Phosphorus fertilizer rates have, pretty generally, lagged crop removal for some time. As crops remove the soluble phosphorus in the soil, the soil’s large reserve of less soluble forms will transfer some more phosphorus into the available “labile” pool. However, this labile pool may be losing its ability to keep up, resulting in a “hidden hunger” for phosphate in many… -
Canola has a high demand for sulphur. Because of high sulphur variability across most fields, the common recommendation is to apply 10-15 lb./ac. of sulphur when soil test results show adequate levels and 20-25 lb./ac., or more, when tests show deficient levels. Read more for product options and when to use them… -
As part of UCC 2015, the CCC agronomy team is looking for 12-15 growers from across the Prairies to test boron in field-scale trials in 2015…

Stephen Strelkov with the University of Alberta tested soil samples from 27 fields in Alberta that were seeded to resistant varieties in 2014 and showed more than expected levels of gall formation. Of those 27 fields, 15 have clubroot pathotypes that suggest the clubroot in those fields had overcome the resistance trait…

Growers sometimes prefer earlier maturing canola varieties given their season zone or if spring seeding is later than expected. Here is a list of all NAMED varieties supported for registration at WCC/RRC since 2009 that have maturity of at least 1.0 day earlier than the checks. If this list is missing shorter-season varieties currently on the market, please email Jay… -
A Canola Watch reader asks: “I am interested to find out how many acres of continuous canola are actually in the Peace compared to other areas.” Leander Campbell from Agriculture and Agri-Food Canada provided four maps, including this one… -
The Canola Council of Canada launches a new agronomy video on the value of strong stand establishment. Click the image above. In celebration of International Year of Soils 2015, the Canola Council of Canada (CCC) agronomy team spoke this week with the University of Manitoba’s Canada research chair in applied soil ecology, Mario Tenuta. His answers to a couple of…

The CCC agronomy team asked Mario Tenuta, the University of Manitoba’s Canada research chair in applied soil ecology, if preserving soil health really matters, or can soil degradation be corrected simply by adding more fertilizer. His answer: “If growers ignore soil health, input costs will go up. Increased inputs can compensate and keep up with soil degradation for quite a…
