GREAT CROPS OF STRAWBERRIES AND HOW TO GROW THEM 
Copyright 1915 by R. M. Kelloag Co., Three Rivers, Mich. 
A SCENE ON R. M. KELLOGG COMPANY'S FARM AT TWIN FALLS, IDAHO 
certainly made a wise choice when we selected Twin Falls, Idaho, for our Western farm. There we have ideal soil and 
'^'"nat": conditions and abundance o; water for irrigation. This combination insures the most perfectly developed plants 
that man and nature can produce. Our Idaho grown plants are large, hardy, vigorous and exceedinKly prXctWe and will 
please the most exacting grower We are proud of our Idaho grown plants and we are confident thaLur Western customs" 
will be more than pleased with the plants we ship them this season. The two men in the field are Frank E filatw PreSt 
of our Company and Clyde E. Beatty, Manager of our Idaho farm. Both of these men are strawberrrexpfr^fand thiv sr^ 
that our plants this year are perfect. The plants shown in this field are so large and vigorous that they speak for themselves 
before buds are open will give the plants a 
splendid start into activity. The dried blood 
should be applied after plowing and thoroughly 
worked into the soil before plants are set. 
We prefer to get our nitrogen either through 
manure or legumes. A lack of nitrogen in the 
soil is easily detected. The foliage is small and 
the growth slow. The leaves are smaller and of 
a lighter green than when plenty of nitrogen is 
available. 
Potassium (potash) builds the fibrous matter 
or woody parts in the plants and forms the starch 
and sugar for the fruit. It gives strength and 
endurance and adds hardiness to the plants and 
fHIS is a view of the strawberry plot of E. D. W. Seitz of 
* Michigan. Mr. Seitz in 1914 purchased 55 ) Kellogg straw- 
berry plants composed of Senator Dunlap and Warfield. He 
eays in a letter written September 15, 1915: "Last spring 
these plants yielded 615 quarts of berries. These plants were 
grown in the hill system, and it is by far the best system." 
gives color, firmness and flavor to the fruit, which 
can be secured through no other source. 
Two hundred pounds of sulfate of potash per 
acre, evenly scattered over the plowed ground 
and thoroughly worked into the soil before plants 
are set, will furnish sufficient potassium for one 
crop and will add to the second crop. One ton of 
unleached hardwood ashes will furnish sufficient 
potassium for one acre. 
Phosphorus aids the plants to assimilate other 
plant foods which they could use only through the 
aid of phosphorus. It also aids in seed formation 
and brings the plants into full maturity. In a 
word, phosphorus completes the job of both plant 
and fruit building, and the number of quarts of 
berries produced per acre will depend largely upon 
the content of available phosphorus in the soil. 
Four hundred pounds of acid phosphate per acre, 
or 400 pounds of bone meal, thoroughly worked 
into the soil before plants are set, will furnish 
sufficient phosphorus for one or two crops. 
We might add here that a shortage in fruit pro- 
duction generally may be traced to a lack of avail- 
able phosphorus. Especially is this true when 
other conditions are favorable. Also, it should be 
said, that most soils are amply supplied with phos- 
phorus and potassium, and when this is true, 
humus in the form of barnyard manure or legume 
crops worked into the soil will aid in releasing 
and making available these essential elements. 
Humus warms the soil, makes it retentive of 
moisture, and makes soil conditions very comfort- 
able for bacterial life. There is no soil, except- 
ing rich muck or black soil, but what, to a greater 
or lesser degree, is lacking in nitrogen, and this is 
why we urge growers to use manure liberally.
