Weather is always a conversation starter at the coffee shop, but this spring the weather has not only been the starter, but the main topic of conversation. The last month has provided numerous weather systems that have made the thermometers go up and down like a yo-yo, and therefore, put a major wrench into a lot of growers’ planting plans. Despite the frustration of the delayed planting date, the moisture was and still is a welcome sight for the region. Unfortunately the entire region did not receive all of the rains that came with these systems. The western part of Nebraska is still extremely dry and continues to be in the “severe drought” stage. Even with the obstacles, planting is slowing moving along. Planting progress is all over the board though; I have areas where growers are finishing up their corn acres and others that are just starting. Overall as a region, I would estimate that we are 35%-50% completed (corn acres).
As we trench through this planting season there are just a couple things I would like to touch on. Planting is the most important operation you will have this season. It is the one operation that will have an effect on every decision you make throughout the growing season: weed control, side-dress nutrients, irrigation, and harvest. Accurate depth, spacing, and soil-to-seed contact plays a huge role in your yield outcome.
Depth– too shallow and the crown is forced above the soil surface dramatically affecting nodal root development; too deep and you risk the plant not reaching the surface (common in colder soils and high residue).
Spacing– is critical for maximum sunlight absorption, weed control and even nutrient distribution.
Soil seed contact– wet planting conditions are prone for sidewall compaction. Make sure that the seed firmers are accurate and that the furrow is closing properly to avoid the seed drying out.
Again, as you start planting or continue to plant, remember to get out and check your depth, check your spacing and your soil-to-seed contact at every field and sporadically throughout as conditions change. These small things can make the difference between a viable grain producing corn plant and essentially a corn weed.
With a cooler wetter forecast model now being discussed, there are some things to be aware of as the seeds begin to grow. Cooler/wetter soils will promote more seedling diseases such as pythium, phytophthora and fusarium. These diseases can cause “dampening off” and influence later infections of stalk rots. Also, cooler/wetter soils tend to increase certain insect activity such as wireworm, seedcorn maggots and grubs. Shortly after the corn emerges, one pest to be aware of with cooler weather is black cutworm. Corn stages from VE-V5 are at a greater risk because the larvae can chew the stalk completely off at the base of the plant.
This spring could not be more different from last year. There are obstacles to overcome and adjustments to be made. If there is any way we can help please contact your local DSM or Agronomist and let us know. Thank you for your business and have a safe planting season.
