Soil acidity is an issue that’s gaining attention in the Northern Plains, especially in areas where no-till practices have been paired with high surface-applied nitrogen rates. “They’re seeing this advancing a lot faster in parts of North Dakota and Montana, under traditional zero till conditions where they broadcast urea fertilizer. They find they’re acidifying the… Read More

Managing nitrogen fertilizer is a balancing of economic considerations, yield goals, and environmental implications. With both increased fertilizer prices and scrutiny on N fertilizer emissions, this episode of The Agronomists tackles the loss pathways and management tools required to minimize them. Our experts for this conversation are John Heard of Manitoba Agriculture, Peter Johnson of… Read More

Thanks for joining us and making RealAg Radio a part of your day. Join RealAgriculture’s Kelvin Heppner, as he talks with Marie-Claude Bibeau, Minister of Agriculture and Agri-Food, on the nitrogen fertilizer emissions policy, John Heard of Manitoba Agriculture on what research shows about different practices and products that reduce emissions from fertilizer, and also with… Read More

From a crop nutrition perspective, nitrogen losses as N2O or nitrous oxide pale in comparison to what’s lost in N2 form, but N2O has a much greater impact on the total greenhouse gas emissions from fertilizer. As part of this Wheat School episode filmed at Manitoba Crop Diagnostic School, Manitoba Agriculture’s John Heard shares a… Read More

Here’s to hoping everyone had a great Easter weekend! We are excited to be back with another episode of The Agronomists. We’re hitting the ground running with this week’s topic: nitrogen management. More specifically, this episode is focused on managing N losses and products that potentially help reduce some of those losses. This week’s panel… Read More

When it comes to applying nitrogen fertilizer, agronomists have to help determine the right rate, right placement, the right time, and the rate form of N to protect the environment and feed the crop. The backdrop to those decisions include the farm setup, soil test results, yield goals, and product availability. There’s also that key… Read More

Welcome to Agronomic Monday, packed to the rafters with content. On today’s edition of RealAg Radio, you’ll hear: John Heard, soil fertility specialist with Manitoba Agriculture and Resource Development, on the risks of growing soybeans on fields with excess nitrates; Kim Brown-Livingston, weed specialist with Manitoba Agriculture and Resource Development, on the discovery of palmer… Read More

The practice of split-applying nitrogen through the growing season has been increasing throughout U.S. midwest corn states and in Eastern Canada. In Western Canada, about 20 percent of corn growers in Manitoba have adopted the in-season practice, according to newly-released results of a survey conducted by the Manitoba Corn Growers. In this episode of RealAgriculture… Read More

Excess water after heavy rains in parts of Western Canada is not only impairing plant growth through oxygen deficiency, but it’s also causing significant nitrogen losses. As John Heard, soil fertility specialist with Manitoba Agriculture, explains in this video, N losses depend on soil type, with rain causing leaching in sandier soils and more denitrification… Read More

A science textbook will tell you the intense energy surrounding a lightning bolt causes a reaction between oxygen and nitrogen in the atmosphere that results in rain depositing nitric acid on the soil, where it becomes a usable form of nitrogen fertilizer for plants. On Twitter and in coffee shops, farmers sometimes give lightning credit for a field “greening up” after… Read More
