Fertilizers boost yields of small grains, grasses and legumes
Is Version Of
Corn is king in Iowa. But corn should not be grown continuously. It should be rotated with small grains, clover or alfalfa. Such a rotation insures a good nitrogen level in the soil, cuts down on erosion, and helps keep the soil in good tilth. These factors in turn result in higher corn yields. Too often we neglect or omit our small grains and seedings because they don’t give us the high cash return of corn. One way to make them more profitable is to increase their yields. You can give the yields a real boost with fertilizers.
There are two ways to use fertilizers on small grains and forages— the,right and the wrong. Among other things, the right way involves using the correct kind and amount of fertilizer, applying it effectively to the soil and at the best time. You must know how to do these things. They will determine the returns you will get from your fertilizer. To give you the best possible information on these points, the Iowa Agricultural Experiment Station has conducted several hundred experiments on the fields over the state during the past few years. It is the purpose of this bulletin to give you the information gathered from these experiments along with other pointers to help you in your fertilizer program.
