As you can see, our field has lost that lush green
color since last Tuesday. Now, we see more yellowing. It is suppose
to do that. Our field is still in good shape. If it rains now will
that help our field? That's a good question. At this stage, a rain
would help but not to the same extent a rain the first week of
August would have helped. So, yes, it would help a little bit.
in our row are starting to turn yellow. That happens this time of
year as the days get shorter and nutrients in the leaves are
transported to the seeds in the pods. As this happens, chlorophyll
is lost and photosynthetic activity is reduced. But other leaf
pigments, such as the carotenoids still remain active which gives
the yellow coloring.
first plant looks like it has shrunk, doesn't it? Its leaves are
turning yellow. Eventually, these yellow leaves will fall off,
leaving only the pods. The leaves at the top look like skeletons
with all the insect feeding.
second plant is losing leaves too. You can see them on the ground.
The pods are still green, but there is a hint of yellowing. Mature
soybean seeds have a yellowish color.
