Crop Report – June 17

Alex Yost running our 360 SOIL SCAN doing a nitrate test in the field.

This week has shifted into sidedress season at the coop, with the warm weather of last weekend and the cool down mid-week the corn has begun to add some height and growth stages. The majority of the corn in the area is beginning to regain some green color, but after taking some early season nitrate tests we are seeing that it may be short lived for some fields. This year, the fields that are showing signs of nitrogen deficiency already, which means they may have lost the majority of their nitrogen from the wet weather events. A nice cheap and easy tool for checking the nitrate levels of your fields is through our 360 SOIL SCAN, we can pull soil nitrate tests and have same day results for your fields to get an accurate gauge of what is left, and what you may still need to put down. If you are seeing other signs of deficiency in your fields, our plant tissue tests may be a beneficial tool. Talk to your agronomist or YieldPoint specialist to schedule these.  

The soybeans across the area have begun to add many new leaves and some height, the wetter fields are still stressed from the prior rains though. This stretch of dry weather is helping those areas catch up to the rest. Water hemp is beginning to poke through on some pre emerge sprayed fields this week, so keep an eye on the fields with past history of issues. Remember catching the water hemp plants young is the easiest way to rid your fields of the issues they may cause if they get big. If you are seeing dark brown spots on the soybean leaves on the bottom of the plant, this is a common disease after heavy rainfall events from splashing dirt. Septoria Leaf Spot, or Brown Spot of Soybean is the name of this disease and yield limitations are minimal as long as it stays in the lower canopy.  

The alfalfa has been progressing nicely with the timely rains and heat of this early summer and is keeping ahead of the insects for the most part. This being said, watch late cut fields and new seedings this week, as most damaging insects will flock to these fields once the early cut plants add too much height. Also watch fields that may be excessively dry or stunted. After the next cutting, we will need to intensively watch fields for leafhoppers, because the warm weather and southern winds have brought a good population of them north already.
