Methods are presented here for modernizing Iowa pastures. The recommendations are based largely upon the results of experimental studies. These studies have shown that the returns from many pastures can be nearly doubled by liming, fertilizing, using better kinds of grasses and legumes, and by practicing good grazing management.

Those interested only in the recommendations for improving pastures will find them under appropriate headings. More critical readers may also wish to study the data which are the basis for many of the recommendations. These are contained in the appendix. The results reported will be of particular value to county extension directors, soil conservation workers, vocational agriculture instructors and farm managers.
