This report is a summary of progress to date in one phase of the study
designed to determine differences in the results obtained when cattle
consume forage grown on limestone or sandstone soils.
In any study of this sort there are many variables which cannot be completely
controlled or eliminated. Regardless of the care used in selection
pastures and meadows will differ somewhat in type and yield of forage:
Rainfall differs, even on pastures within a few miles of each other. And
the previous histories of the pastures are somewhat different All these
and many other variables affect the results obtained. Therefore, several
years of comparisons will be needed before definite conclusions can be
drawn. Results obtained to date should be looked upon as suggestive
rather than as final conclusions.
