Resistance Management

We have been dealing with the effects of herbicide resistance in agriculture for many years now. In fact, the first case of herbicide resistance in Ontario dates back 60 years to 1957. While this is certainly not a new problem, resistance management has been thrust back into the spotlight in recent times due to the prolipheration of both glyphosate resistant weeds, and multiple chemistry resistant weeds.

 

Combating Compaction

Compaction is a real problem on most farms today due to the significant increase in equipment size and weight over the last 50 years. Often in our hurry to get the job done we can’t or don’t stop to wait for ideal soil conditions or think about the consequences of tire pressure or wheel load.  Soil compaction causes significant yield loss.  As the chart below depicts yield loss due to compaction can be up to 15% in the first year following the compacting event with losses continuing for many years even without further compaction occurring.  Repeated surface compaction causes a 20% yield reduction annually even with tillage.

 

pH: The Last Thing We Should Let Slip

We are often asked: Why spread Lime?  And the answer is that when soil pH is too acidic, lime is the best way to bring soil pH into optimum range.  Getting pH into optimum range is very important because soil pH regulates the natural nutrient availability in the soil.
