However, to optimize it a detailed knowledge of its effects on ecosystem components such as plants, soil, water and fauna is needed. We investigated the effects of sewage sludge application on soil, tree growth and floristic diversity in a ten-year-old plantation of European larch (<ce:italic>Larix decidua</ce:italic>Mill.). Our one-hectare study site, located at Mélisey, Haute-Saône, France (47°753′ Lat., 6°580′ Long.), was subdivided into six plots. Three plots, alternating with three control plots (no sewage sludge application), were amended in June 2008 with 0.4tDWha<ce:sup loc="post">−1</ce:sup>obtained from a municipal urban wastewater treatment plant in Mélisey. Within each plot, one subplot was delimited and sludge was again manually applied at 3t of DWha<ce:sup loc="post">−1</ce:sup>in July 2009 and March 2010 to the soil surface of the amended subplots without incorporation. The results showed no effect on radial and height growth of European larch amended with 0.4tDWha<ce:sup loc="post">−1</ce:sup>. While a significant temporary increase in pH, macro-element contents (N, P and Ca) and the trace metal (Cu and Zn) concentration in the soil was observed, it had no significant effect on needles and sporocarp contents. The number of species in the amended subplots with 3tDWha<ce:sup loc="post">−1</ce:sup>year<ce:sup loc="post">−1</ce:sup>increased by 80% compared to the control. However, the relative species abundance present only in amended subplots remains <1, except for<ce:italic>Hypericum humifusum</ce:italic>.</ce:simple-para></ce:abstract-sec></ce:abstract><ce:abstract xmlns:ce="http://www.elsevier.com/xml/common/dtd" xmlns="http://www.elsevier.com/xml/ja/dtd" id="ab0010" class="graphical" xml:lang="en" view="all"><ce:section-title id="st0010">Graphical abstract</ce:section-title><ce:abstract-sec id="as0010" view="all"><ce:simple-para>Display Omitted</ce:simple-para></ce:abstract-sec></ce:abstract><ce:abstract xmlns:ce="http://www.elsevier.com/xml/common/dtd" xmlns="http://www.elsevier.com/xml/ja/dtd" id="ab0015" class="author-highlights" xml:lang="en" view="all"><ce:section-title id="st0015">Highlights</ce:section-title><ce:abstract-sec id="as0015" view="all"><ce:simple-para id="sp0110" view="all"><ce:list id="l0005"><ce:list-item id="li0005"><ce:label>•</ce:label><ce:para id="p0005" view="all">The impacts of sewage sludge application in larch plantation were studied.</ce:para></ce:list-item><ce:list-item id="li0010"><ce:label>•</ce:label><ce:para id="p0010" view="all">Lack of sewage sludge effects on soil and underwood diversity.</ce:para></ce:list-item><ce:list-item id="li0015"><ce:label>•</ce:label><ce:para id="p0015" view="all">No significant effects on diameter and height growth of larch tree</ce:para></ce:list-item><ce:list-item id="li0020"><ce:label>•</ce:label><ce:para id="p0020" view="all">No accumulation of Cu, Zn, Pb and Cd in larch needles and edible sporocarps</ce:para></ce:list-item><ce:list-item id="li0025"><ce:label>•</ce:label><ce:para id="p0025" view="all">Small dose (0.4tDWha<ce:sup loc="post">−1</ce:sup>) explains lack of effects on analyzed parameters</ce:para></ce:list-item></ce:list></ce:simple-para></ce:abstract-sec></ce:abstract> 收起
