  1. When considering adjusting your corn nitrogen program for dry weather conditions, consider how N gets to the root system for uptake. Mass flow is the primary mechanism for nitrogen (also sulfur, magnesium, and calcium). Mass flow is where nutrients in soil solution move toward the root as the plant takes up and transpires water through the crop canopy. Also, consider how dry weather affects the plant root system. Root growth will slow in dry soils, the situation we are now experiencing in the upper soil depths.

    The Ohio State University Extension – Hancock County office will be offering its Hot Topics in Grain Crops Series over three evenings in February and March at the Hancock County Agricultural Service Center, 7868 CR 140, Findlay, OH 45840. Each meeting will cover one specific crop – wheat, corn, and soybean. Local research results and a discussion on upcoming production issues will be presented at the meeting. There will also be a Question-and-Answer period to address any issue concerning that crop which was not part of the presentation.

  3. Fertilizer applicator certification began in 2014. The agricultural fertilizer applicator certificate is required by the Ohio Department of Agriculture when you apply fertilizer to more than 50 acres of agricultural production. Agricultural production is defined as grain, forage, and other cash crops grown primarily for sale. Both horticultural and agronomic crops are included under this law. There is no distinction between commercial and private fertilizer applicators: both certify or recertify in an identical way.

    Throughout this winter meeting season, fertilizer has been a hot topic. Generally, the discussion has been around nitrogen price and availability. Most of us have little to no influence on price or availability, but as a farmer, you decide your corn (and wheat) nitrogen rates, assuming you can get the nitrogen product you want. Your corn nitrogen rate could likely cost $100 per acre more in 2022 as compared to the year prior and nitrogen will probably surpass seed as the most expensive variable cost per acre this year.

    During this period of high prices and uncertain availability of phosphorus and potassium fertilizer, a few basic soil fertility concepts can help guide application decision-making. Fortunately, the work during 2014-2020 that led to the Tri-State Fertilizer Recommendation for Corn, Soybean, Wheat, and Alfalfa-2020 is current information we use. Here are a few key points from the Tri-States plus some other principles that may help.

    The profit margin outlook for corn, soybeans and wheat is relatively positive as planting season approaches. Prices of all three of our main commodity crops have moved higher since last summer and forward prices for this fall are currently at levels high enough to project positive returns for 2021 crop production. Recent increases in fertilizer prices have negatively affected projected returns. Higher crop insurance costs as well as moderately higher energy costs relative to last year will also add to overall costs for 2021.

  7.  An update to the Fertilizer Calculator for Ohio has been posted at https://go.osu.edu/ohiofertilitytool. The Fertilizer Calculator for Ohio (Version 2021) corrects an error in calculating whole field fertilizer cost and standardizes the width of field/subfield description fields across tool forms based on user feedback.

    The Ohio Department of Agriculture is rolling out the H2Ohio plan this month at eight meetings in the Maumee River Watershed. Farmers living in the following 14 northwest Ohio counties will be eligible to apply for funds at their local Soil and Water Conservation Districts (SWCD) starting this week: Allen, Auglaize, Defiance, Fulton, Hancock, Hardin, Henry, Lucas, Mercer, Paulding, Putnam, Van Wert, Williams, and Wood. Soil and water Conservation Districts will be the first contact for farmers interested in the available funding.
