Soil Health And Grazing Hot Topics In Edmonton

A Longview cattle producer was among the crowd in Edmonton last week at the Western Canada Conference on Soil Health and Grazing.
 
Alex Robertson, who's also the Foothills Forage and Grazing Association Vice-Chair, says he enjoyed listening to speaker Gabe Brown and his five principles of soil health.
 
"Eliminating disturbance, keep the soil covered, plant diversity, keep roots in the soil, then integrate animals into the whole system," Robertson lists. "That's basically mother nature's way of how the lands evolved."
 
He says the healthier the soil is, the greater the water retention, and the higher the organic matter.
 
"Our soils have been depleted in organic matter over the last hundred years, probably from 7,8 per cent down to 2 or 3 per cent through continuous cropping, so if you can get this organic matter returned, which is actual carbon out of the atmosphere, to build the organic matter, then it helps in both ways."
 
Robertson explains this also increases the life in the soils, adding one teaspoon of soil has more microbes than the number of people on the planet.
 
He points to the growth in attendance as one of the big highlights of last week's conference. 
 
Robertson says the event taking place every other year was sold out for the second time in a row, with attendance increasing from 100 people to 550 since the last event.
 
He says soil health and grazing is an important topic, as producers are always challenged by those saying cattle are bad for the environment.

White rot, also known as sclerotinia, is a common agricultural fungal disease caused by various virulent species of Sclerotinia. It initially affects the root system (mycelium) before spreading to the aerial parts through the dissemination of spores.

Sclerotinia is undoubtedly a disease of major economic importance, and very damaging in the event of a heavy attack.

All these attacks come from the primary inoculum stored in the soil: sclerotia. These forms of resistance can survive in the soil for over 10 years, maintaining constant contamination of susceptible host crops, causing symptoms on the crop and replenishing the soil inoculum with new sclerotia.
