SYNOPSIS

With adequate moisture, temperatures and sunshine….the crops are moving along at a good pace. Growth stages in both soybeans and corn are varied all over the countryside. Your fields may require very different approaches based on crop stage and field situation. It may be worth looking at extra Nitrogen for corn fields with excess rainfall. Another Pre-emerge herbicide added to your post application in corn or soybeans.

WHICH OF THE FOLLOWING BEST DESCRIBES CURRENT CONDITIONS IN THIS COUNTY?
Mildly Wet (soil is wetter than normal, local vegetation is healthy)
WEATHER

frequent rains and in some cases locally heavy rains have made significant differences around the area.

PRECIPITATION

Plentiful rainfall. According to my Fieldview account we are approaching 6″ of rain since planting the first date of the soybean trial. The 30 year average from the planting date to now is about 3″

FIELD/SOIL CONDITIONS

Soils are dry on top and are fit to travel across. There are some ponds that may still be a bit too wet to work with, but it really depends on the field, rain and drainage.

FIELD ACTIVITIES

Still seeing planters around, likely spotting in bare areas from ponding water. Most of the activity is transitioning to post herbicide applications and side dressing corn.

SOYBEAN GROWTH STAGE

VC-V6/R1

CORN GROWTH STAGE

V2-V7

WHEAT GROWTH STAGE

NA

INSECTS

No major issues found or reported to my knowledge. Local fields may vary based on management practices and crop stage.

WEEDS

Just like the crops….adequate moisture and good growing conditions is allowing for weeds to thrive as well. The pre emergent herbicides have likely ran their course. Depending on crop stage it may be well worth it to add more pre to a post application.

DISEASES

With the wet weather, conditions seem favorable for diseases. I have not seen any first hand, but I would not be surprised to start seeing reports. Especially as some of the seed treatments are wearing out.

ABIOTIC ISSUES

Ponding issues from water standing.

OTHER

With the heavier than normal rains in some areas, I think it would be worth looking at supplemental nitrogen. Water can leach nitrogen OR in water logged soils, denitrification can also happen. What we do not want to happen is to react to N deficient corn. Damage has been done at that point. Around the V5 stage of corn is when ears are forming and the foundation is being set for yield levels.
