2-F DES MOINES' SUNDAY REGISTER My 12, 1968 New Formula for Safe Corn Storage if nit-. using a "reference curve" and formula he developed. Held within these limits, corn loses some quality but keeps Its market grade. If held longer, the loss in quality causes grade to be lowered. Saul developed his formula after several years of measur-' Ing how much carbon dioxide shelled corn produces at various moisture contents an4 temperatures.

The amount of carbon dioxide that corn produces is an accurate indicator of the amount of dry matter it loses at the same time. Loss of dry matter is a major cause of deterioration in quality. Saul emphasizes that the chart, while accurate', is only a guide because other factors, beginning with harvest, influence storage life of corn. If there are delays, part of storage time is used up before the corn gets to the storage area. Rodents and insects also reduce storage life and should always be controlled.

In Saul's studies, the corn was brought to the storage area quickly and aerated at once to maintain temperature. vH 'tit J5f4 Corn Storage Chart Ifeflytil mum TT Storage Air Temperature (Degrees) 35 40 45 50 55 60 65 70 75 Loss in corn quality can be longer than the times given in corn could also suffer a loss in times indicated, this isn't likely.

Field shelling is a major advancement In harvesting efficiency, but such corn often has a very high-moisture content. It should be dried at once to preserve quality, but this is not always possible.

Fanners forced to store high-moisture corn rely) to a large extent en Judgment and experience to estimate how long it may be stored. More accurate predictions will be possible with the new chart. A U.S. Department of Agriculture engineer, R. A.

While the quality if kept less than the 3'M 3 ing 6 millions acres of soybeans," he said.

"There is something different about the soybean plant. It fluffs up and loosens the soil so that when it is plowed, and the winds come, much of it starts to move. "It could be that farmers can disk such fields in the spring to plant corn, and avoid the fall plowing that we know contributes to Iowa's wind erosion problems." Mendell noted that this spring Iowa has sustained wind velocity of up to 60 miles per hour, at a time when soil conditions generally have been dry. With a high extent of fall plowing, and very little crop residue left on or near the surface, severe wind erosion has resulted. ityj WIND- Continued from Page One plowed soybean field creates the most wind erosion problems."

Another "loss" seen by Moon is the damage to Iowa'i wildlife. "A lot of this dirt has piled up in areas that normally provide cover for game," he pointed out. "In many cases, this Is all of the cover the wildlife has." CONCERN ABOUT wind erosion In Iowa figured into the development of a new cost-share practice under the Agric ultural Conservation Program (ACP) as administered by the Agricultural Stabilization and Conservation Service (ASCS) this year. The new practice provides for payment at a rate of $1 per acre to farmers who leave strips of unplowed land in their fields. This ACP cost-share assistance is available in 27 north central counties.

Farmers participating agree to not plow the strips until April 1, 1969. 5 the hopes of conquering the wind erosion problems on the minimum tillage approach. "A sound mulch management system, keeping plant residues at or near the top of the soil profile, and mixed in with the soil, should help not only to fight wind erosion, but hold moisture as well," Ballantyne said. liriLSON T. MOON, state conservationist for Iowa, said that SCS efforts are being made to develop more interest in mulch or rninimum tillage in the northern half of the state.

"This is the area where the most severe wind erosion problem exists," Moon said. "This is where much of the land is row-cropped and consequently is subject to wind erosion." Moon pointed out that the silt piling up in ditches, along fences and roadways, is a serious economic matter for county road departments as well as a loss to the farmer and land-owner.

The conservationist feels that farmers have several methods of combatting such soil loss: 1 Creating more crop residues near the surface to help hold the soil. 2 Leave the soil surface rough.

3 Leave narrow strips of corn and soybean stubble un-plowed in the fall to help break the steady blowing of the wind across the fields. 4 Start efforts to develop a higher organic matter content of the soil, in keeping with good land use. 3 Use minimum tillage or mulch tillage practices, which tend to leave the soil surface rough and to loosely incorpo-ate plant trash into the upper areas of the soil.
