Assessing the efficacy of extruded seed pellets and microbial amendments for native revegetation

Worldwide, there is a strong need for new, innovative, large‐scale approaches to restoring diverse native vegetation. Seed‐based revegetation, while often employed, can suffer from low plant establishment. Various seed coating technologies have been widely employed decades promote efficient agricultural planting; however, significant obstacle the implementation of this technology species revegetation limited access expertise and techniques which are mostly confidential specialized agrochemical industry. Here we investigated whether seeds Australian may benefit extruded pelleting, measuring both seedling emergence early growth, testing pellets with without addition commercial probiotic. A manipulative glasshouse experiment was carried out three treatments (bare seeded; standard pellets; amended probiotic) four species. Incorporation within shown maintain high percentages improve growth tested ( Daviesia ulicifolia , Hardenbergia violacea Indigofera australis ) in setting, increases mean biomass 83, 385, 1,002%, respectively. However, fourth Bursaria spinosa all treatments, perhaps due excessive sowing depth seeds), combined being encased inside pellet. Relative pellets, probiotic did not impart further detectable or benefits. Ultimately, these results highlight exciting prospects application facilitating use some
