No-till seeding had two primary objectives when it first began to gain prominence on Canada. One was to reduce the erosion of fragile erosion-prone soils and the other was for the financial benefit that low-impact, one-pass seeding provides by reducing the time equipment would need to run (fuel savings, equipment wear and tear) and labour time saved.
In addition to these initial objectives, no-till has also been shown over time to restore soil fertility and improved moisture and water management, a significant benefit in arid regions. By not tilling the field, the stubble that remains increases snow capture and spring soil moisture levels. This contributes to greater levels of soil organic material which also contributes to moisture conservation in the soil. The end result of all of this is that there is a quantifiable increase in carbon sequestration in the soil.
No-till has stabilized fragile Canadian soils and increased their fertility. This has made Canadian farmers more competitive and increased their resiliency to climate issues and also increased their yield potential.
For Canola crops alone, an estimated one million tonnes of carbon is either sequestered or no longer released annually as a result of some no-till practices.
In the 2011 Canadian census of agriculture is was found that for the first time, no-till practices accounted for more than half of all area prepared for seeding across Canada. Overall, 17.1% more farms reported using no-till practices than in 2006.
