Yielding and Bioaccumulation of Zinc by Cocksfoot under Conditions of Different Doses of This Metal and Organic Fertilization

Zinc is essential for the growth and development of plants, but in excessive amounts soil it can be toxic them. Its mobility depends part on organic matter content soil. The aim study was to investigate effect application increasing zinc (200, 400 600 mg Zn·kg−1 soil) together with various forms fertilizer (cattle manure, chicken manure spent mushroom substrate) yield cocksfoot uptake this metal, determine its bioaccumulation factor tolerance indices. A minor cocksfoot, expressed as a decrease yield, observed following Increasing caused significant yield. Application significantly reduced value Zn/Org index. levels increased by plants. All materials applied zinc. Spent substrate index, while cattle Org/Zn which confirms their protective action against high
