KCGA said these factors encourage corn growth on more acres. State corn acreage also has been increased by irrigation in western Kansas and other areas.
Back in 2000, agricultural economists at Kansas State University were discussing possibilities that corn might supplant wheat as the top crop in Kansas, crowding off both wheat and grain sorghum acreages.
By mid-October some of the early predictions of a surging corn crop had begun to dim, even though the crop still was very good. KASS lowered its estimates to 3.8 million acres of corn to be harvested with a total yield of 493.2 million acres.
Kansas was still 10th among the states in corn production.
KASS estimated the sorghum grain harvest was at 209 million bushels, soybeans at 115.2 million bushels and sunflowers at 310.8 million bushels. The wheat crop came in at 356 million bushels.
Even back in 1878, the very first year the Kansas State Board of Agriculture came out with a biennial report, the agency was analyzing whether an increase in wheat acreage could lead to a decrease in corn acreage. But corn acreage in 1878 still topped all other crops grown at 2.4 million acres.
Locally, the biggest advantage the renewed focus on better varieties of corn gives Marion County producers is flexibility in their farm programs, according to Rickey Roberts, county agricultural extension agent.
Roberts calls corn in Marion County ?a high risk, high potential reward kind of a crop.?
He said county farmers were sharing in the general enthusiasm for planting more corn last spring because of the historically high price for corn.
?It looked like a good opportunity for profit,? Roberts said. ?But in the last 30 to 45 days, with the declines in prices, a great deal of that enthusiasm has tanked.?
Roberts said all producers are aware they face a challenge with corn because of its high demand for inputs. It requires high fertilizer input and adequate rainfall. It leads to a quick make/break margin.
?The decision for planting corn has to be tied very closely to its price,? Roberts said.
Beyond the price issue, Roberts said Marion County farmers also have to realize they are on the very western margin of good corn-growing country. Rainfall must be adequate, but a drier climate with more drought can quickly limit corn production here.
An even more significant factor that producers here face, he said, may be the quality of the land. Marion County has only a few deeper-soiled creek valleys really suitable for growing corn. The large majority of the cropland is in thinner-soiled uplands, he said.
Further east, soils in the corn belt have very deep profiles.
?So really,? Roberts said, ?our soils are of a type where corn should generally only be grown in the bottoms. So much of our upland is not suitable for corn production that it becomes a very high-risk crop.
?It?s also a pretty expensive crop to plant. Beans and milo are so much more likely to be reliable crops on these types of soils that it takes us back to needing really high prices to take the risk.?
Roberts said the new genetics ?help tremendously? in making corn a more attractive crop, but they don?t change the fact that the county has thinner soils.
?The improved genetics also come at a cost,? he added. ?The new hybrid corn seed is not the cheapest thing around.?
Roberts said when farmers are looking at planting increased acres of a crop previously not grown in high quantity here, beans usually are chosen ahead of corn. He said soybeans can be more drought resistant and they have a ?locked-in herbicide advantage? because they have been genetically engineered for Roundup resistance.
Roundup can be sprayed on soybeans to kill weeds without hurting the beans, leaving ?very clean fields.?
Soybeans are also a legume, utilizing bacteria to take nitrogen from the air to create nitrates for plant uptake, therefore cutting fertilizer out of the cost equation, Roberts said.
Corn can be used to add flexibility and diversity to a farm program, Roberts said, particularly if a producer also raises cattle.
?If it is too hot and dry for the corn to pollinate to make grain, it can generally be cut for silage to feed livestock,? he said.
?It can have high feed value. So, sometimes the decision on whether to plant corn has to directly be related to whether a farmer also raises livestock.
?I repeat, it?s a high-risk, high-reward type of a crop. And, we aren?t ever going to be able to change the kinds of soils we have here.?
