Abstract: Refuse compost and sewage sludge were mixed with a loamy sand at various rates in pots and sown with Brassica chinensis, Daucus carota and Lycopersicon esculentum in a glasshouse. A commercial fertilizer was also applied to the same soil for comparison. Dry matter production of the three crops and contents of Cd, Cu, Mn, Pb and Zn in the harvested tissues were determined at the end of the experiment.In general, crop yield in refuse compost treatment was improved over that in sandy soil alone, but was less than… Show more

“…However, in regards to cadmium and zinc they apparently depend on the cultivated plant species. According to Chu and Wong (1987) and Galler (1992) these barriers exist also in the way the metal is transported among the above ground parts.…”

“…On the other hand, mineral fertilization resulted in greater Ni in radish and Cu in onion and tomato. Comparative studies of organic versus mineral fertilization have rarely addressed the effect of trace metal accumulation (Chu and Wong 1987;Singh et al 2010;Zaccone et al 2010;Christensen and Elsgaard 2014), often with controversial results (Liñero et al 2015). Consistently, a priority of the research is to address the understanding of how organic matter may affect (e.g.…”

“…Depending on the species, Mn may accumulate more in the leaves, as in carrots, or in the roots, as in Brassica chinensis and Lycopersicum esculentum (Chu and Wong, 1987), than in the shoot height. In this study, notwithstanding the part of the plant analyzed, Mn content was higher and significantly different every time pure RH was utilized during leaf formation.…”

“…As for the stem and leaves, no significant differences in content were found among the treatments. There is usually a higher accumulation of Pb in the root than in the shoot height (Chu and Wong, 1987) in Brassica chinensis and Lycopersicum esculentum, as well as in wheat (Arteaga, 1996). However, Pb may accumulate more in the shoot height than in the root in carrots (Chu and Wong, 1987).…”
