Digging deep for soil phosphorus

Field Notes: P movement is limited in soil, particularly under dry soil conditions

As my PhD work conducted over the past four years reaches its completion, I’ve reflected on my master’s work more in the last few months than I’ve done since completing it nine years ago. In this column, I would like to highlight a few take-home messages from that work. The 4Rs of phosphorus (P) stewardship […] Read more

The role of enhanced efficiency fertilizers in nitrogen fertilization 

Crop Nutrition: Maximum crop production cannot be achieved with fertilizers and amendments alone

When trying to enhance crop production with fertilizer, we first need to answer the following questions: What crop yields are possible and what fertility and moisture are required to get there?   Crops exhibit different water use efficiency in every part of the Prairies. Water use efficiency is also weather dependent and when combined with best […] Read more

Rethinking nitrogen efficiency

Tracking nitrogen with stable isotopes offers surprising insights into fertilizer uptake, loss, and management strategies

Understanding how much nitrogen actually gets taken up by plants is key to improving efficiency—both for profitability and sustainability.

Cutting N on oats can pay off, if it’s drier

Potential gain in net revenue must be weighed against opportunity cost

Glacier FarmMedia — It’s possible to make more money from oats by reducing fertilizer rates, according to research done at four sites in Saskatchewan. But like most things in farming, a lot depends on the weather. Less nitrogen equalled more profits in trials done in 2023 because it was a dry growing season. “When you […] Read more
