A Power Sampler Of Undisturbed Soils, Wesley F. Buchele
A Power Sampler Of Undisturbed Soils, Wesley F. Buchele
Wesley F. Buchele
An undisturbed column of soil is required to measure the physical properties of soil and the distribution of roots, insects, and fertilizer within the soil. Because of the excessive expense of digging a trench around an undisturbed soil column, research on the physical properties et cetera of soil in the undisturbed state has been limited.

A tandem tractor composed of two tractors hooked together and controlled from the rear tractor has been built at the Agricultural Engineering Department, Michigan State University. It was tested on sod, plowed, and plowed and disked land. Results indicate that the tandem tractor can provide the farmer with a versatile power unit: one four-wheel drive tractor for pulling heavy loads; and two two-wheel drive tractors for pulling light loads.

Increased research effort has been directed toward the solution of soil compaction problems in the past few years. Research workers dealing with these problems have been handicapped for at least the following four reasons: 1 Lack of definition and understanding of soil stress and soil compaction; a need for a suitable mathematical model 2 Lack of suitable recording equipment for measuring changes in soil physical phenomena, particularly soil compaction 3 Lack of basic engineering information about the mechanics of agricultural soils 4 Lack of adequate information showing the effect of certain parameters (soil moisture, soil type, and others) upon soil …

To study the soil compaction problem, the amount of compaction change at every point in the soil resulting from loads applied to the surface must be determined. If this change can be calculated, the effects obtained from varying the loads can be observed and thereby information gained which will permit predicting and possibly controlling compaction. Such calculations require a suitable theory of soil mechanics to formulate a mathematical model describing the soil.
