Fertilizer use fuelling climate-warming nitrous oxide emissions, study says

London | Reuters — Rising use of nitrogen-based fertilizers is driving up global emissions of nitrous oxide, a lesser-known greenhouse gas, complicating efforts to limit climate change, scientists reported in a study on Wednesday. Most of the focus in curbing climate-warming gas emissions has focused on the most abundant, carbon dioxide, and one of the […] Read more

New nitrogen stabilizer available in Canada

Anvol offers long-lasting protection from ammonia volatilization

Anvol, a new, patented, nitrogen stabilizer developed by Koch Agronomic Services, is now available in Canada. The product, which can be used with urea or UAN (urea ammonium nitrate) fertilizers, offers extended volatilization protection through a novel active ingredient called Duromide. The active ingredient was designed to provide longer-lasting protection from ammonia volatilization beyond the […] Read more


Three situations where an in-crop nitrogen application may be worthwhile

Q & A with an expert

Q: When should I consider an “in-crop” application of nitrogen? A: Under the arid environment of the Canadian Prairies, splitting nitrogen applications in annual crops (e.g. applying 70 per cent of the nitrogen at time of seeding and top dressing the balance during the vegetative stage) rarely provides an agronomic benefit over applying all the […] Read more

Today’s biggest issues in soil fertility

When to broadcast, shallow band, deep band and top dress

Rigas Karamanos, a senior agronomist with Koch Fertilizer Canada, is one of the leading Canadian experts in soil fertility today. After speaking at hundreds of producer conferences and research symposiums, Karamanos says there are four major topics that come up again and again at every discussion of agricultural soil fertility. Broadcasting, shallow banding, deep banding […] Read more


Finding the fit for premium fertilizer products

Good for reducing the environmental footprint, crop production and management

Enhanced efficiency fertilizer (EEF) products that provide a range of benefits in terms of crop production and management, as well as environmental benefits, are likely to play an increasingly important role in coming years of Western Canadian crop production, says Mario Tenuta, a University of Manitoba soil scientist. The products, with familiar brand names such […] Read more



Fall-applied nitrogen and nitrogen stabilizers

Keep your nitrogen in the soil where plants need it

Applying nitrogen fertilizer in the fall is an effective way to manage time and efficiency when spring comes. However, it can be hard to assess how much nitrogen is available in the root zone early in the season and what was lost to leaching and denitrification. Leaching is the loss of nitrates to the soil […] Read more

Les Henry: Anhydrous ammonia and the 4Rs

Time to bring back what should be the cheapest form of nitrogen fertilizer

Almost all farm press of late that talks about fertilizer use emphasizes the 4R concept. That means that we will take each nutrient and decide what is the “right” source to use, what is the “right” application rate, what is the “right” placement and what is the “right” time to apply that nutrient. The nutrient […] Read more


Get the most efficiency from your nitrogen

Generally, banding is the most efficient method for reducing nutrient loss

If you’re looking for a quick and easy guide to choosing the right placement for your nitrogen application, there isn’t one. Neither is there a one-size-fits-all strategy for timing or rate. There are, however, clear guidelines on how to improve nitrogen efficiency while limiting environmental impact. University of Manitoba soil science professor Don Flaten explains. […] Read more

The pros and cons of top dressing nitrogen

Q & A with Nutrien Ag Solutions

Q: What are the advantages and disadvantages of top dressing nitrogen? A: Top dressing nitrogen is one fertilizer option to help achieve yield goals. The advantages include increasing yield potential, increasing time efficiency and diffusing financial risk. Timing is key. The nitrogen needs to be applied early in the growing season and before a rain […] Read more
