Grain moisture content for safe storage.
Corn sold by spring                                  15.5 %
Corn stored 6 - 12 months                         14.0 %
Corn stored more than 12 months            13.0%
Soybean stored 6-12 months                    12.0%
Soybean stored more than 12 months       11.0%
Corn grain with moisture content of up to 22% can be stored up to 190 days - if it is truly cooled to 30 degrees F.   Aeration fans that are sized at 0.1 CFM per/bushel will take about 150 hours or 6-7 days to cool a bin of grain.
Nutrient content of baled stover. Baled stover/crop residue can remove the following amounts of phosphorus and potassium. These figures represent nutrient removal that is harvested immediately after grain harvest. See page 4/table 2 in PM 1688.
Soybean residue                                  P205                            K20
- per ton at 10% moisture                    5.0                               23.0
Corn stover
- per ton at 15% moisture                    5.0                               18.0
Dicamba update. The EPA has registered dicamba applications for dicamba tolerant soybean for 2 more years.  Changes include application timing restrictions to 45 days after planting/before the R1 stage and restrictions on early morning/late day applications. The interpretation of the 57 foot application setback to protect some broadleaf plant species is unknown at this time.  Bob Hartzler weighs in with this article. 
Crop Advantage Series 2019 .  Registration for the 2019 Crop Advantage Series will be open soon.  Meeting locations are January 8 in Storm Lake and January 15 at Okoboji.  Topics include N management in a wet season, grain market outlook, dicamba and soybean midge.
