“…With C:N ratios of 150-300 in RDS, N deficiency is likely to occur in sludge-amended soils (Zibilske 1987;Bellamy et al 1995). For example, when the C:N ratio is high (typically greater than 30:1), soil microbes immobilize inorganic soil N into microbial biomass, and decrease its plant availability (Tripepi et al 1996). The recommended strategies to minimize nutrient deficiencies due to organic by-products consist of reducing sludge application rates, delaying planting for some period after sludge application or applying supplemental N-mineral fertilizer to soil or sludges (Simpson et al 1983;Bellamy et al 1995).…”

, J. 1998. Effects of de-inking paper sludges on soil properties and crop yields. Can. J. Soil Sci. 78: 689-697. The paper mills in Quebec produce approximately 330 000 Mg of raw de-inking paper sludges (RDS) per year. These residues are rich in cellulose and lignin and may be used as soil conditioner. The effects of RDS on soil chemical properties, barley (Hordeum vulgare L. 'Chapais') growth, nutrient uptake and yields, and their residual effect on a subsequent strawberry (Fragaria × ananassa Duch. 'Kent') crop were investigated on a Tilly silt loam (Gleyed Humo-Ferric Podzol) from 1994 to 1996. Four rates of RDS (0, 15, 30 and 45 Mg ha -1 ) on a wet-weight basis were combined with four rates of supplemental N-mineral fertilizer (0, 45, 90 and 135 kg ha -1 ) as NH 4 NO 3 . The soluble inorganic N content of soil sampled 30 d after treatment application was significantly lower in plots treated with 45 Mg RDS ha -1 at all N rates. However, soluble inorganic N concentrations increased significantly with RDS rate to 20-cm depth in June 1995. The RDS application increased soil water content and Mehlich-3-extractable P, K, and Ca in the first year. Barley yields were reduced by 50% when 45 Mg RDS ha -1 was applied without supplemental N-mineral fertilizer. The amount of N-mineral fertilizer needed to overcome N immobilization resulting from RDS increased with RDS rates. Strawberry yields were not significantly affected by residual RDS or N-mineral fertilizer. Changes in plant tissue metal contents were not significant. The results of this study indicate that RDS application has a positive short-term effect on soil water, P and K availability but reduces plant-available soil N in the growing season after spring application. The RDS may be used effectively as soil amendment if the crop receives adequate supplemental N-mineral fertilizer. Par contre, l'azote minéral dans la couche de 0-20 cm de sol en juin 1995 augmentait avec la dose de BDD. Les BDD ont entraîné une augmentation de la teneur en eau et en carbone du sol lors de l'année d'application. De plus, les teneurs en P, K et Ca extractibles par la solution Mehlich-3 ont augmenté suite à l'apport de BDD. Un apport de BDD à raison de 45 Mg ha -1 a diminué le rendement d'orge de 50%. Un apport supplémentaire de N minéral a résulté en une augmentation de rendement d'orge. Les BDD n'ont pas eu d'effet résiduel sur la production de fraises. Aucune augmentation de la teneur en métaux lourds n'a été détectée dans les tissus d'orge ou de fraises. Ces résidus peuvent être considérés comme un amendement organique. Toutefois, un apport supplémen-taire d'azote minéral à la culture doit être envisagé pour éviter les problèmes de carence en N.

. 1998. Comparative rooting of deciduous landscape shrub cuttings in media amended with paper mill biosolids from four different sources. Can. J. Plant Sci. 78: 519-526. Scarcity of landfills has resulted in increasing need for alternative disposal or reuse of industrial organic wastes such as paper mill sludge (biosolids). The objective of this study was to evaluate and compare the rooting response of stem cuttings from six species of deciduous landscape shrubs [coralberry (Symphoricarpos × chenaultii Rehd. 'Hancock'); flowering almond (Prunus triloba Lindl. 'Multiplex'); honeysuckle (Lonicera × xylosteoides Tausch. 'Clavey's Dwarf'); mock orange (Philadelphus × virginalis Rehd. 'Minnesota Snowflake'); purple-leaf sandcherry (Prunus × cistena N. E. Hansen); and viburnum (Viburnum dentatum L.)] under mist and 50% shade (outdoor lath) in flats filled with 100% perlite medium, or perlite mixed with 15, 30, 45 or 60% of fresh paper mill biosolids, by volume, of one of four sources (Atlantic, Domtar, Thorold, and QUNO). There was little or no adverse effect of the biosolids, despite wide variability in rooting response due to species, source and/or level of biosolids. Regression analyses indicated that, with few exceptions, the percent rooting, mean root number per rooted cutting, and length of longest root per cutting increased linearly or curvilinearly, or was unaffected, when regressed over level of biosolids. Optimum amounts of biosolids in the rooting medium ranged from 30 to 60% by volume. The electrical conductivities of the biosolids-amended media were acceptable (0.1-0.3 dS m -1 ) for rooting of woody cuttings and pore space characteristics were comparable to, or exceeded those of, perlite. symphorine (Symphoricarpos × chenaultii), amandier ornemental (Prunus triloba Lindl. cv. Multiplex), chèvrefeuille (Lonicera × xylosteoides Tausch. 'Clavey's Dwarf'), syringat (Philadelphus × virginalis Tausch. 'Minnesota Snowflake'), cerisier à feuilles pourpres (Prunus × cistena N. E. Hansen) et viorne (Viburnum dentatum L.). Les boutures étaient mises en plateau sous nébuli-sation, en ombrière extérieure (50 % d'ombrage). Les substrats étaient faits de perlite à 100 % ou mélangée avec 15, 30, 45 ou 60 %, en volume de boues d'épuration fraîches de papeterie de l'une ou l'autre des provenances suivantes : Atlantic, Domtar, Thorold et QUNO. Les boues ne causaient pratiquement pas d'effets négatifs, malgré la large variabilité du racinage liée à l'espèce végétale et à la provenance ou à la dose d'incorporation des boues. À partir de l'analyse de régression, nous avons constaté qu'à quelques exceptions près, le pourcentage d'enracinement, le nombre moyen de racines par bouture racinée et la longueur de la plus longue racine par bouture augmentaient en fonction linéaire, curvilinéaire ou pas du tout, selon la dose d'incorporation des boues. Les doses optimales se situaient entre 30 et 60 % en volume. Les valeurs de conductivité électrique des substrats contenant des boues étaient acceptables (0,1 à 0,3 dS m -1 ) pour l'enra...

“…Other researchers have also successfully used paper mill sludge to amend soils for field-grown horticultural crops (Tripepi et al 1996b) and used it raw or composted (Tripepi et al 1996a) in substrates for container grown nursery crops. Chong and Hamersma (1996a) demonstrated an alternate use of sludge (QUNO) as a medium amendment for rooting of deciduous woody cuttings under mist.…”

The nursery/landscape industry has been one of the fastest growing agricultural sectors in Canada. Since 1980s, the Ornamental Nursery Research Program at the Horticultural Research Institute of Ontario (HRIO) has been conducting research which focuses on environmentally friendly production practices. Emphasis is on the use of composted or uncomposted organic wastes as amendments in container potting mixes. Various projects have evaluated mixes derived from wastes such as spent mushroom compost, paper mill sludge, apple pomace, and various types of barks. In the late 1980s and early 1990s, the scope of the research expanded to include composting and a wider assortment of wastes such as waxed corrugated cardboard, municipal solid waste compost, wood chips from pallets and furniture and demolition wastes, food wastes, and organic fertilizers manufactured from meat by-products, and selected industrial wastes. Presently, paper mill sludge is being evaluated as field soil amendment for growing nursery shade trees and also for use in rehabilitating marginal, non-agricultural land. Key words: Waste recycling, land rehabilitation, composts, organic wastes, container culture, shade tree culture, ornamentals, nutrition
