Time to Begin Early Crop Scouting in 2011

Many Midwest farmers will wrap up the 2011 planting season this week, but there won’t be much rest for the weary. As soon as seed is in the ground, it’s a good idea to start scouting fields.

Post-planting is an ideal time to begin scouting one’s crops. Many soilborne pathogens strike as soon as the seed begins to take on water; others strike young seedlings. Because seeds can germinate quickly and emerge in 3 – 5 days, it’s not too soon to start walking your fields.

Check plant populations, evaluate stands and be on the lookout for early summer diseases. Is there a germination problem? Do you see effects of chilling or crusting?

Assessing your situation ASAP will allow you to formulate a plan while there’s still plenty of time to implement it. You could replant in parts or in all of a field now, so you can attain the yields and returns you want this fall. Information on corn replanting decisions is available from www.agronext.iastate.edu/corn. Click on the “Planting” topic, then click on the “Replant Decision Aid Calculator” tab and use that tool and related information to help make a replant decision. For a resource on soybean replanting decisions, go to www.extension.iastate.edu/publications/pm1851.pdf.

Another benefit of evaluating current stands is to help you determine what adjustments should be made before planting next year’s crop: Do you need to adjust your planter settings or your planting speed?

Once you get past the mechanical issues, look at the disease pressure. If soybeans are damping off, perhaps next season you should opt for seed-applied fungicides? Do you need to pay closer attention to a particular soybean brand or corn hybrid’s disease rating? Seed selection is one of the most important decisions affecting yield.

Crop Report 05/09/12: Planting is a Test of Patience

In spite of widespread rain showers during the past week, corn planting remains ahead of schedule. Iowans had planted 64% of their corn acres by Sunday, which is ahead of last year’s 52 percent and the five-year average of 58 percent. Nebraska advanced to 74% of their corn acres planted and Minnesota to 73%. Just 34% of Wisconsin’s corn crop was in the ground as of Sunday, that’s 16% more than a week ago and 4% ahead of the 5-year average. Soybean planting is a bit slow, as well.

“We’re still within the window to plant corn and achieve high yields. Farmers have until late May to get their seed in the ground,” Roger Elmore, professor of agronomy at Iowa State University with research and extension responsibilities in corn production. “It’s far better to wait for good soil conditions than it is to ‘mud in’ your seed.”

Planting early ensures the best yields if weather conditions are right. Planting in wet soils can lead to other, yield-robbing situations like compaction. Forty-one percent of Iowa’s corn crop was planted in just 4 days, so it won’t take long for the remaining seed corn to get out of the bag and into the ground.

Central & Eastern Iowa Crop Report: May 9, 2012

Temperatures warmed up, so the corn that had been planted earlier continues to move along rapidly. Even with a tough weather week, some planting was achieved in areas and looks like we have moved to 75% complete. Rain moved through the area with amounts all over the board, so that slowed planting progress in many areas. Now we’re waiting for conditions to improve and fields to dry. I’m hopeful we can wrap up corn planting by my next report.

Most producers are moving to soybeans as they finish corn. Caution needs to be taken to wait for improved seedbed conditions before we plant. With the amount of rain and warmer weather, we want to avoid heavy crusting and compaction that may compromise good emergence. Soybeans are only 10% planted in the area, but will proceed very quickly as weather permits.
