{Continued from Page 11. ) as before, it is seeded to a mixture of cow-peas and buckwheat. 
The resulting growth seems almost magic for in a few weeks both the buckwheat and cow-peas are 
in bloom and the growth becomes so rank and dense that it is difficult if not actually impossible to 
progress far into the field afoot. Just before the seed ripens this growth is rolled down, cut up with disc 
and plowed under. The buckwheat adds humus and the cow-peas, (another legume), both humus and 
additional nitrogen. After this has been thoroughly worked into the soil and a perfect seed-bed again 
formed fall has arrived and the ground is seeded to oats. 
The Final Rotation Crop 
Oats serves a double purpose; — provides to a certain extent a winter protection against the porosity 
caused by alternate freezing and thawing and its decay renders the soil mellow and easily worked. 
During the winter a top dressing of stable manure is applied at the rate of fifteen tons per acre and 
the oats and manure are plowed under just as early as the soil can be worked the following spring. The 
manure furnishes nitrogen, potassium and phosphorus in quantities which with that already furnished 
by the rotation crops, makes a properly balanced plant food. 
Again it is worked and with spring tooth and disc harrows and rolled until it forms a pulverized 
seed-bed and after being marked into rows and cross marked, it is again ready for Kellogg Pedigree Plants. 
We Practice and Recommend Spring Planting 
We practice what we preach by setting our plants in the spring exclusively (during April or May) 
as we have found through many years of experience that spring setting gives surest results in the North. 
In the Southern States plants may be set with success either in the spring or fall. 
Kellogg Pedigree Plants, — Yearlings 
Every spring the fields which have just produced plants are plowed at the close of our shipping 
season and put through our crop rotation process. This thoroughly renovates the soil and supplies in 
proper proportions nitrogen, phosphorus and potassium, the essential elements of plant food together 
with an abundance of humus, the medium through which plants feed. It is what might be termed a re- 
generative process because it actually renews or rebuilds the soil. 
It is impossible to find any plants on the Kellogg farm more than one year old except in our testing 
and experimental beds, and the mother plants in our propagating fields. In digging plants for shipment 
all mother plants are thrown out Only their offspring, — strong, sturdy, young runner plants, are used 
in filling orders. This assures Kellogg customers young blood, full of life and stamina. When such 
plants are set in the customer's field or garden, growth is rapid and vigorous. 
Answering an Appeal for Moisture "When Nature Refuses" 
During periods of drouth, our Skinner Irrigation System is relied upon as crop insurance. It's value 
is not limited to furnishing moisture to Kellogg Pedigree Plants alone for it is just as frequently used 
in supplying moisture to our rotation crops. 
Like the good Samaritan of Sacred History, it brings water from the 
nearby stream and applies it soothingly to the thirsty plants in the form 
of gentle, mist-like, refreshing rain which thoroughly saturates the 
ground to their very root tips. If drouth prevails at seeding time, its 
near-natural-rainfall insures prompt germination of seed which is nec- 
essary to a successful crop. It likewise is depended upon to furnish 
an uninterrupted supply of moisture 'whenever Nature refuses'. Often it 
is the only means of saving the crop. 
This system enables us to furnish Kellogg Pedigree Plants with mois- 
ture throughout the growing season, insuring unhampered and unchecked 
development both of plant and root systems. 
With this dependable substitute for natural rainfall, the intense 
and prolonged drouth of 1921 (the mo.st serious in many years) was not 
the serious matter with us which it otherwise would have been. 
There is also another way in which our Skinner Irrigation System 
serves our customers, for it gives us an increased production of thou- 
sands of plants per acre. As the size of our plant crop bears a direct rela- 
tion to the prices of Kellogg Pedigree Plants, you can readily see that 
this increased production is an important factor in enabling us to quote 
the low prices given on Page 66 of this book.

heavily rooted one-year-old plants of

Hoeing, Cultivating and Removing Blossoms 
Our propagating fields are hoed and cultivated repeatedly during the 
growing season and all blossoms are removed as fast as they appear. We
