This Week’s Agronomy: Soybean Flipping and more….

This Week’s Agronomy.

Have you ever been driving by a field to notice the crops are looking thirsty? Whether it be corn rolling or soybean flipping, have you asked yourself why this is?

In soybeans, the crop is able to sense intense heat and utilizes petiole flipping to reduce the surface area of the leaves exposed to the sun for active photosynthesis. While this is good for water use, it is bad for yield, as photosynthesis is slowed! In corn, bulliform cells are responsible for the rolling phenomenon shown in hot, dry conditions. These cells lose turgor pressure as water content decreases in the leaves, causing a curl of the leaf on the surface that we see. After water is able to be taken up again by the crop, the leaves water content increases, and as such pressure increases, causing the leaves to extend back to their original size.

A note from our staff:  Many infestations of Western Bean Cutworm have been reported popping up in fields in Central NE. With many tassels popping and ears soon to develop, it will be key to your yields making sure those infestations are taken care of. 

You can learn more about these conditions below, or by contacting a CropMetrics Support Specialist here.
