Pulse School: Adding pulses in rotation can keep soil acidification at bay


A soil pH outside the neutral range can cause significant issue with nutrient availability.

Western Canadian soils are largely in this range, however, over time, nitrogen fertilizer applications can create soil acidity issues that are very expensive to fix.

Dr. Manbir Rakkar, assistant research professor at Montana State University-Bozeman, explains that managing acidic soil conditions is very costly, so the main focus should be on preventing acidification in the first place.

What’s one way to reduce the risk? Why, it’s growing pulses, of course!

In this episode of the Pulse School filmed at Havre, Montana, field editor Kara Oosterhuis asks Rakkar to explain how soil acidification happens, why it matters, and what options farmers have to bring pH back into the neutral range:
