There are some challenges associated with planting corn on corn vs. corn following soybeans.  These challenges include different fertility needs and higher residue levels.  There are several steps you can take at planting to maximize yield potential on your corn on corn acres.

 

Seeding Depth.  Corn will develop a better root system when planted 2 to 3 inches deep.  Planting too shallow may inhibit formation of nodal roots and lead to rootless corn syndrome.  At this depth you can expect more uniform temperatures and the seed will be protected from low nighttime temperatures.  A uniform seeding depth translates to more uniform emergence. 

 

Seeding Environment.  Plant corn about 4 to 5 inches off from the previous year’s row.  This will facilitate better depth control and improve seed-to-soil contact.  Avoid planting directly in-between old rows.  Planting in the center of old rows can make setting a planter for uniform seed placement more difficult as some rows will be planted in compacted areas (last year’s wheel tracks) and some rows will be planted into non-trafficked row middles.

 

Planting Speeds. Planting at high speeds impacts the uniformity of seeding depth and seed-to-soil contact.  This can place seeds in different moisture and temperature conditions, resulting in less uniform emergence.  To reduce planter unit bounce and increase uniformity of seed placement.  Take the time to check planter seed placement in each field so you can adjust your speed or equipment as necessary.

 

 

Residue Management. Higher levels of residue can interfere with stand establishment by slowing the warming and drying of soil.  Residue can also affect the furrow opening and closing functions of the planter’s row units.  Consider using row-cleaning attachments on the planter to move surface debris. 

 

If hair pinning residue is a problem, plant deeper.  With a shallow planting, openers are pushing downward on the residue rather than cutting it.  A 15-inch diameter disk opener cuts residue most efficiently when operated about 2 to 3 inches deep.  Maintain sharp cutting edges on openers to quickly cut through residue.

 

Optimizing Fertility. Corn removes more soil phosphorus and less soil potassium per acre than soybean.  A one-time switch to second-year corn will not greatly affect soil P and K levels, but if your fields have been planted to corn for multiple years you should monitor soil P and K levels and adjust fertilizer application rates as needed.  Consider using a starter fertilizer containing N and P in a 2×2 placement.  Research has shown a positive response to starter fertilizer when soil test P levels were below optimum.

Iowa Fertilizer Company (OCI) announced that it will hold a ribbon cutting ceremony this Wednesday, April 19th.    The $3 billion Wever, IA plant is the largest capital investment ever in the state of Iowa.   When ground was broken was broke back on November 19, 2012, it was a $1.4 billion complex.   The plant capacities are 214,000 tons per year of sellable NH3, 460,000 tons per year of Urea, 1.65 million tons per year UAN and 346,000 tons per year of DEF.   Being a new plant, it has the flexibility to change products.   Last Thursday, April 13th the first NH3 was on spec and is currently  producing 2,000 tons per day.   Later this week Wever will start making UAN.

About IFCIowa Fertilizer Company is a leader in the fertilizer industry. The plant in Wever is the first greenfield nitrogen fertilizer facility constructed in the United States in nearly 30 years. With state-of-the-art production, the company will help provide farmers in Iowa and around the country with a stable, domestic supply of fertilizer while also utilizing industry-leading technology and environmentally sustainable processes.

WHEN and WHAT to PLANT

With planting starting, I have been asked, “Is it too early?” and “Which hybrids should I plant?”  Soil temps have been hovering around 50° at the 4” depth. However, if you look at some of the reports on the ISU soil temperature site, you may notice some very odd readings, but for the most part, soils are warm enough to begin planting.

If soils are dry, planting can sure take place, but keep in mind there has not been any long-term data showing an advantage to planting this early.  Many growers can plant corn in a week or less so there is no reason to hurry. Even though the forecast looks favorable there is no benefit in trying to get everything planted in the first early window.  It’s easier said than done, but planting only a portion of your fields may be the best strategy.

Hybrids with the strongest emergence if planting in potentially tougher conditions are DKC44-13RIB, DKC48-12RIB, DKC48-56RIB, DKC49-29RIB, DKC49-72RIB, DKC50-82RIB, DKC52-68RIB, DKC53-56RIB, DKC53-68RIB, DKC54-38RIB, DKC55-20RIB, DKC57-97RIB, DKC58-06RIB, DKC61-54RIB, DKC63-60RIB  and DKC64-34RIB. Hybrids to avoid planting early or in tougher conditions include EBs, DKC45-65RIB, DKC46-20RIB, DKC49-94RIB, DKC52-84RIB, DKC57-75RIB, DKC62-77RIB  and DKC62-97RIB.

The 48-hour forecast is your friend.  If there is a foreseeable drop in temperature and rain is predicted, it is best to wait, even though planting conditions are good.
