REAGEN TIBBS UPDATES

Region 4

While the temperatures have been sweltering and not much rain has fallen over the last week, crops do not seem to be showing any signs of stress or slowing down. Nearly all of the corn across Logan County has made it at least R1 or R2, with some of the earlier-planted corn already in the R3 stage. The bag is a little more mixed for soybeans. The fields that got planted later or had standing water for much of June are not quite to the reproductive stages yet, but are not far behind. At the Hartsburg Research Plot, a majority of the plants are in the R1 or R2 stage, with some parts of the field not far behind.

The warm temperatures across the County over the last few days appear not to have slowed down crop progress at all. At the Hartsburg Research Plot in northern Logan County, soybean growth is mixed throughout the field. In the parts where there was standing water, plants are in the V5 stage, while the rest of the field is at V10. In the parts of the field that had standing water, there are many empty spaces where plants have not developed or failed to emerge. Volunteer corn is the most present weed at the Hartsburg Research Plot this year, given the late planting date. Other weeds such as Palmer amaranth, Redroot pigweed, and Common waterhemp are also starting to show themselves. While there are Japanese beetles in the field too, they do not appear to be causing significant damage to the leaves, with only a small handful of plants and leaves showing major signs of damage.

Last week brought another 3 to 4 inches of rain across Logan County. This has helped alleviate concerns about drought or dry conditions in the short term. Despite the high winds from some of the storm systems last week, there appear to be very few signs of wind damage to crops. Nearly all of the corn is at knee-height or higher, with some of the earliest-planted corn at V9-V10. Soybeans across the county also look healthy, with the earliest-planted fields in the V5 stage.

Another week, with yet another round of storms and rain across Logan County. Storms on June 17th brought anywhere from 2 to 3 inches of rain. While ditches and low-lying areas are full of water, there does not appear to be any significant crop damage from the high winds that accompanied the rain. This latest round, combined with roughly half an inch over the weekend, will surely add some extra “gas” in the tank for crop growth as temperatures and conditions appear to remain favorable over the coming days.

After a week of high temperatures and little rainfall, Wednesday (6/10) storms brought over an inch of rain to many parts of the County. This will be followed by another round of storms on 6/11. Despite the heavy winds and tornado reports from the 6/10 storms, there does not appear to be much wind damage to crops in much of the County.

While crops across Logan County continue to look healthy, the lack of rainfall over the last week is starting to show some signs of stress, particularly in later-planted fields. The fields that were planted earlier in the season are in the V4-6 stage for corn and soybeans, with later-planted fields in the V2 stage. The first cutting of hay fields has also wrapped up across the county, with the hope of timely rains providing a good jumpstart for regrowth.

Conditions have been mixed for fieldwork in Logan County over the last week. Sporadic rain showers have limited some field operations, but there are no signs of delay for most producers. There are still a good number of fields that need to be planted, with warmer temperatures over the coming days surely to provide the right conditions to get seeds in the ground. Corn and soybeans that have emerged appear healthy, with no obvious signs of frost or heavy rainfall damage.

Crop growth across Logan County remains steady despite heavy rains and cold nighttime temperatures. Most fields that have been planted have begun to emerge, with a few fields still yet to be planted. There do not appear to be many spots that will require replanting due to washouts from heavy rains in late April.

Rains over the last week have been welcome, but have not provided the much-needed relief from drought conditions. If anything, the rain has slowed the harvest progress for many across Logan County. While on the outside rows, some fields appear ready to harvest, there are still many green plants deep inside the fields. Soybeans have been most affected by the lack of rain, with very few green leaves left on the plants.
