“…The interactions between species, particularly with competing weed species, are reported. Most studies investigating the interactions between biowastes and NZ native plants have been conducted in highly controlled glasshouse and laboratory trials (e.g., Xue et al, 2012;Waterhouse et al, 2014;Gutiérrez-Ginés et al, 2017b;Seyedalikhani et al, 2019 with few field studies Parker, 2011;Xue et al, 2015. Most research has used municipal biosolids from three urban areas (Auckland, Kaikoura, or Christchurch), although these biowastes have changed as treatment processes and inputs changed.…”

Biowastes can enhance the establishment of New Zealand (NZ) native vegetation, particularly on degraded land, where biological or physicochemical deficiencies limit plant growth. We identified critical success factors influencing selection and use of biowastes for a) growing native plants and b) rehabilitating native ecosystems. These were: weed competition; resilience (especially to drought and storms); ecosystem succession; and soil microbiome responses to elevated Nitrogen, Phosphorus, Organic Matter (OM) and contaminants (including Trace Elements). These factors determine the selection, timing and methods of biowaste application, selection of plant species and target ecosystems, and post-application management of receiving sites. Commonly planted native NZ species benefit from biowastes application where soils have depleted OM or sites with surface crusting, erosion, or high exposure to wind and temperature fluctuations. Commonly planted native species display luxury uptake of macro-nutrients, even on soils that are low-fertility under agricultural standards. Therefore, the growth responses to additional nutrients may be small. In contrast, most exotic weeds outcompete NZ species in high fertility soils. Therefore, biowaste application should not result in excessive nutrient availability. This can be achieved by using blends that contain a high-carbon biowaste, such as wood-waste, which immobilizes some macronutrients in the short term. We recommend long-term research using mixed-species field trials to identify biowastes and application methods that together support development of resilient native ecosystems. In particular, research should determine the role of biowastes on the beneficial mycorrhizae and native soil fauna. Application methods that enhance heterogeneity may help retain and/or build responsive microbiomes while conserving "native" microbiomes to deliver sustainable, rehabilitated native ecosystems.

“…A menor concentração de N na casca das árvores adubadas apenas com o lodo de esgoto (LSF) pode ser atribuída à rápida mineralização do nitrogênio orgânico contido no lodo e, consequentemente, à perda de N por volatilização e lixiviação ao longo do tempo. Xue et al (2015), após estudarem por 19 anos a utilização de biossólido em plantios de Pinus radiata na Nova Zelândia, constataram que a aplicação periódica de lodo (a cada três anos) pode estimular continuamente o crescimento dos pinheiros, visto que a frequente adição de nitrogênio e dos demais nutrientes ao solo supre as perdas por lixiviação e volatilização.…”

A aplicação de lodo de esgoto em plantações florestais permite a reciclagem da matéria orgânica e dos nutrientes, entre os ambientes urbanos e agroflorestal, podendo contribuir para um menor consumo de fertilizantes minerais. O objetivo deste trabalho foi avaliar o crescimento e a produção de biomassa lenhosa em plantios de Pinus caribaea var. hondurensis, bem como a exportação de nutrientes via colheita da madeira (lenho + casca) após nove anos do plantio, em resposta à aplicação de lodo de esgoto seco e fertilização mineral. Estimou-se o "balanço de nutrientes" pela diferença entre a quantidade de nutrientes adicionada com a fertilização e a quantidade de nutrientes exportada com a colheita da madeira. O delineamento experimental utilizado foi em blocos casualizados, com quatro repetições e quatro tratamentos: 1) Controle, sem qualquer fertilização (C); 2) Fertilização mineral (FM); 3) Fertilização com 18 t ha-1 (base seca) de lodo de esgoto sem adição de fertilizantes minerais (LSF) e 4) Fertilização com 18 t ha-1 (base seca) de lodo complementado com fertilizantes minerais (LCF). Até os seis anos de idade, as árvores fertilizadas com lodo (LSF e LCF) apresentaram diâmetro à altura do peito (DAP) e altura do tronco superiores (7 a 12%), o que resultou maior volume de madeira (cerca de 20%) em relação às árvores dos tratamentos C e FM. Aos nove anos de idade, o volume e a biomassa de tronco foram semelhantes entre os tratamentos. De modo geral, a exportação de nutrientes via colheita do tronco foi maior no tratamento LCF; mesmo assim, o balanço de nutrientes nos tratamentos com lodo foi positivo e superior aos tratamentos C e FM, principalmente para os elementos N,

“…This concurred with Horswell et al (2014), who reported that T-RFLP analyses showed >80 % similarity for the treatments in the Horotiu soil. Tolerance or resistance to triclosan has been demonstrated to occur in in vitro studies (Heath et al 1998;Gomez Escalada et al 2005;Webber et al 2008a;Webber et al 2008b), but several in vivo studies did not find any increase in tolerance after triclosan exposure, including one study where biosolids containing residues of triclosan had been applied to land for 13 years (Cole et al 2003;McBain et al 2004;Ledder et al 2006;Xue et al 2015). In the current study, exposure to triclosan did not increase the tolerance of soil microbes to triclosan.…”

Purpose Sewage sludge and biosolid application to land is a common approach to fertilise soils, but sewage-derived contaminants like the antimicrobial agent triclosan, and heavy metals zinc and copper, are known to affect soil microbial communities. In this study, the tolerance to triclosan was examined for soil microbial communities chronically preexposed to one of two heavy metals (Cu or Zn) and the antimicrobial triclosan. This was investigated in two different soil types. Materials and methods The impacts of chronic exposure of copper, zinc and triclosan as individual compounds or in mixtures on soil microbial communities were assessed in soils collected from two sites. The first was a Horotiu sandy loam with ample carbon and nitrogen levels and the second was a Templeton silt loam with very low carbon and nitrogen levels. The end points used to characterise the response of the soil microbial community were biomass, metabolic activity and pollution-induced community tolerance (PICT) to triclosan (using Biolog EcoPlates). In addition, metabolic activities for individual substrates were examined and those that significantly changed with the applied treatments were identified. Results and discussion Exposure to mixtures of both triclosan and copper in the Horotiu sandy loam reduced microbial biomass, increased metabolic activity and reduced microbial tolerance to triclosan. The decrease in soil microbial tolerance correlated with an increased metabolic activity for N-acetyl-Dglucosamine providing a potential link between triclosan exposure and nitrogen mineralisation. Exposure to both triclosan and high zinc levels decreased microbial biomass in the Horotiu sandy loam but did not have an effect on microbial tolerance to triclosan. In the finer-textured and less fertile Templeton soil, microbial tolerance to triclosan and the microbial biomass were not impacted by copper/triclosan or zinc/triclosan mixtures. Conclusions Mixture effects could become a cause for concern when soil microbial communities are exposed to triclosan in fertile soils with copper concentrations in excess of 50 mg kg −1 and could be especially important in the more coarsely textured soils. Current regulations for soil contaminants only consider the risk and effects of single contaminants. Greater protection of soil resources could result from considering mixture effects and soil types.
