seal was j at Mrs. The chances are seven to one that farmers could have had more corn this year. Extra doses of nitrogen would have paid well this season on 70 per cent of the land in the corn belt. Of all the plant food elements, nitrogen is the one most often lacking--and the most expensive to buy. An accurate, easy to use test has been developed which tells when a plant starts to get hungry for nitrogen, long before it starts to show hunger signs. And the test isn't difficult to make. It involves the use of a nitrate testing powder developed by Dr. Roger Bray, of is m. a University of Illinois agronom- at 1st, which has been released for general farm use. With corn, you will want to start testing stalks about the middle of July in 15 or 20 spots over the field. Keep testing every two weeks up until the last of August. To test corn, you simply split the stalk with your jaekknife and apply the powder to the split surface. Press the stalk together to assure wetting of the powder. If nitrates are present, the powder turns pink. By the degree of color, you can judge when side-dressing with nitrogen fertilizer is needed. If your test shows nitrate lack, and you think there'll be enough ground water or rain to dissolve fertilizer, you can side-dress with nitrogen fertilizer thru the first week in August. Apply two pounds of pure, nitrogen for each expected bushel of increased yield. Since it moves in the soil water, nitrogen is the first element you'll lose to dry weather. A soil too dry to continue releasing nitrogen will still have some phosphate and potash available. Thus, by adding chemical nitrogen, you can, in effect, retard drouth damage. To test soil before planting, put one part each 01 soil and testing powder in a small bottle and add seven parts of distilled water. Shake and let the solution settle. A strong pink color means nitrogen is being released fast enough to start the crop. If you get no color, you want to step up your starter fertilizer a little. You can use this same test at wheat-seeding time. With small grains and pastures, you can use the test any time during the growing season, especially during a cold, wet spring. If your pastures don't seem to recover from grazing as fast as they should, test the grass for nitrogen hunger. To make the test, take few leaves of the gram or grass and fold them into a sheet of filter paper available at any drugstore. Sprinkle a little of the test powder on the paper and fold the paper over Then give a good squeeze with a pair of pliers to squeeze the moisture from the leaves to wet the powder. There will be pink stains on the paper if the gram or grass has been ing nitrogen. Use your own judg-, ment after testing. More fertilizer may not always be the answer a complete soil test should be obtained. --Successful Farming.
