Fertilizer
All soils are not equal. Rich loams support the world's most productive agricultural regions, including swaths of the American Midwest. But in some parts of the Midwest, including areas in Missouri and Illinois, claypan soils dominate. And where claypans reign, problems for producers abound. New research from the University of…
There are both environmental and agronomic concerns surrounding the management of livestock manure. The major environmental concerns are: potential risk of nutrient accumulation in soil – particularly nitrogen (N) and phosphorus (P) – and risk of nutrient movement into surface or groundwater. Poor manure management can also cause accumulation of…
Industrial fertilizers help feed billions of people every year, but they remain beyond the reach of many of the world’s poorest farmers. Now, researchers have engineered microbes that, when added to soil, make fertilizer on demand, producing plants that grow 1.5 times larger than crops not exposed to the bugs…
Prairie farmers primarily use urea (46-0-0), anhydrous ammonia (82-0-0), or liquid urea-ammonium nitrate (UAN) (28-0-0) as their nitrogen (N) fertilizer sources. Nitrogen fertilizer can be lost due to volatilization, denitrification or leaching, depending on how the N is applied and the weather conditions after application. 
A popular fertilizer for farmers is urea, a nitrogen-rich organic compound found in human urine. Urea is water soluble and volatile, which means that irrigation or a heavy rains often sweeps it away in surface run-off or it escapes as a gas before it can be absorbed by plants.
Canadian growers are under increasing pressure to operate efficiently with the profound change in farming today. Larger operations with more acreage to cover, the pressure of lower crop prices and higher input costs, and demands for environmental efficiency mean every dollar and agronomic practice must be used as effectively as…
Wet weather last fall capped a challenging season for western Canada growers who had dealt with drought until excessive rains delayed harvest. These less-than-ideal conditions hindered fertilizer application, meaning growers may feel the need to rush 2017 applications.
Nitrogen inhibitors can dramatically improve productivity and injection is by far the best way to incorporate nitrogen into the soil while minimizing nitrogen loss.
Scientists at the Conneticut Agricultural Experiment Station are using nanoparticle technology to apply copper to the shoots of plants. Based on preliminary findings in the research, these nanoparticles are better at helping deliver the necessary nutrients to the plants and keep them healthy despite the presence of Fusarium in the…
by Dave Evensen April 2016 - Plant biologists at the University of Illinois have pinpointed the area of genomes within nitrogen-fixing bacteria in roots, called rhizobia, that's being altered when the plant they serve is exposed to nitrogen fertilizer.

Developed by plant breeders in Saskatchewan and Manitoba during the 1960s and 1970s to meet a growing demand for edible oil production in Canada, canola has become a major cash crop in Western Canada. It has been less attractive economically for eastern producers, primarily because so few crushing facilities are…
Oct. 29, 2015 - In their first year of large field-scale trials in Western Canada, nitrogen stabilizers N-Serve and eNtrench proved to secure more available nitrogen for plants and in many cases, contribute positively to yield. N-Serve and eNtrench, used with anhydrous ammonia and liquid fertilizer respectively, prevent the loss…
September 30, 2015 - Ontario is working to improve and maintain water quality in the Great Lakes by supporting the development and implementation of a nutrient stewardship program for farmers. As part of a recently signed Memorandum of Cooperation, Ontario will provide $50,000 to Fertilizer Canada and the Ontario Agri…
Oat is a competitive crop that is suited to central and northern Alberta growing conditions, but oat agronomic research has been lacking in Alberta in recent years. “When I found out about the high yield potential of oat, I was fascinated by its potential to be a high-value crop for…
