Damp and heavy soils areunfavorable. The plant is a gross feeder and calls for a liberal supply ofnitrogenous fertilizers. Experiments carried on in Porto Rico have demon-strated that the plant responds to commercial fertilizers. A small plant,although in poor soil, has attained astonishing proportions after the fertil-izer has been applied. So, when enough plant-food is available and theroots may obtain all the air they need, the pineapple can be successfullygrown on a wide range of soils. *In preparing this chapter the author was assisted by Mr. F.

MISCELLANEOUS TROPICAL FRUITS 101 From one to two thousand pounds per acre of blood and bone or cotton-seed meal will improve the size and quality of the fruit, and maintain thefertihty of the land. The following summary taken from Bulletin 104 ofthe Florida Experiment Station, will serve as the best guide for the fertil-izing of pineapples. (a) Fine-ground steamed bone and slag phosphate are best as sourcesof phosphoric acid; cottonseed meal, dried blood and castor pomace arebest as sources of nitrogen; high-grade and low-grade sulphate of potashare best as sources of potash. (6) Nitrate of soda, acid phosphate and kainit have not proven satis-factory. (While sulphate of ammonia was not used in the
