I LANCASTER Last summer’s dry, hot weather hurt crop yields over much of the nation It was the worst growing season in six years, according to USDA The yield estimate for corn in 1980 was about 91 bu/A, down from 109 bu/A in 1979 Even so this makes it the sixth best year for corn on record not bad for such a poor growing season How does good soil fertility help THE PIONEER IN BRUSHLESS P.T.O.

Adequate fertility reduces the crop’s water requirement Potassium reduces water loss in plants by lowering transpiration rate and aiding the closing of stomates (pores where plants expel water). Adequate fertility compensates for lower nutrient uptake Such 447 East Third SL Williamsport, Pa. 17701 ' 717-323-1337 717-748-3007 Phase Wire C.B. Amps 100 150 175 225 350 nutrients as N, P, and K need to be swept into plants along with the water Drouth can damage crops worse when nutrient uptake is reduced. A higher fertility level allows more nutrients to be taken up by a water-stressed crop to help lessen the yield loss Crops often respond to fertilizer as well or even better in dry years than in normal years. In Ohio, the first year had ample rain Yields were high (160+ bushel, but there was no response to potash The second year was dry. Yields were down (120 to 130 bushel). But there was a 50 bushel response to K. In Virginia, corn yielded much better in good years than bad years But phosphorus increased yields about the same in both 40 bushel an acre in good, 37 bushel an acre in bad years. In another Virginia study, high fertility more than doubled in the yield in a poor year from 53 to 111 bushel an acre High fertility also gave an excellent increase in a good year 127 to 205 bushel an acre.

When yields were reduced by too little or too much ram, fertilizer gave the greatest response Potassium increased yield 39 bushel an acre in low rainfall, eight bushel an acre in medium rainfall, and 48 bushel an acre in high rainfall A main force behind today’s higher yields is nitrogen. Still more nitrogen will be necessary for tomorrow’s even higher yields, squeezing more bushels from every inch of water Gram sorghum m Texas needed 240 lbs per acre of N for the highest yield and for the greatest amount of gram per inch of water Without N grain sorghum produced 45 hundredweight per acre and 1.9 hundredweight per mch of water. With 240 pounds per acre of N, gram sorghum produced 73 hundredweight per acre and 3.5 hundredweight per mch of water. Fanners get deeper rooting through a healthy, well nourished plant.
