This research evaluated the impact of purified municipal wastes from Lublin on nickel accumulation in tested plants due to varied rates of sewage. Moreover, the fodder value of some plants was estimated. The experiment was localized in Bystrzyca river valley in 1996, covering an 8-hectare area. Studies were carried out on soils: (division) hydrogenic, (type) bog and bog-like, (sub-type) peat-bog and mineralbog. The experimental field was divided into 7 blocks and each block into 3 quarters (a, b c). Sewage was applied at three rates under every cultivation: a – control; b – sewage rate optimum for a given plant (established on a base of N content and water demands); c – double optimum rate. Plant material was randomly collected in July and September 1997. The ability for nickel accumulation in the investigated plants decreased along the sequence: grass mixtures > rape > hemp > maize > poplar (leaves) > willow (leaves).
