Unlike soil tests for phosphorus, potash or nitrogen, there is no current reliable soil test for sulphur in Ontario.

Why we need a sulphur test for eastern soils

Producers in the West routinely test their soils for sulphur. Soon the East may too

Reading Time: 5 minutes For much of the past decade, a growing list of organizations have tried to build a link between soil health and soil test levels. They’ve wanted to raise awareness of the current status of soils on farms across Ontario, sometimes by pointing the way to higher productivity and profitability, and other times with a focus […] Read more

The long-term strategy for P management relies on building, maintaining or depleting soil P, based on soil test P concentration. Medium (M) would be around 15 ppm. High (H) would be around 30 ppm.

Phosphorus 101: The basic BMPs

Here are the basic best management practices for phosphorus fertilizer

Reading Time: 3 minutes Soil tests The Olsen (bicarb) test is effective across a wide range of soils, including the high pH calcareous soils common in Manitoba and Saskatchewan, while the Bray test is effective only in neutral to lower pH non-calcareous soils, as are found in parts of Alberta and Saskatchewan. Kelowna and modified Kelowna tests are also […] Read more


Cupping of soybean leaves is a clearly visible symptom of off-target movement of dicamba that resulted from inversion.

Soybeans, dicamba and you

New challenges are arising with new herbicide-resistant technologies and product blends

Reading Time: 4 minutes When new transgenic and herbicide-tolerant technologies arrive, they come with learning curves, some steeper than others. For Bt corn hybrids, for example, the curve was relatively flat, even if there had to be some serious thinking that about refuge planting. And in glyphosate- and glufosinate-tolerant soybean varieties, there may have been initial concerns about having […] Read more

Sulphur-deficient plants appear paler (foreground) than those with adequate S.

Sulphur gets hot

The nutrient’s use is definitely trending up, and there’s still more room for growth

Reading Time: 5 minutes It’s a question that’s asked of a lot of nutrients in soils across Eastern Can­ada: Is there enough in my soil, or isn’t there? Discussions surrounding deficiencies and field levels typically target macronutrients like potash and phosphorus, or even other nutrients like nitrogen, or the micronutrients magnesium, manganese, boron, zinc or copper. But sulphur sits […] Read more


The Wintex 2000 is popular in Western Canada but is now being replaced by Wintex 3000 units.

Advanced soil sampling

It’s time to get excited about soil testing again… seriously!

Reading Time: 6 minutes In many ways, a soil test represents an aspect of farming that is necessary yet unfairly and inaccurately viewed with about as much anticipation as filing an income tax return. Despite the fact that soil tests provide invaluable information and a potential road map for adding value to future crop plans, there isn’t an overall […] Read more

Manitoba Agriculture soil specialist is working with a Canadian Foodgrains Bank conservation agriculture (CA) project in Kenya. The hand at top is holding soil from a CA field while the soil in hand at bottom is from a non-CA field immediately adjacent. The CA field has been in CA practice for three years, or six cropping cycles. The CA soil has more aggregation and is darker, indicating more organic matter.

New tests get closer to helping producers build soil health

Reading Time: 5 minutes What’s involved in a soil health assessment? And what makes soil “healthy” in the first place? Researchers at the Chinook Applied Research Association (CARA) in Oyen, Alta., are keen to answer these questions for western Canadian producers. The association is launching a new lab in the CARA facilities that will collect and analyze soil samples […] Read more


Microbial activity in a healthy soil is evident by its aggregated structure, as well as the presence of root channels and worm holes.

A healthier soil test

Is it time to start investing in the Solvita soil test for your farm?

Reading Time: 6 minutes It’s a curious trend. “Soil health” is one of the great buzz phrases of modern agriculture. Admittedly, it’s just words to some, yet for a dedicated and growing number of producers, it’s a primary goal. Yet if you ask the average farmer if they test their soil once every three years, as recommended, the answer […] Read more

To sample, or not to sample (soil). Who’s right?

To sample, or not to sample (soil). Who’s right?

Some of your neighbours have stopped soil sampling. Others are sampling more than ever.

Reading Time: 5 minutes In any year, at most 10 per cent of the fields are soil sampled,” says Tom Jensen, a director in the North American program of the International Plant Nutrition Institute. “Some people say 20 per cent of farmers do some soil testing, but they may only do it every couple to three years.” Farm consolidation […] Read more
