Show Soil Management Aid To Increasing Yields Farmers Co-operating in Test Get Good Results Larger yields of grain and better Stands of hay are becoming increasingly important these days when the demand for meat and dairy products for war and civilian needs has reached such record peaks Whether the output of these crops is large or small on a particular farm depends largely on the condition of the soil that produces according to C. J. Chapman of the college of University of That such crops respond to soil management is from tests carried on in a number of Wisconsin counties in which fertilizers containing phosphorus and potash were applied to small grains and of clover and Farmers co-operating in the tests laid out demonstration plots on their leaving one area The results in the form of grain yields and hay crops that followed them in the rotation were checked and The harvests showed that not only was the output of the small grains but the production of hay that followed in the rotation was greatly The tests that the soil improving treatments had a valuable carry-over Typical of the results obtained tests on farms in Portage coun- m Allen G.
