#NField Reports - June 22-26, 2020
This week, Megan Taylor shares tips for avoiding power lines while spraying as well as what to do if you have an incident, Steve Melvin talks about irrigating vegetative corn, and Kat Caswell talks about hairy vetch for those new to cover crops.
#Nfield Observations teamed up with @NPPDnews to talk safety around power lines!— Megan Taylor (@CropTalkMegan) June 25, 2020
⚡️Remember maintain a minimum 10-foot clearance from lines, electricity can arc through the air between the line and the grounded equipment.

Soybeans Feeling Yellow? #NField Observations looks at #IDC or Iron Deficiency Chlorosis and some ways to avoid it. @UNL_CropWatch #NebExt— Aaron Nygren (@ColfaxCountyExt) June 17, 2020
pH, soil water, soil nitrates make IDC worse
Chelated iron, variety selection, companion crops, seeding rate can help pic.twitter.com/E8jRBXaHHV
Seeing sporadic lime green/bleached #corn? #Nfield is checking out rapid growth syndrome or twisted whorl corn in NE Nebraska today!— Megan Taylor (@CropTalkMegan) June 18, 2020
RGS can appear V5 up to V12
3 to 7 days to unroll and green up

The hot, dry weather has put a damper on wheat disease spread, so let's do some #Nfield observations of what stage field peas are at (didn't find much disease or insect pressure here either). #Nebext pic.twitter.com/FXstE0IMzt— Kat Caswell (@KECCrops) June 17, 2020
#Nfield observations, whew its hot and windy today in Nebraska! What do these conditions mean for your #alfalfa and regrowth? @UNL_CropWatch #nebext— Megan Taylor (@CropTalkMegan) June 16, 2020

#Nfield Observations out in the fields before the storm, seeing a lot of #waterhemp, be sure to scout what weed pressure looks like on your acres.— Megan Taylor (@CropTalkMegan) June 9, 2020
Remember the key to ID Palmer vs. Waterhemp is the petiole, Palmer longer than leaf, Waterhemp shorter!@UNL_CropWatch #nebext pic.twitter.com/FkVGOrcwdw
