Saturday, April 6.1968 SECOND SECTION Spring Sends Out A Call \ _ Even To Stored Corn When spring creeps north, na ture puts out an undeniable call to all living organisms. Even corn in storage "hears” and tries to answer the call to reproduce. Everyone knows that corn be gins to sprout when it is plant ed in the warm, moist soil, but did you know that even in the crib, far above the ground, corn “knows" when spring arrives? At this time of year, corn goes through a physiological change. Even though it is, not planted in the ground, corn seed will try to carry out its repro ductive function It may not ac tually sprout, but the increased activity within the kernels will produce enough heat to spoil the crop. This can happen even when the corn has been dried to 14 or 14V2 percent moisture. Says John Crothers, Extension marketing specialist at the Uni versity of Maryland, “if you have shelled corn stored on the farm or in commercial bins, check it carefully for heating. One of the first obvious signs of heating is the odor of sour corn —but by that time it is too late.” “You have to be on the de fensive if you want to beat na ture at her tricks he adds “If you don’t have heat sensors al ready in the bin, you’d better find some way to take tempera ture readings at several areas. Heat sensors on the market can be installed in most bins ” Crothers says the heating problem is likely to be worse if the corn contains large amounts of foreign material (weed seed, pieces of cob, broken kernels) which forms pockets and may hold a little more moisture than the rest of the bin. “What can you do if the heat sensors do show hot spots? The best thing is to turn the corn by transferring it to another bin. This will be certain to move and aerate- all sections of the bin. It also breaks up any poc kets of foreign material." Croth ers adds. “This job should be done on a sunny day if pos sible.” But even after the corn is moved to another bin, don’t be complacent, Brothers warns. All your efforts may be wasted if the rebinned corn begins to heat again. Usually you can keep the corn in good condition if you aerate it with forced air. Grain can be kept safely through the summer if it does not heat or is not allowed to get damp. But you have to know Mother Na ture and her tricks if you want to stay on the defensive.
