When considering corn planting for 2012, one certainty is that the growing season will be different than past growing seasons. However, there are some tactics, including planting at the proper depth, that will help overcome weather challenges in the crop.
Corn planting depth is easily measured shortly after emergence. Taking care to dig up as much of the plant as possible, the distance between the growing point, also known as the first node or crown, and the soil surface is usually three-quarters of an inch deep when planted at recommended planting depths. Measuring the mesocotyl, the area between the seed and the growing point, then adding three-quarters inch, will determine planting depth in the soil. Under ideal conditions, corn can emerge in a week to 10 days. Under more stressful conditions, such as wet soils or extended periods of temperatures below 50 degrees, corn may take up to three weeks to emerge.… Continue readingRead More »
