The key with fertility decisions is to apply all of the 4 Rs — right fertilizer source at the right rate, at the right time and in the right place.……

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.

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 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… -
The CCC agronomy team asked Mario Tenuta, the University of Manitoba’s Canada research chair in applied soil ecology, if continuous canola can actually create a canola-friendly soil environment. His answer: “There are several examples where continuous cropping of other crops have created a soil microbial population that can keep down soil-borne diseases. Can the same happen with canola? Likely. However,… -
Whether you applied some fertilizer in the fall or apply it all in the spring, winter is a good time to assess your crop nutrition situation and make field plans and purchase decisions for the upcoming year. Here are some considerations the CCC team discussed in preparation for this month’s Canola Watch…
