If you have low soil pH, should you lime?

It can take tonnes of lime per acre to move soil pH from 5 to 7, but improved fertilizer availability for all crops, better nodulation for pulse crops and alfalfa, and reduced risk from clubroot in canola can make the investment worthwhile

Six steps to help prevent clubroot in canola

Back in 2013, John Guelly discovered some dead canola plants with ominous-looking root galls at his Westlock-area farm. But even though clubroot was already known to be in his area, he hadn’t seen it himself, and he wasn’t sure what it looked like. People were secretive about the disease, he told farmers, agronomists and other[...]
