STEPHANIE PORTER UPDATES
Corn pollination is taking place. Soybeans will be approaching R3 (pod set) soon. Both corn and soybeans will be at the correct growth stage for fungicide and insecticide in about a week. There appears to be a lot of waterhemp escapes. Also saw minor corn snap and lodging.
This field has now shown yellowing or K deficiency in large areas for this year and two years ago in corn. Very, dry which only enhances the K deficiency symptoms. No other fields in the area showing symptoms. No spring N was applied at or near planting. We plan to investigate further.
Corn will reach tassel in 1 to 2 weeks. Soybeans will reach R3 in 1 to 2 weeks. Japanese beetles are moving in on field edges. Post herbicide applications have taken place in soybeans.
Corn is starting to appear stressed, with K deficiency symptoms due to lack of rain. Early planted soybeans are starting to bloom. Growth of both corn and soybeans is stunted. Some bacterial blight on lower leaves is of R1.
Conditions appear very, dry with some moisture still in the ground for recent replanted areas. Irrigation was running on corn. Crops have not quite show signs of drought stress yet but are close.
Some soybeans are showing signs of herbicide injury. Weeds are just starting to emerge. There was some minor bean leaf beetle feeding with a few plants showing signs of Phytopthora root rot.
This field was replanted into the original stand because most of the field was only 50,000 plants per acre after planting early, saturated soils, and then hail. Several weeds such as waterhemp and ivyleaf morning glory are coming on strong. Post herbicide will be needed soon.
Early planted corn is now at V5/V6, while later planted corn is at V3. Fields are clean for the most part. No signs of insects or disease.
The stands of soybeans appeared adequate for 30 inch rows. No signs of pests or other stress.
Stand counts were taken and were really good on both corn and soybeans. There were a few patches of cereal rye that did not completely die at termination. After further inspection, we found that the seeding depth of the corn was 1 1/2 inches, which is a much shallower depth than planned.
