Feed The Farm What! Feed the farm-feed the soil? Yes, the mother that feeds us must herself be fed. With the light and heat of the sun, Mother Earth can put things together in plants as food for us-if she has the right things to work with. These things we call elements, and among them are carbon, nitro- gen, phosphorus, potassium, calcium, magnesium, sulphur, iron and water made of hydrogen and oxygen. The soil usually contains a good quantity of most of these, but often there is a lack of some of them. You know something is lacking when the crop does not make a good growth, but you cannot be sure except by making experiments in which different elements are added to the soil, or by a chemical analysis. Nitrogen, phosphorus, calcium, and magnesium are most often lack- ing in upland soils. Marsh soils usually have an abundance of nitrogen, but are lacking in potassium, phosphorus, and, when acid, in calcium. WISCONSIN CROPS ZXCZL IN YIEDS The yields of Wisconsin crops are already good, better in fact than the yields of the same crops in other states. Wisconsin yields in 1918 were: Spring wheat ... ...... 24.6 bushels - Winter wheat ... ...... 22.0 bushels Oats ......... 46.6 bushels Barley.... 35.7 bushels Rye .... 17.6 bushels Potatoes .... 112.0 bushels In all of these crops Wisconsin has the highest average yield among the states growing any considerable amount of the crop. These yields ar6 due to high yielding seed-and manure. 1 :. .
