REPORT OF PROGRESS, 1920-1938
Experiments on Newton Fine Sandy Loam
How to Treat This Kind of Land
Both lime and manure or mineral fertilization, especially potash, are essential for the production of reasonable crop yields on this land. Neither lime, manure nor fertilizer used alone is as effective as when used in combination.
This soil is strongly acid (pH 4.5) and requires from 3 to 4 tons of ground limestone per acre.
Adopt a system of cropping in which a legume appears at least once in each round of the rotation. Either corn, oats, mixed clover and timothy two years or corn, soybeans, oats, mixed clover and timothy one year are good rotations for this land.
Feed as much of the crops as practicable and carefully conserve and return the manure for corn.
Fertilize the corn with 100 pounds 0-12-12 fertilizer in the hill.
Where manure is not available for corn drill 250 pounds 0-10-20 with the oats crop.
This field, known as the Pinney-Purdue Experiment Field, consisting of 67 acres, is located one mile east of Wanatah in LaPorte County on Newton fine sandy loam, which is a very acid, dark-colored soil occurring in various sections of the Kankakee region. This land was given to the Purdue University Agricultural Experiment Station in 1919 by the late William E. Pinr.ey and his daughter, Mrs. Myra F. P. Clark, for the establishment of a permanent experiment field.
