More Active Fall Weather Pattern Ahead

By Jim Noel, NOAA

A more active weather pattern is ahead. We expect a weak to moderate storm with some rainfall every 3 to 4 days over the next few weeks.

For the week of Oct. 22, expect slightly above normal temperatures by a degree or two and rainfall between 0.25-0.75 inches on average. There could be some scattered freezing temperatures in the north and west sections of Ohio especially come Saturday morning.

For the last week of October, there should be early to mid week rainfall with another 0.25-1.00 inches followed by a surge of cold weather and the real possibility of the first widespread freeze toward Halloween.

The outlook for November is above normal temperatures after a cold start to the month and rainfall normal to above normal. The early trends suggest a turn to a wetter late winter and spring of 2020 but we will need to simply monitor that.

The next two weeks rainfall totals will generally range from 0.50 to 2 inches across the state.

October 2019 – Weather Prediction

By: Jim Noel, National Weather Service. Previously published by OSU Extension CORN Newsletter

After another hot week (until late this week), a cool down to normal temperatures is expected starting either Oct. 3 or 4 that will last through Oct. 15. Temperatures are expected to return to above normal (but no where near current levels) from Oct. 15-31.

Rainfall will be above normal in northern Ohio this week. The week of Oct. 7 will be normal or below normal but confidence is next week’s rainfall pattern is low to moderate. Above normal rainfall is in the outlook for the second half of October which could slow harvest after Oct. 15. Continue reading

Drought and Heat Stress

By: Peter Thomison, OSU Extension

One of the corn production scenarios agronomists least like is an exceptionally wet spring followed by a hotter and drier than normal July and August. The spring of 2019 was one the wettest on records throughout much of the state and now, as the dry weather that started in July persists, such a scenario seems to be a possibility in many Ohio corn fields. A combination of warm temperatures and inadequate rainfall is beginning to stress corn fields across Ohio. Continue reading

Average Fall Freeze Dates for Corn Considerations

By: Aaron Wilson, OSU Extension Climate Specialist and Sam Custer, OSU Extension Darke County

In last week’s C.O.R.N. newsletter, Peter Thomison provided useful information on tools available for switching corn hybrids (https://agcrops.osu.edu/newsletter/corn-newsletter/2019-15/more-switching-corn-hybrid-maturities). As Dr. Thomison points out, Dr. Bob Nielsen at Purdue University wrote an article describing the U2U Corn GDD Tool, available from the Midwest Regional Climate Center (https://mrcc.illinois.edu/U2U/gdd/), with caveats to keep in mind as one is making their decisions. Specifically, users are encouraged to modify their black layer GDDs within the tool in order to reflect a more accurate assessment of days to maturity.

Wetter Pattern than Normal will Continue into March…and Possibly April

By: Jim Noel, National Weather Service
Previously published in OSU Extension C.O.R.N. Newsletter

Not a lot of great news in the short-term. The wet pattern so far this year is likely to persist into March as an active weather pattern from the Pacific Ocean moves across the U.S.

In addition, the temperature gradient is amplified more than normal this late winter into early spring meaning colder north and warmer south. This will help fuel the storms and keep things active.

The outlook for March calls for temperatures near or slightly below normal with precipitation above normal.  Continue reading

Climate Change Gets Local

By Emily Unglesbee
DTN Staff Reporter, Previously published by DTN

LONDON, Ohio (DTN) — At 6 feet, 8 inches tall, with a bushy, orange beard, Aaron Wilson towers very visibly above the crowds at Ohio State University’s Farm Science Review.

But it’s what he’s talking about that really makes him stand out at the annual farm trade show.

In addition to OSU Extension, Wilson works at the Byrd Polar & Climate Research Center, studying the effects of climate change, an often controversial and misunderstood topic in agriculture. Continue reading

Ponding and Corn

By Peter Thomison and Alexander Lindsey, Ohio State University Extension

Persistent rains during the past two weeks have resulted in ponding and saturated soils in many Ohio corn fields and led to questions concerning what impact these conditions will have on corn performance.

The extent to which ponding injures corn is determined by several factors including: (1) plant stage of development when ponding occurs, (2) duration of ponding and (3) air/soil temperatures. Continue reading

Hybrid Switching Decisions

By: Dave Huff, NuTech Seed Agronomist, Eastern Product Specialist
Previously on Ohio Ag Net

With a late start for some and corn fields not yet planted throughout the region, growers are asking, “Do I need to be switching to earlier maturing corn varieties?” and “Should I replant problem fields?”

It seems like each year I need to address these questions. We learned in the past that corn requires fewer Growing Degree Units (GDUs) to mature when planted after May 1 than listed in product brochures. From my own research trials and University trial data, we can expect corn planted in our region to require on average around 6.8 fewer GDUs to mature for every day of delay beyond May 1. Another way to interpret this is that it would require approximately 200 fewer GDUs from May 1 planting versus June 1 planting to reach black layer. Continue reading

I-80 Planting Tour: Ohio (Henry County)

By: Betsy Jibben, AgDay Reporter

Cold temperatures and snow are keeping farmers out of the field in northwest Ohio. Some farmers have reported both rain and snow over the weekend.

The U.S. Department of Agriculture (USDA) released its weekly crop progress report showing no corn is planted in the state, which is a common threat across Interstate 80.

AgDay national reporter Betsy Jibben talks with Eric Klein, a farmer from Malinta, Ohio; Nate Like, a farmer from Hamler, Ohio; and Rex Williamson, an agent with Williamson Insurance Agency in Payne, Ohio.

Changing climate highlighted at Conservation Tillage and Technology Conference

By: Matt Reese, Ohio Ag Net

Increased rainfall in larger doses and warming temperatures in the future are likely, building on trends that have already been seen in Ohio.

The first day of the Conservation Tillage and Technology Conference included many presentations including nutrient management, crop production, water quality, technology and innovation during the event at Ohio Northern University in Ada. The role of the changing climate cannot be ignored in agriculture’s ongoing challenges with nutrient management and water quality.
