Use the G.L.F. Super Plant Foods 
Corn reacts quickly to fertilizer and the experience of many farmers shows that 
yields will increase as the application of fertilizer is increased. G.L.F. Super 
Plant Foods will not only produce larger crops, but offer more fertilizer per 
dollar spent—they all contain 24 or more units of plant food per ton. Whether 
you raise corn for grain or ensilage, the liberal use of recommended grades of 
G.L.F. fertilizers will pay off in greater yields on every acre. 
5 Steps to Bigger and Better Corn Crops 
1 » Lhe first essential is a well-drained soil having reasonable depth. 
- th Choose a G.L.F. high-yielding hybrid adapted to your area. Check the Hybrid 
Seed Corn Chart at your G.L.F. service agency. 
Space the corn properly. Cornell University agronomists recommend 18,000 
stalks per acre. In Pennsylvania, 14,000 stalks are recommended for the most 
productive soils and 12,000 for normal conditions. In New Jersey, most corn is 
planted in hills. Recommendation for heavy soils is: 3 seeds in hill in 3’ to 31’ 
rows; on light soils: 3 seeds per hill in 314’ to 4’ rows. 
4. Fertilize liberally with G.L.F. Super Plant Foods. It takes about 160 pounds of 
actual nitrogen per acre to produce 100 bushels of shelled corn or the equivalent 
thereof in silage. This nitrogen may come from manure, legume sod or G.L.F. 
fertilizer or a combination thereof. Remember that not more than 17 the nitrogen 
in manure is available the year applied. 
5 Keep the growing corn free from weeds through cultivation and the use of 
* G.L.F. Weed Killing Chemicals.
