This photo shows Earl Christiansen at the Shaunavon site in 2006. Earl and I had gone to check out the site after 24 years. Farmer Bruce Poppy left the patch of grass as we suggested and left our nest of piezometers. The “deep” 53-foot piezometer has since started to flow but not enough to cause flooding, so it is OK. In this case “deep” was 53 feet.

Les Henry: A look at soil nitrate-nitrogen

Is there enough residual nitrate-nitrogen in the soil to feed 2022 crops?

The drought of 2021 and the poor crops as a result have left us wondering what residual nitrate-nitrogen might be present in the soil to feed the 2022 crops. Nitrate in the environment The first thing we must realize is nitrate in the environment is, for the most part, a function of human activity in […] Read more

How to develop nitrogen fertilizer recommendations

Each field and crop deserves thought and attention

In last December’s Grainews, I discussed interpretation of soil test reports. In this column, I will discuss developing nitrogen (N) recommendations. In the next several columns, I will discuss developing fertilizer recommendations for phosphorus (P), potassium (K), sulphur (S) and other nutrients. Western Canadian farmers spend more money on nitrogen fertilizer than all other nutrients […] Read more

How to manage fertility for pulses after a dry year

Soil test and understand how nitrogen fixation can be affected

When it comes to fertility planning for pulse crops, western Canadian farmers might want to consider soil testing this spring. That’s because there’ll likely be higher amounts of residual nitrogen left over and greater variability in nutrient levels due to last year’s drought, which curtailed crop uptake and nutrient utilization in many fields. “It’s important, […] Read more
