“…Bokashi fermentation (Japanese term for 'fermented organic matter') uses facultative anaerobic lactobacilli bacteria to convert sugar into lactic acid, which results in improved growth, yield, quality and protection of vegetables and crops (Dou et al 2012). Most published studies (70%) reported a positive effect of such lactic fermented bokashi amendment on the growth of vegetables (Olle and Williams 2013), as well as on plant available nutrients (available P) and crop yield (Liu et al 2012;Andreev et al 2016). However, no systematic research exists on the agronomic effect of lactic fermented bokashi-biochar mixtures.…”

“…Moreover, EM applications were reported to increase the quantity of soil microflora, based on density estimates of colony-forming units of total bacteria using soil extract agar medium, total fungi using rose-bengal streptomycin agar medium and total actinomycetes using Jensen's medium. According to Olle and Williams [43] 70% of publications reported a positive effect of EM on vegetable growth. Moreover, Wididana and Higa [44] showed that foliar application of EM can increase the growth and yield of vegetable crops in a relatively short time.…”

Every year there are changes in the register of fungicides available for forestry. It is proactive to develop a new strategy to minimise the application of chemical methods and replace them with natural and biological fungal control options. This study compares the influence after one growing season in a bare-root forest nursery of (a) effective microorganisms (EM) consisting of mixed cultures of beneficial and naturally-occurring microorganisms, (b) the organic fertilizer Actifos (Act), and (c) the mineral fertilizer Busz Forte (BF) on the growth and mycorrhizal colonization of two common forest deciduous tree species: Fagus sylvatica and Quercus robur. None of the analysed growth parameters (root collar diameter, length of shoots and roots, dry mass of shoots, and roots) of either tested tree species differed significantly among treatments. For both tree species, seedlings treated with EM exhibited partnerships with a smaller species richness of mycorrhizae than did seedlings in other treatments. Moreover, EM treatment significantly increased the abundance of non-vital root tips for both species. By contrast, BF exerted a negative effect on F. sylvatica non-vital mycorrhiza abundance. Based on morphological and molecular identification, a total of 11 ectomycorrhizal (ECM) fungal taxa were detected in this study; three species (Peziza ostracoderma, Scleroderma areolatum and Cenococcum-like) were shared between both plant species. Across treatments, the most abundant ECM fungal species on F. sylvatica roots were Pezizaceae sp. (51.1%) and Hebeloma sp. (38.1%), while Peziza ostracoderma (26.8%), Naucoria salicis (24.1%), and Scleroderma areolatum (16.9%) were the most abundant taxa on Q. robur seedling roots. Our data indicate a negative effect of EM on ectomycorrhizal colonisation and on species richness of ECM fungi associated with F. sylvatica and Q. robur seedlings. None of the tested products had a negative effect on seedling growth, but seedlings treated with EM were characterised by a significant higher abundance of non-vital mycorrhizae.

“…LAB can increase yields and plant growth. Olle and Williams (2013) noted yield increases of 43% in peas in Europe. Similar studies have noted increases in the yield (Iwaishi, 2000;Khaliq et al, 2006) of rice and cotton, but few studies of the effects of EM on orchard crops have been performed, and no studies have addressed the effects of EM on macadamia production.…”

Macadamia (Macadamia integrifolia, Maiden & Betche) orchard management in Hawaii can result in the loss of organic matter and soil degradation. The objective of this study was to determine the effects of macadamia husk mulch, husk mulch combined with biochar, husk mulch combined with effective microorganisms (EM), soil profiling, and wood chip mulch on yield, nut quality, root growth, and SPAD values during a 1-year study of mature macadamia orchards at two locations in Hawaii. A partial cost–benefit analysis was performed to compare the costs and yield benefits of each treatment. Soil profiling resulted in higher yields than any other treatment, at a mean of 86.6 kg wet-in-husk per tree. No treatments significantly affected nut quality or dry kernel weight. Nut quality was affected by harvesting time, with the earliest harvesting (Aug. 2017) period resulting in the highest recovery rate of number 1 grade kernels (33%). SPAD values increased with the husk mulch combined with EM (6.5%) treatment and soil profiling treatment (6.9%). Husk combined with EM caused an 87% increase in total root biomass during the study period due to increased proteoid root biomass. The soil profiling treatment had the second lowest estimated cost per hectare and had the highest estimated partial profit per hectare. Soil profiling is a destructive management practice and should be used judiciously until its long-term effects on orchard health are studied. The inoculation of EM or sugar signaling may have been responsible for the proliferation of proteoid roots with the husk mulch and EM treatment.
