Iowa farmers are coming more and more to realize the value of growing legumes, not only because of their value as hay and forage crops, but also because of their soil-enriching properties. The fact is often overlooked, however, that If the legume Is not well Inoculated, or supplied with nodules on the roots, It will have less \value for feeding purposes, and Its beneficial effects on the fertility of the soil will be very materially reduced.
Well inoculated legumes are essential in every well planned rotation to build up and maintain the fertility, or crop-producing power of the soil. Large beneficial effects are evidenced on the succeeding crops, which make the practice distinctly profitable. Hence, farmers are urged not only to grow more legumes but to grow inoculated legumes.
