What is 4R Nutrient Stewardship?

What is 4R Nutrient Stewardship?

Manitoba is not like other agriculture areas looking to implement 4R, the room heard during the latest 4R Nutrient Stewardship training workshop in Brandon Feb. 23. The four Rs (right nutrient source applied at the right rate at the right time in the right place) form the backbone of Fertilizer Canada’s campaign to balance environmental

The phosphorus conundrum: low soil levels meet Lake Winnipeg pressures

Experts weigh in on managing low phosphorus levels in soil, while minimizing water health impact

Manitoba is in a difficult position of simultaneously having too much phosphorus and not enough. Manitoba Agriculture crop nutrition specialist John Heard highlighted this contradiction recently during a recent presentation at a nutrient stewardship workshop, noting phosphorus buildup in the Lake Winnipeg watershed has been a source of long-standing tension between regulators and agriculture.

The benefits of a controlled traffic crop

Confining equipment traffic could pay production dividends

Ten years ago Adam Gurr was surfing the Internet one evening and came across an idea that would change the way he operates — controlled traffic farming. Just as the name sounds, it’s a farming system built around permanent wheel tracks in each field; the crop zones and traffic lanes are permanently separated. It leaves

Phosphate products vary, but fate the same

Over time, they all want to become plant-unavailable phosphate rock

All phosphate fertilizers might not be created equal — but in the end they all wind up that way. That was the message Don Flaten, a University of Manitoba soil science professor, shared with farmers last month during a session at Ag Days. That’s because it’s a highly reactive compound and over time, the very

Eight things to look for in your soil test report

When you understand your soil reports, you’re in a better position to develop fertilizer plans with your agronomist. All soil testing labs report the same basic information, but each lab has its own unique format. No matter what your report looks like, first, check the information at the top: your name, address, field name, etc.

Is strip tillage the new black for Manitoba farmers?

The answer is ‘maybe’ — and probably ‘yes’ for sandy soils, but no research has yet been done in clay soils, according to University of Manitoba graduate student, Patrick Walther whose master’s thesis focused on soybean response to different tillage treatments. Walther compared four tillage treatments in soybean crops — standard double disc, vertical till

There are no easy solutions to soil compaction 
but there are some strategies to help avoid it

For producers soil compaction probably feels like an unwinnable catch-22. They need to get out and perform field operations to grow crops, but each pass contributes to the creation of soil compaction that can seriously hinder productivity. Provincial land management specialist Marla Riekman told producers at the recent St. Jean Baptist Farm Days that there

Retention not needed for tile installation

Tile drainage can increase yields, but increased returns require carefully crunched numbers

Tile drainage installation is on the upswing in Manitoba, but producers need to take a hard look at their operations and evaluate beneficial management practices before making the plunge. “Addressing excess moisture is definitely a worthy pursuit,” Mitchell Timmerman told producers gathered for St. Jean Baptist Farm Days last week. “In this province, we know

More emphasis should be placed on soil health, MCDA speaker says

Cover crops, reduced tillage, crop and livestock diversity can all help reduce watershed challenges

We’ve all had those moments when we realize what we do most of the time matters more than what we attempt once in a while.

Nitrogen use is going to get a lot more sophisticated in the coming years.

High-tech fertilizers offer great promise

More expensive fertilizer likely cheap compared to future N20 pricing

The fertilizers farmers use will one day be manufactured from algae or hydrogen fuel, not natural gas, and they’ll be ‘SMARTer’ too, said a speaker at St. Jean Farm Days last week. These will be long-lasting sensor-based nano fertilizers, not likely to be nearly as easy to handle as current products, and which may reside
