The spray drone business started booming in Western Ohio suddenly this season and there are many new things to learn with this technology for researchers, extension, and producers.

Application of Manure to Double Crop Soybeans to Encourage Emergence

Wheat harvest is mostly done in the state and some farmers are planting double-crop soybeans. The summer manure application window following wheat harvest is typically the 2nd largest application window each year.

Wheat Harvest Date Reminders

While many areas of Ohio have already successfully harvested wheat, there are fields that still need to be harvested. With rainfall this week, harvest may be delayed.

Soybean Progress and Flowering Growth Stage

Currently, most soybean fields in Ohio are at the flowering growth stage (R1-R2).

Nutrient Value of Wheat Straw

Before removing the straw from the field, it’s important farmers understand the nutrient value. This is especially important now with high N, P, and K fertilizer prices.

Double-Crop Soybean Weed Management

It’s been a tough summer in parts of Ohio to do anything on a timely schedule and there are some weedy fields.  The best advice we have for big weeds in full-season soybeans is to increase rates and the complexity of POST herbicide applications, while still adhering to cutoffs for the

Estimated and Soil Test Methods to Determine Supplemental N need after Flooding

Determining the amount of supplemental nitrogen, if any, that is needed after saturated soil conditions is a difficult question to answer.

Managing Corn and Nitrogen with Water Excess Conditions

Excess water challenges plant growth and fitness in farming systems. Depending on the geography, dramatic fluctuations and extremes in weather patterns have been experienced in Ohio, the US, and other parts of the world (e.g., droughts, floods).

Summer Crop Insects – What to Watch For

Almost every field season has its particular insect problems and surprising‘ gotcha’ moments (we’re looking at you, fall armyworm).  But there is a seasonality to our common insect pests in agriculture, and this article outlines a few of the things to look out for in the remaini

It’s Getting Hot in Here

The 2022 crop has already seen its fair share of stress. But with the forecast of a flash drought and much higher than normal June temperatures, we will be seeing some extra stress that we may normally anticipate for later in the growing season.

Time to Start Scouting for Potato Leafhoppers in Alfalfa

We are receiving reports of near or at-threshold levels of potato leafhopper in alfalfa.  As second-cut alfalfa grows, farmers should scout for resurging numbers in their fields.  Younger alfalfa is more susceptible to damage at lower leafhopper numbers.

Corn Growth and Development: Crop Staging

One of the bottom-line activities in growing crops should be understanding and keeping track of crop growth and development. Crop growth is related to the increase in size.

Crops Under Water – Crop Stage is Critical for Recovery

Large rain events seem to be trending this year in many parts of Ohio, especially in Northwest Ohio where 3-5 inches of rain fell in 24-48 hrs. This can lead to standing water (flood) conditions or waterlogged soils (the root system is saturated).

Double Crop Soybean Management Considerations for 2022

Wheat harvest is just around the corner, and it’s time to consider double-crop soybean production management. For double-crop soybean to be successful, you need adequate time and moisture for the production of the soybean crop.

Double Crop Soybean Production in Northern Ohio

In northern Ohio, double-crop soybean production after wheat harvest needs to be carefully considered.

Wet Weather then a Planting Window

April was a challenging month. It was a cold month with most of Ohio -1F to -3F below normal for temperatures. We saw late freezes and snow events. Because of the cold, precipitation was generally around or slightly below normal in the 60-120% of normal range.
