The safe use of compost derived from municipal solid waste depends on its composition and conditions of application

Municipal solid waste compost (MSWC) is a source of organic C and other nutrients, which, when free from potential contaminants, can be used as soil amendment. This study was carried out over three years in vineyard with pH close to neutral under an experimental design consisting two treatments (with without MSWC). Application MSWC currently authorized national legislation vineyards, orchards forests at maximum rate 10 t ha?1 year?1. In this study, for purposes, double (20 year?1) used. The accumulated grape yield increased the amended plot by 28% dry biomass weeds between rows 119%. significantly some relevant properties such C, pH, cation exchange capacity (CEC) extractable P, K B. concentration several tissues, P decreased. However, K, essential nutrients leaves remained within their sufficiency ranges. Tissue levels heavy metals (Cr, Cd, Pb Ni) did not increase application, values pulp below limits established foodstuffs. results indicate that continuous application does seem sustainable, because risk causing nutritional disorders. Products similar composition should therefore only on more acidic soils never exceed legally rates.
