There is no doubt that cover crop Broadleaves have a positive impact on soil health – especially Shield Mustard. From breaking the Carbon – Phosphorus bond, to exudates that are manufactured by the plant, to the sheer number of deep-penetrating roots, much of broadleaf plants contribution to soil health are still awaiting discovery. We are currently researching Bayou Kale and African Forage Cabbage, whose multiple fibrous roots (that resemble tap roots) can penetrate heavy clay soils and improve soil health in as little as four months. Among the other benefits broadleaf plants provide, there is evidence of broadleaf plants functioning as biofumigants that suppress soil pests and root pathogens. Broadleaf plants do not develop mycorrhizal fungi associations and can be included in mixes to promote the efficiency of other mixture components that do establish these associations.
