The plain superphosphate contains about sixteen or eighteen per cent, of phosphoric acid, and 400 to 600 pounds per acre is a liberal and very useful dressing for bearing orchards. The bone fertilizers are always valuable. Those which are untreated give up their phosphoric acid slowdy, unless they are very finely ground. Dissolved bone gives more immediate results. Thomas or basic slag has given good results in many tests, but it parts with its fertility very slowly. Phos- phoric acid is rather less important in fruit plantations than potash, although this order is reversed in general 2 1 A little lesson in fertility: The size of these blocks shows the comparative quantities of soil fertility (nitrogen, potash, and phosphoric acid) removed from the farm by the selling of various home-grown prod- ucts. The growing of wheat or beef draws heaviest on the soil ; butter or fruits, lightest. Remem- ber, too, that most of the fertility removed by fruits is contained in the seeds or the pit, — the.
