On the Contour- More Corn, More Beans

One way that Iowa farmers who have sloping land can produce more per acre and per man is to plant their crops on the contour. We have thought this is true, but during the past year the Iowa Station and the Soil Conservation Service in cooperation with Iowa farmers conducted some experiments to try to get some measure of how m u ch increase one could expect by planting corn and soybeans on the contour as compared with planting up and down hill

Hold Topsoil-Contour!

For the past several years we have been calling attention to the increase in yields obtained with corn, soybeans and other crops planted on the contour on sloping land as compared with yields from adjacent areas farmed the up-and-down hill way

Around the Hill Farming

Farming around the hills instead of up and down them pays. We are convinced of that after 4 years of comparing yields, measuring soil and water losses and observing the difference in power that contouring takes as compared with up-and-down hill farming

Inoculate for More and Better Soybeans

For many years the experiment station folk, we of the Iowa Station included, have been telling you to inoculate your soybean seed. But just how much increase in yield can you expect from inoculation, and will it improve the quality of the crop produced

Contouring Paid in 1943

Iowa farmers who farmed round their hills — the contour method — in 1943 got more corn, oats and soybeans to the acre than the farmers who farmed up and down their hills. At least this was the conclusion we reached after comparing yields of these crops grown by the two methods side by side in the same fields. We had results from 61 fields of corn, 38 of soybeans and 18 of oats in different parts of Iowa

More Seedbed Studies

Last year we continued our study and comparison of the disk, lister, subsurface tiller and plow for preparing seedbeds for corn. This was the fourth year that these implements have been compared, but since they perform differently on different soils, we do not believe we have the complete answer about them yet. In only 1944 and 1945 have they been studied at a sizable number of locations and on several soils
