Harvest has officially begun in Logan County, with some corn fields being harvested earlier this week. A lack of significant rainfall, combined with the high daily temperatures over the last couple of days, has pushed plants toward harvest. Some corn and soybean fields are still too green, so it remains to be seen how the forecasted high temperatures over the weekend will impact their readiness.

Rain showers earlier this week brought much-needed moisture to the area, giving some fields a boost. Most of the corn in Logan County has entered the R5, or dent, stage, with some fields still in R4, or dough. Soybeans are showing similar progress, with most fields in the R5 stage. The growing season is nearing its end, and some plants are beginning to show signs of full maturity.

Despite the seasonally warm temperatures during the last week, many crops across Logan County benefited from a rain shower early in the week. Most of the county saw 1 to 2 inches of rain, which will undoubtedly help crop growth. Many corn fields are moving into the R5 “dent” stage, with not many lagging behind the leaders. Much the same can be said for soybeans, with most fields in the R5 seed stage.

Last weekend’s 3+ inches of rain gave a much-needed boost for crops across Logan County. While some areas may still exhibit signs of heat stress, most fields appear strong and healthy. Corn at the University Research Plot in Hartsburg and across much of the county is in at least the R3 “milk” stage, with some in the R4 “dough” stage. The same can be said of soybeans, with nearly all fields having pods at various stages of development. Cooler temperatures and more rain in the next week will undoubtedly be welcome.

Last week brought sporadic pop-up showers that benefited some fields needing a shot of rain to support growth and development in the reproductive stage. A few corn fields are still in the late V-stages, while nearly all have tasseled and ears are beginning to show. The same can be said of soybeans, with nearly all fields across the county at least in the R2 stage.

The growing season is entering a key phase, during which many fields and plants are transitioning into the reproductive stage of growth. Nearly all of the corn fields in the area have entered the R1 phase, with some likely further along. There are still some fields in the later V-stages, but they won’t be behind the rest for too long. Much the same story can be said of soybeans, with some more mature fields in the R1–R2 phase, while others are in the later V-stages. Rainfall has also been variable across the area over the last week. Some parts of the county received around an inch of rain, while others received a half-inch or less.

The high temperatures over the last week have caused many corn fields to grow at a rapid pace. There is hardly a corn field that isn’t knee-high—one week before the Fourth of July. At the University Research Plot in Hartsburg, IL, corn is at the V9–V10 stage, with other fields in the area at V7–V8. Soybeans have faced a tougher challenge with the high temps. While some fields are handling the heat well, many are showing signs of stress, including cupped leaves. There are no additional signs of insect or disease pressure yet, but continued high temperatures will likely lead to more issues.

Crop growth is starting to vary across Logan County. Corn around the county looks very healthy, with many fields well above knee-high. Growth stages range between V4 and V6. Soybean growth is more varied. Some fields look healthy and are in the V4-V6 stage. However, some fields are lagging, with some in the V2 or V3 stage. With beneficial rains on 6/18 and more hot temperatures on the way, it will be interesting to see how these fields progress over the next week.

Warm temperatures have been very welcome and have helped spur crop development. While there has not been much rain over the last week, there is still plenty of moisture deeper in the soil from previous rains. Some insects are starting to show themselves in corn and soybean fields, but there are no signs of significant damage yet.

This last week has seen very favorable conditions for crop growth across the area. The increase in temperatures has helped recently-planted fields begin to emerge. Much-needed rainfall arrived yesterday (6/4), filling many low-lying areas and ditches with water. Much of the corn and soybeans across the region are in the V3-V5 stages, with favorable conditions ahead likely to support plant growth.
