Alfalfa – It has been challenging to find a time between rains to cut and bale alfalfa in the area. Fall planted alfalfa can be harvested at first bloom or when regrowth can be found at the crown. Spring planted alfalfa should be left until at least mid-bloom to allow some root reserves to build before taking the cutting. Tissue samples can be pulled after 5” regrowth and may identify some unknown micronutrient deficiencies.

Wheat – Wheat is flowering throughout the area. Fungicides were applied to many fields in the last 10 days to help with plant health and protect against rust infestations. Be sure to apply fungicide at the appropriate time to avoid Pre-Harvest Interval concerns and get the most protection from the product.

Corn – Corn is still a bit slow to come up, with some of the area still struggling to get any planted. Some earlier planted corn is showing some Iron Chlorosis due to cool, damp conditions.  There is still time to get corn in. Considering the amount of rain we have had, evaluate the potential nutrient loss that may have occurred and make plans to apply additional nutrients as necessary.

Soybeans – Soybeans are slow to emerge. Last week’s warmer weather did increase the soil temperatures, but this cool, wet spell may cool it back off some. Be sure to take stand counts as early as possible to identify whether replanting is necessary.

Burndown Treatments – With recent rains, fallow or open ground is starting to green up. Starting to see a lot of crabgrass and a few pigweeds emerging. Weed control is most effective when weeds are 4” or smaller, so monitor these acres closely and plan to treat accordingly.
