Sewage sludge application in agriculture is the simplest method of its management. Its content of organic and inorganic toxic components is a barrier to such management. Particular attention should be paid to the content of heavy metals whose presence in sewage sludge and later in soil poses hazard for plants, animals and people. The investigations aimed to determine the effect of vermicomposts obtained from tannery sludge on development of the root system and biomass of shoots as well as heavy metal concentrations in these organs. In the first year after the vermicomposts application their effect on the maize biomass increase was equal to the farmyard manure treatment but significantly worse than the mineral fertilization. The consecutive fertilizer effect of vermicomposts of tannery sludge ted on the increase in biomass of the shoots and roots of winter rape, sunflower and oats was comparable with the farmyard manure effect but notably better than the mineral fertilization. Heavy metal concentrations in individual plants were diversified; in the plants from vermicompost treatment they were as a rule lower than in the plants from mineral or farmyard manure treatment. Absorbed heavy metals accumulated primarily in the root systems, whereas the extremely high chromium content in vermicomposts did not cause its excessive accumulation in the cultivated plants.

Sludge Application

Studies were conducted to determine: (a) the heavy metal concentrations in Halton Region agricultural soils; and (b) whether a 1984 estimate of at least 39 yr for practicing land application of sludge in the Region was valid. Soil samples were taken on a regular grid pattern from the agricultural area of the Region. In a very large proportion of the samples, heavy metal concentrations were less than the maximum permissible values for sludge application to land in Ontario and in most of the samples, they were less than or approximately equal to the mean values for uncontaminated soils in Ontario. In a small proportion of the samples, heavy metal concentrations exceeded the maximum permissible values for sludge application to land in Ontario. These samples were obtained mainly west of the Niagara Escarpment in the southwest corner of the Region and the offending metals were primarily Pb and Zn. High Pb and Zn concentrations in these soils were not related to sludge application but were naturally occurring and probably were derived from Pb and Zn sulfides in the soil parent material. It was concluded that sludge may be applied on a very large proportion of the agricultural land in Halton Region and that the 1984 estimate of at least 39 yr for continuing this practice was valid. Moreover, in view of recent reductions in annual sludge quantity for land application in the Region and in sludge Cd concentration, the 39-yr estimate was considered to be conservative.

Sludge Application

This study describes the long-term effects of different sewage sludge application rates on vegetative parameters, morphological characteristics, yield, and chemical properties of fruit and leaves of sour cherry (Prunus cerasusL.) cv. “Kütahya.” A three-year field experiment was set up in a completely randomized block design with six sewage sludge application rates (0.0, 2.5, 5.0, 7.5, 10.0 and 12.5 kg of dry matter per tree) and three replications. One-year-old Kütahya sour cherry trees grafted onPrunus mahalebrootstock were evaluated. In all application rates, sewage sludge altered vegetative growth parameters, morphological characteristics, and yield. The most effective application rate was 7.5 kg per tree, it increased cumulative yield more than twofold. The results obtained in this study demonstrate that application of sewage sludge to light-textured soil is an effective means for improvement of vegetative growth and yield, and that a single application of sewage sludge sustains its effects for at least 7 years.
