“…Ozores-Hampton et al (1999) found that municipal solid waste composted for 3 to 56 d could inhibit germination and growth of both weed and crop species, compared to 1 yr old compost, which may have been due to high concentrations of volatile fatty acids in the immature materials. Zmora-Nahum et al (2005) demonstrated that different compost types could inhibit growth of ryegrass (Lolium perenne L.) and cucumber (Cucumis sativus L.) if incorporated into soil when immature, arguing that compost stability is evident when dissolved organic C (DOC) concentration stabilizes.…”

“…There are many compositional changes that occur during the composting process, and these can be used as indices of compost maturity as it relates to nutrient availability, or of compost stability and associated effects on plant growth (Cooperband et al 2003;Ozores-Hampton et al 1999). Simple chemical measurements like total N or C:N ratio have been widely used, but the relationship between these constituents, the composting process, and the suitability of the compost for plant media have not been very robust (Brewer and Sullivan 2003;Cambardella et al 2003).…”

“…Thus the present study clearly shows that organic amendments suppress purple nutsedge growth. Previous studies have similarly documented that organic amendments may suppress weeds by releasing phytotoxins during decomposition, such as phenolic compounds (Ohno et al, 2000) and short-chain fatty acids (Ozores-Hampton et al, 1999). These compounds have been linked with allelopathic inhibition of weed growth (Liebman & Ohno, 1998;Ohno et al, 2000) and increased in the pathogenicity of soil-borne diseases (Dabney et al, 1996;Toussoun & Patrick, 1963).…”

“…At purple nutsedge densities of 20 and 40 plants/m 2 , its tuber weight when grown with improved compost was significantly (p<0.05) lower than in other N (Table 4). Previous studies have reported that compost can contain phytotoxic compounds, including short-chain fatty acids, phenols, and ammonia, each of which can inhibit weed seed germination (Ligneau & Watt, 1995;Marambe & Ando, 1992;Ozores-Hampton et al, 1999;Roe et al, 1993). In this study, improved compost could have released phytotoxic substances which may be detrimental to purple nutsedge tubers.…”

“…These reductions were near 50% of the density achieved with Ca(OH) 2 -stabilized MPW (data not shown). The reduction in early-season radish density by fresh MPW was potentially the result of products generated during decomposition of this proteinaceous material, such as volatile short-chain fatty acids (Beck-Friis et al 2000), lactic acid, and acetic acid (Shiralipour et al 1997;Beck-Friis et al 2001), which at elevated levels are phytotoxic (Nappi et al 1992) and negatively affect seed germination (Ozores-Hampton et al 1999;Madejón et al 2001).…”

MacLeod, J. A., Kuo, S., Gallant, T. L. and Grimmett, M. 2006. Seafood processing wastes as nutrient sources for crop production. Can. J. Soil Sci. 86: 631-640. Large quantities of wastes are generated in the processing of seafood such as shellfish, crustaceans and finfish. These materials contain appreciable amounts of plant nutrients which may be useful in cropping programs. Under some conditions the waste materials can be directly applied to soil but in other situations stabilization may be necessary. The method of stabilization will influence the availability of nutrients in various cropping programs. Composting with wood can effectively stabilize the waste but the slow mineralization of organic N can limit the usefulness of the compost. Combining the waste with calcium oxide (CaO) or hydrated lime [Ca(OH) 2 ] can produce a stable material with good nutrient availability. If application rates of various wastes are based on their nutrient content, the nutrient requirement of specific crops, and the heavy metal concentrations, then potential environmental problems associated with excess nutrient and heavy metal loadings can be minimized. Application of these materials to land can effectively supply nutrients to crops and minimize environmental damage due to inappropriate methods of disposal.Key words: Seafood waste, composting, lime stabilization, crop nutrients MacLeod, J. A., Kuo, S., Gallant, T. L. et Grimmett, M. 2006. Les déchets de la transformation des produits de la mer, source d'éléments nutritifs pour les cultures. Can. J. Soil Sci. 86: 631-640. La transformation des produits de la mer comme les mollusques, les crustacés et les poissons engendre beaucoup de déchets. Ces derniers renferment une quantité appréciable d'éléments nutritifs pour les plantes et pourraient avoir leur utilité en agriculture. Les déchets peuvent être épandus directement sur le sol dans certaines conditions, mais dans d'autres situations, une stabilisation s'impose. La méthode de stabilisation influera sur les éléments nutritifs disponibles pour diverses cultures. Ainsi, le compostage avec du bois stabilise les déchets, mais la lenteur avec laquelle l'azote se minéralise réduit parfois l'utilité d'un tel compost. En mêlant de l'oxyde de calcium (CaO) ou de la chaux éteinte [Ca(OH) 2 ] aux déchets, on obtient un matériau stable, riche en éléments nutritifs assimilables. On réduira au minimum les risques potentiels pour l'environnement associés à la surcharge d'éléments nutritifs ou de métaux lourds en fondant le taux d'application des déchets sur leur teneur en éléments nutritifs, les besoins de la culture et la concentration de métaux lourds. L'application d'un tel matériau sur les terres fournira efficacement les éléments nutritifs dont la culture a besoin et atténuera les dommages environnementaux attribuables aux méthodes d'élimination inappropriées.Mots clés: Déchets des produits de la mer, compostage, stabilisation par la chaux, éléments nutritifs pour les plantes Traditional nutrient cycling models tend to consider nutrie...
