(Lakefield, Mn.)-- Unseasonably cold temperatures last week caused issues for some crops in southwest Minnesota. Jim Nesseth of Extended Ag Services in Lakefield says some soybean fields experienced some frost damage...Nesseth & Frost Damage01 

"Any of the low lying areas that had highier residue, that seemed to be where we had the most injury. And the no-till beans, you know, I'm a little concerned about some of them in those low lying areas. We've got some casualties there with some of the plants and we're kind of taking a wait and see attitude there to just see what we'll have for final stands once we get some re-growth going. But we're definitely looking pretty hard in a couple of those fields and I suspect we might have some re-plant in some of those areas. It's mainly the low lying areas and strangely enough, you know, where we've got conventional tillage, you know, close to some of those same areas, everything looks fine. So for some reason those cold air temps got trapped in that residue maybe a little bit too long and so we've got some injury."

Nesseth says soybean producers that did sustain damage should consider several things before deciding on whether or not to re-plant...Nesseth & Frost Damage02 

"You know maybe if it's just five, ten percent of the field, and if we have a half a stand or even maybe a third of a stand, we're probably going to be okay because that soybean is just a unique plant that can really compensate for lower populations and so, you know, you just kind of got to say is this a big enough area to mess with, you know, to tear up what plants might be good. But if you've got a pretty big area where you've got a low population, say, you know, 50,000 to 75,000 or less, then you might consider, you know, re-planting that particular area. And that's where you talk with your seed dealer and see what you've got for a re-plant policy and federal crop and if you've got the 20 percent rule or 20 acres, whatever is less, you know, check with them and see if you qualify under that 20 percent rule you'll be able to, you know, get money for re-plants."

Nesseth says any corn that was damaged will recover as the growing point was protected.
