SYNOPSIS

Corn, soybeans, and wheat are all quickly progressing. Some early-planted corn crops are already waist high, greatly preceding the old “knee high by the 4th of July” saying. Recent rainfall events as well as tornadic winds have resulted in lodged corn in some fields. Precipitation that came along with the storms was needed in these counties but came so quickly that some fields were ponding again. Wheat fields have turned and will be harvested soon.

WHICH OF THE FOLLOWING BEST DESCRIBES CURRENT CONDITIONS IN THIS COUNTY?
Moderately Wet (soil is damp, standing water may be present in low areas, water bodies are full)
IF CONDITIONS ARE ON THE DRY END, WHICH OF THE FOLLOWING US DROUGHT MONITOR CATEGORIES BEST FIT CURRENT CONDITIONS
Near Normal (Dnada)
WEATHER

High winds tested the corn on the 10th and 11th. In some fields, these intense winds have resulted in corn fields lodging.

PRECIPITATION

Many fields in the area got somewhere between 2-5″ of precipitation with the storms that rolled through the central part of the state on Wednesday the 10th and Thursday the 11th.

FIELD/SOIL CONDITIONS

Most fields quickly soaked up the rain that was received on the 10th, but for some areas, receiving an additional 1-2″ on the 11th resulted in ponding in low lying areas of the field.

SOYBEAN GROWTH STAGE

V3-V5

CORN GROWTH STAGE

WEEDS
