Why is this research important for Alberta ag?
Cover crops have been studied extensively in the past few decades and offer a means to reduce tillage (reduce C losses), while increasing soil organic matter (increase C input). Multiple studies have concluded the extent to which cover crops improve soil properties, such as water holding and drainage capacity, depends on their ability to produce high below-ground biomass.
Spring-seeded cover crops offer the advantage of full growing season. Deep-rooted cover crops, such as sweet clover, chicory and radish produce high amounts of below-ground biomass and improve soil permeability and infiltration.
This study aims to determine the impact of two 2-year crop rotations of deep-rooted cover crop mixtures and field crops on soil water holding and drainage capacity.
What benefits can producers expect from this research?
This research has the ability to help producers improve soil water holding capacity during periods of droughts and improve drainage capacity during periods of excess rainfall.
How will these research findings reach producers on-farm?
Findings will be showcased in annual reports, field tours, newsletters, workshops and seminars, and several social media posts.
