169 lbs. per acre of actual potash, 72 lbs. of phosphoric acid from the ashes,
as well as 57 lbs. from the acid phosphate, and lime at the rate of 32 lbs. per
tree, or 1,536 lbs. per acre.
The effect of the fertilizer was measured by the yield and color of the fruit.
Although there was a slight annual average increase in yield per tree on the
treated plats for the several varieties, with the exception of Northern Spy,
the results are considered practically negative from a financial standpoint,
since the calculated gain per year on 5 acres is only $24.50, or not more than
enough to pay for handling the fertilizers. It is also noted that both the
treated and untreated plats increased markedly in yield from 1893 to 1904.
By way of explanation it is stated that prior to 1893 the orchard was in sod,
but during the experiment was kept under cultivation and grew more productive.
The results as to the color of fruit appeared to lack uniformity and "were
not decided enough in a sufficient number of the 12 seasons to enable us to state
that the fertilizers applied improved the color of the apples." The influence
on color appeared most marked in seasons with climatic conditions unfavorable
to the development of the fruit.
With regard to the practical application of the results obtained in this
experiment, it is believed that fruit growers should not apply manures in
quantity until good evidence has been obtained as to what food elements, if
any, are wanting in the soil. This should be ascertained by fertilizer tests conducted
directly in the orchard in question. A brief plan adapted from a fertilizer
experiment under way for the past 10 years in a young apple orchard on
the station grounds is given to be used by the grower in determining to a certain
extent what fertilizer his orchard needs.

Fertilizers on prune trees, A. L; KNISELY (Oregon Sta. Rpt. 1905, pp. 5759).-Fertilizer
experiments were conducted on a 5-acre Italian prune orchard
during the 4 years from 1901 to 1904, inclusive. The soil was classed as a
loam and was similar to many other prune orchard soils. Alternate rows
throughout the entire orchard were treated with nitrate of soda, Thomas slag,
muriate of potash, and sulphate of potash, either alone or variously combined.
The results secured in the last 3 years of the experiment are presented in
tabular form, showing the average yield of fresh prunes per tree. No marked
effects from the different combinations of fertilizers were noticed during the
growing season, and the results were not decided enough to indicate a very
profitable use of fertilizers.
Further experiments are to be made in order to ascertain whether the
quality of the fruit has been affected by the fertilizers, in which special attention
will be given to the sugar and acidity in the ripe fruit.
