“…Although L. scoparium naturally grows in low fertility environments (Stephens et al, 2005), its growth is enhanced by the addition of nutrients (Esperschuetz et al, 2017a,b; Reis et al, 2017). In this experiment, N was the limiting nutrient; its concentration in leaves when biosolids were added, was comparable to previous studies with this species (Esperschuetz et al, 2017a,b; Reis et al, 2017), and other native pioneer species (Dickinson et al, 2015; Gutiérrez-Ginés et al, 2017). Although it was not observed in this experiment, phosphorus and sulfur can also be limiting in other soil types (Reis et al, 2017).…”

Response of a Pioneering Species (Leptospermum scoparium J.R.Forst. & G.Forst.) to Heterogeneity in a Low-Fertility Soil

Root foraging may increase plant nutrient acquisition at the cost of reducing the total volume of soil explored, thereby reducing the chance of the roots encountering additional patches. Patches in soil seldom contain just one nutrient: the patch may also have distinct textural, hydrological, and toxicological characteristics. We sought to determine the characteristics of root foraging by a pioneering species, Leptospermum scoparium, using pot trials and rhizobox experiments with patches of biosolids. The growth of L. scoparium was increased by <50 t/ha equiv. of biosolids but higher doses were inhibitory. Roots foraged patches of biosolids in a low-fertility soil. There was no evidence of chemotaxis, rather, the roots proliferated toward the patch of biosolids, following chemical gradients of nitrate. While the biosolids also contained high concentrations of other nutrients (P, K, and S), only significant chemical gradients of nitrate were found. Once the roots encountered a patch of biosolids, the growth of the plant increased to a level similar to plants growing in soil homogeneously mixed with biosolids or surface-applied biosolids. Our results indicate that roots forage nitrate, which is mobile in soil, and that gradients of nitrate may lead to patches containing other less mobile nutrients, such as phosphate or potassium.

“…Some native species, notably kānuka and mānuka, also mitigate microbiological pathogens present in some biowastes (Prosser et al, 2016). In vitro and lysimeter studies show mānuka also inhibits nitrification processes in soil, potentially reducing NO − 3 leaching; both actions could enhance protection of surface and ground water (Esperschuetz et al, 2017a). Recent field experiments are testing the efficacy of planting these species into riparian areas of farms and areas used for municipal wastewater-disposal.…”

“…New Zealand ecosystems that are adapted to low available N and P are likely to be transformed by biowaste applications that elevate the availability of these nutrients. Because biowastes contain organic-bound N and P, the duration during which nutrients such as P, K, Mg, and Ca are available for plant growth is extended and potential for N leaching is reduced (Horrocks et al, 2013;Esperschuetz et al, 2017a). Partly-stabilized biowastes, such as vermi-composts with moderate levels of available N and P, and large proportions of slowly-mineralisable N and P, also offer solutions as they are more likely to match release to native plant demand, which is lower than for arable crops or plantation forestry.…”

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.

“…There are no reports of the effect of soil and plant elemental concentrations on the elemental composition and NPA of mānuka honey. L. scoparium is typically found growing on low fertility soils [ 23 ], and increased soil fertility accelerates growth of the plant [ 24 ]. Nickless et al [ 18 ] showed that increased soil nutrient concentration also improved floral density of L. scoparium .…”

Soil properties in the foraging range of honeybees influence honey composition. We aimed to determine relationships between the antimicrobial properties of New Zealand mānuka (Leptospermum scoparium) honey and elemental concentrations in the honey, plants, and soils. We analyzed soils, plants, and fresh mānuka honey samples from the Wairarapa region of New Zealand for the chemical elements and the antimicrobial activity of the honey as indicated by methylglyoxal (MGO) and dihydroxyacetone (DHA). There were significant negative correlations between honey MGO and the concentrations of Mn, Cu, Mg, S, Na, Ba, K, Zn, and Al. These elements may provide a low-cost means of assessing mānuka honey quality. For individual elements, except for K, there were no correlations between the honeys, plants, and soils. Soil nitrate concentrations were negatively correlated with concentrations of MGO and DHA in the honey, which implies that soil fertility may be a determiner of mānuka honey quality.
