WISOONSIII YMELDS ON BE STILL LARGER But Wisconsin cannot afford just to lead the United States in yields. In Europe, where ten times as much fertilizer is used as in Wisconsin, the yields are still far above those of Wisconsin. Take, for example, the average yields in one country: wheat, 33 bushels; oats, 55 bushels; barley, 42 bushels; rye, 30 bushels; and potatoes, 200 bushels. This European country spends $2.50 an acre on fertilizers for every 24 cents spent in Wisconsin. Fertilizers other than manure are used on less than 1 per cent of Wisconsin farms. In Europe fertilizers are used on nearly every farm. One reason that the World War could last so long is found in the use of commercial fertilizers by the blockaded central powers. NATURE SUPPLES FERTLIZER STOREHOUSES Great deposits of phosphorus and limestone (calcium) are found in the United States. Nature has been storing them for our use for many, many years. Why not use them? The air contains millions of tons of nitrogen. Clover, alfalfa, and soybeans can gather it for us. Why not let them? WHAT FERTIIZERS WILL DO IN WISCONSIN The dollars and cents value of fertilizers on the different kinds of soil in the state can be illustrated by actual results from the use of the different kinds of fertilizers on Wisconsin farms. Here are some ex- amples-they will interest you, especially the one describing the kind of soil found on your farm. On very poor sand at Hancock this last year, rye without fertil- izers yielded at the rate of six bushels an acre, while with 500 pounds of a 4/12/0 fertilizer costing $8.75, the yield was 22 bushels. The grain sold at $1.60 a bushel, giving a net profit of $16.85 an acre. On the same land, potatoes on a light clover sod without fer- tilizer, yielded 89 bushels, while with an addition of 500 pounds of a 4/10/0 fertilizer costing $8.15, the yield was 120 bushels. They sold at 80 cents a bushel, giving a profit of $16.65 an acre. Corn on the same poor sandy soil following grain and without fertilizer yielded 18 bushels an acre, while on a clover sod with an
