“…Responses of native plants to biowastes are also influenced by baseline soil fertility and differ between plant species. Overall biomass and height responses are strongest in lowest fertility soils and for biosolids with the highest available N (Reis et al, 2017;Seyedalikhani et al, 2019), i.e., anaerobic digested biosolids with high NH +…”

“…A positive height and/or biomass growth response in native species is usually linked to a lower shoot: root ratio (Waterhouse et al, 2014;Seyedalikhani et al, 2019). For example, only aboveground biomass of tussock (Chionochloa rubra) and mānuka responded to 20% v/v biosolids addition, not root biomass, even though the control was an acidic, infertile mine soil (Seyedalikhani et al, 2019). Native monocots, for example harakeke (flax, Phormium spp.…”

“…Pot trials indicate biowaste-stimulated increases in biomass of kānuka (Kunzea ericoides) and mānuka retain essential oil qualities (a potentially lucrative industry) at application rates equivalent to over 2,500 kg N/ha (Seyedalikhani et al, 2019). Native plants can deliver specific ecosystem benefits, for example, mānuka limits amplification of some HM contaminants typically elevated in biowastes; Morrell (1997) identified low foliar bioaccumulation of TE in native plants as a particular benefit in trials using municipal biosolids to revegetate toxic, base-metal mine tailings.…”

“…Biowastes usually supply one or more primary benefits for plant growth, delivered by enhanced available N and P. However, because a positive height and/or biomass growth response in native species is usually linked to a lower shoot: root ratio (Waterhouse et al, 2014;Seyedalikhani et al, 2019), biowaste applications that stimulate a large above-ground growth are likely to reduce resilience on native plants to drought and windthrow (storms). Vulnerability to drought is increased where biowastes encourage development of a near-surface root mat, for example by regular surface application of wastewater (Sims et al, 1994) or use of surface mulches with fertilizer (Pratt, 1999).…”

“…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.

Purpose Planting strategies can be effective mechanisms to reduce diffuse pollution from agricultural catchments reaching water bodies. Plants with antimicrobial properties such as mānuka (Leptospermum scoparium) demonstrated in controlled conditions the ability to inhibit nitrification and growth of pathogens in soils. This potential in a real on-farm setting was still to be investigated. Methods In a stock-excluded riparian area, planted with mānuka on a dry stock farm, synthetic excrement patches high in urea (950 kg N ha−1 equiv.) and Escherichia coli (7.9 × 109 cfu plant-1) underneath mānuka saplings and pasture were applied. Soil was sampled at three depths over 21 days after the excrement application and analysed for total C and N, inorganic N, pH, soil moisture and E. coli. Results There was no significant difference between the pasture and mānuka for total C and N, C:N ratio, and soil moisture. E. coli was only different between both at 20–30 cm deep. NO3− - N and NH4+ - N concentrations were significantly lower under mānuka compared to pasture for the upper two soil depths (NO3− - N: 109 mg kg−1 vs 205 mg kg−1 in the topsoil). Conclusions The results of this study indicate that mānuka may inhibit urease activity and nitrification and could reduce on-farm nitrate leaching, while also highlighting that field conditions make quantifying such phenomenon more complex.
