Supplementation of Organic Amendments Improve Yield and Adaptability by Reducing the Toxic Effect of Copper in Cocksfoot Grass (Dactylis glomerata L. Cv Amera)

Copper is an element necessary for the proper growth and development of plants, but when taken in excess amounts, it can be toxic. Its availability plant reduced by using organic fertilizers or soil liming. The aim study was to investigate effect increasing doses copper (100, 200, 300 mg Cu·kg?1 soil) application combination with various amendments (cattle manure, chicken spent mushroom substrate) on yield cocksfoot its content uptake this metal, determine coefficient bioaccumulation tolerance indices. toxic manifested significant decrease test after mg·kg?1 soil. Increasing increased plant, while observing decreasing factor. All cocksfoot. most effective amendment terms protective effects against high levels cattle case which Org/Cu Cu/Org indices were highest.
