“…In contrast, Chang and Broadbent (1981) reported that the amount of COs evolved from soils amended with alfalfa meal and sewage sludge decreased by the addition of only 50 mg Cu kg -~. In their experiment, since Cu was added as a sulfate at the beginning of the incubation, a high concentration of Cu 2+ was likely to be present in the soil solution during the early period of incubation.…”

“…In most of the incubation experiments aimed at assessing the effects of heavy metals on the decomposition of plant materials by the addition of metals to soils (Chang and Broadbent 1981;Komai et al 1981), the soils were incubated along with the addition of heavy metal salts. In the apple orchard soils, however, the bulk of Cu is occluded by oxide materials and specifically adsorbed on soil particles (Hanada and Iwaya 1978).…”

“…The toxic effect of heavy metals on the soil respiration rate has been reported by many authors (Doelman and Haanstra, 1979;Chang and Broadbent, 1981;Laskowski et al, 1994). In heavily polluted environments this results in the accumulation of undecomposed organic matter, and a number of authors have suggested that this harms forest health and productivity (Tyler, 1972;Ru¨hling and Tyler, 1973;Jackson and Watson, 1977;Strojan, 1978;Berg et al, 1991).…”

The effects of heavy metal accumulation associated with the application of Bordeaux mixtures and lead arsenate on the decomposition of cellulose powder and orchard grass shoots in soils were investigated by laboratory incubation experiments. The largest amounts of total Cu, Pb, and As found in the soils used were 1,108, 1,271, and 205 mg kg -1 soil, respectively, and the amounts of Cu and Pb extracted with 0.1 M CaC12 were each negatively correlated with the soil pH. The rates of decomposition and C mineralization of the cellulose powder added to the soils decreased exponentially with the amount of 0.1 M CaC12-extractable Cu and increased exponentially with the soil pH over the 35-d period of incubation, though they did not show a close relation to the total amounts of heavy metals. When the pH was modified in acid soils by the addition of Ca(OH)2, the increase in the soil pH enhanced the decomposition and C mineralization of added cellulose powder regardless of the accumulation of heavy metals. These results suggested that the decomposition of cellulose powder in soil was inhibited not only by the increase in the 0.1 M CaC12-extractable Cu, but also by the decrease in soil pH. No close relationship was detected between the total amount of heavy metals and the mineralization rate of the added orchard grass-C in the soils throughout the 70-d period of incubation. However, only during the early period of incubation (up to 7 d), the mineralization rate was negatively correlated with the amounts of 0.1 M CaC12-extractable Cu and Pb, and positively with the soil pH. The addition of Ca(OH)2 decreased the mineralization rate of orchard grass in an acid soil with heavy metal accumulation, whereas it did not affect appreciably the mineralization rate in an acid soil without heavy metal accumulation. It was suggested that the increases in the amounts of 0.1 M CaC12-extractable Cu and Pb induced by the decline in soil pH may be responsible for the inhibition of the decomposition of orchard grass observed during the early period of incubation.Key Words: cellulose decomposition, copper, heavy metals, lead, plant residue decomposition.Aomori Prefecture is the oldest and largest apple-producing region in Japan, accounting for about half of the total output. In Aomori Prefecture, considerable amounts of metal-based pesticides, Bordeaux mixtures and lead arsenate, have been applied in apple 1 Present address: Aichi Prefectural Government Toyota Office, Toyota, 471 Japan. 122M. AOYAMA and S. KUROYANAGI orchards since the early 1900's. The use of lead arsenate was prohibited in 1978, but Bordeaux mixtures are still utilized. As a result high concentrations of Cu, Pb, and As derived from such metal-based pesticides have accumulated in the surface soils of apple orchards (Narita et al. 1987). In apple orchards under the sod culture system, the undergrowth is considered to be playing an important role in the cycling of nutrients in soil. Heavy metals usually, but not always, inhibit the decomposition of organic matter in soil (Babich...
