting 

 in carnations. The long period of con- 

 tinued cloudy weather of the fall of 

 1914 (about three weeks) was fol- 

 lowed, for instance, by an increase in 

 the percentage of splits up to as much 

 as 25 per cent. The increased split- 

 ting is not coincident with the period 

 of cloudy weather, however, but fol- 

 lows it by a week or two. The rec- 

 ords showing how these conclusions

Excessively high applications of 

 acid phosphate to first year roses have 

 caused slight injury, more marked 

 with Richmonds than Killarneys. But 

 amounts ui) to 40 pounds i)er 100 

 square feet of bench space, (which is 

 equivalent to 1 pound per cubic foot 

 of soil if a compost is made, or about 

 9 tons per acre) have given a larger 

 number of flowers than the soil to 

 whicli none was applied. The need for 

 acid phosphate, is most marked in the 

 latter part of the season, and the In- 

 crease due to its use is greatest at that 

 time. No benefit from the use of dried 

 blood has been found on the soil at the 

 Experiment Station (a brown silt 

 loam) until the spring of the year after 

 the plants were set in the previous 

 summer. The results seem to show 

 a decrease from its use in fall or win- 

 ter on fresh soil. In the spring, how- 

 ever, the plants show the nitrogen 

 starvation by yellowing of foliage and 

 increased production follows the use of 

 a nitrogenous fertilizer. 



A study is being made in the chemical 

 laboratory of the value of liquid manure 

 made ( 1 ) from fresh droppings, (2) from 

 barnyard manure, and (3) from shred- 

 ded manure. The relative value of 

 steaming and of fermentation in pre- 

 paring it also are being worked out. 

 This is a practical problem, the results 

 of which can be of immediate use to 

 the florist. In connection with this 

 and other work, a study is being made 

 of the variation of temperature and hu- 

 midity in greenhouses and their rela- 

 tion to growth as measured by the 

 growth records of roses. The results 

 obtained on these subjects up to the 

 present are interesting but hardly 

 com|)lete enough for publication. In 

 the latter study, the Experiment Sta- 

 tion has been assisted by several 

 florists and opportunity is taken at 

 this time to acknowledge their kind 

 co-operation in this difficult problem.
