Leaving 30% crop residue has been proven to minimize top soil losses from wind and water erosion. But what does 30% soil cover look like? Do certain tillage implements leave less than 30% crop residue? Crop residue in the form of corn stalks or cereal straw, or green cover (growing crops or cover crops) are all effective ways to achieve 30% cover. In a demonstration at the Outdoor Farm Show in 2012 we learned that if we remove straw from a cereal crop and follow with any type of tillage we retain less than 30% residue. However, the tillage action stimulated a more uniform germination of volunteer cereals which increased total soil cover to well over 30%. The following photographs illustrate crop residue cover after tillage action on two differently managed field scenarios.
Two weeks ago we were talking about higher highs and no where to go but down for the cattle market and thats exactly what we got. The market corrected over the past two weeks which could be fine long term technically. What has hurt Canadian feedyards is that the Canadian dollar has rallied over that…Read more »
