EXPERIMENT ON MANURING CHERRY TREES.

Foi the purpose of demonstrating 1 that juifueious manuring is beneficial in the cultivation of the cherry the following results of an experiment carried out by Air R. E. Warren, oi Harcourt, Vie, anda-r the direction of the offices of the Potash Syndicate, Sydney, from w.hich this leaflet is issued, will be of interest, and it is hopad instructiv to all who wish to increase the profits from cherry-growing. No unusual conditions were observed in the experiments beyond the application of the manure? to the different plots, which were carefully selected sr that all should b>» as uniform a» possible, and the same amount of caia and attention v.-iis bestowed on each plot. No. 1 plot received no manure ; No. 2 plot received 21b superphosphate an«-l Jib sulphate of ammonia per tree ; No 3 plot racaived "lb sulphate of potash and gib sulphate cf ammonia per trae; Xo. 4 plot received 2!b superphosphate, gib sulphate of ammonia, and lib of potash per tree. Tlw results showed that while- No. 1 plot yield-ed 30951b per acre, No. 2 plot yielded 621C1b, the value of the increase after deducting cos" of manure being £24 11-*. No. 3 plot y iekle-d 93151b, the- increa->r<l profit being £50 2s 6d. No. 4 plot yielded 18.6301b. or an increased profit over No. 1 plot of £127 3s. The effect of potash according <x> this experiment was most marked. The plot No. 4, with th-e complete manure with potash, gave an increased yield of the value of £127 over the unmanured plot, while plot 2, without potash, gave a yield showing an increase of £24 lls. The time to apply artificial fertilisers to frui* trees is in the winter or beginning of spring; they should be harrowed in, soy not closer than 4ft

from the trunk of the tiree, according to its age. ,
