A good, dense nesting groundcover can be created <br />by using a mix of 1/2 lbs. sweet clover, 2-3 lbs. alfalfa, 6 lbs. <br />i ntermedi ate wheat, and 4 1 bs. ta 11 wheat per acre. <br /> <br />Both floating and ground based nests as shown in the sketches should be <br />provided inappropriate 1 ocati ons.
