“…(yeast), actinomycetes, and various forms of filamentous fungi (Xu, 2000). Some of these microorganisms are considered antagonistic and capable of inducing systemic resistance in plants to various pathogens, including 'Candidatus phytoplasma solani' on periwinkle [Catharanthus roseus (L.) G. Don], bacterial blight (Erwinia psidii R.) on guava (Psidium guajava L.) fruits, Pythium ultimum Trow in cucumber (Cucumis sativus L.), and Rhizoctonia solani K€ uhn in carrot (Daucus carota L.) (Pierce et al, 2016;Rezende et al, 2008;Shin et al, 2017). The pores in biochar provide habitat for these microorganisms, protecting them from predation and drying (Lehmann et al, 2011).…”

Biochar, a carbon-rich, fine-grained residue obtained from pyrolysis of biomass, is known to improve soil conditions and to suppress infection by soilborne pathogens. However, its use as a soil amendment has received relatively little attention by the horticulture industry. Two 12-week experiments were conducted in a greenhouse to determine the potential of using biochar, produced from mixed conifers during conversion of wood to energy, as a soil amendment for highbush blueberry (Vaccinium hybrid ‘Legacy’). Plants in the first experiment were fertilized once a week with a complete fertilizer solution, whereas those the in the second experiment were fertilized once a month with a solution of ammonium sulfate. In both cases, the plants received the same amount of N in total and were grown in pots filled with unamended soil (sandy loam) or soil amended at rates of 10% or 20%, by volume, with biochar or a 4:1 mix of biochar and bokashi (biochar-bokashi). The bokashi was produced from fermented rice (Oryza sativa L.) bran and was added to increase nutrients in the amendment. Half of the plants in each soil treatment were inoculated with Phytophthora cinnamomi Rands, which causes root rot in blueberry. Although pH of the raw biochar was high (8.5), soil pH averaged 4.5 to 5.5 in each treatment. In the absence of P. cinnamomi, plants grown with 20% biochar or 10% or 20% biochar-bokashi had greater leaf area and 30% to 70% more total dry weight than those grown with 10% biochar or in unamended soil. Biochar also improved soil aggregation and increased root colonization by ericoid mycorrhizal fungi. The percentage of roots colonized by mycorrhizal fungi was 54% to 94% in plants grown with the amendments, but was ≤10% in those grown in unamended soil. Plants inoculated with P. cinnamomi were stunted and showed typical symptoms of root rot. Root infection by the pathogen was unaffected by biochar or biochar-bokashi and negated any growth benefits of the amendments. Overall, amending soil with biochar appears to be a promising means of promoting plant growth and mycorrhizal colonization in blueberry, but it may not suppress phytophthora root rot.

“…Further studies done by Van Bruggen and Finckh [15] reported the beneficial effects of EM which include suppression of soil-borne pathogens, increased decomposition rate of organic waste, increased availability of mineralized nutrients to plants, enhancement of microbial activities, increased nitrogen fixation, and reduced requirement of chemical fertilizers, pesticides, and fungicides. Shin et al [5] added that EM helps to speed up the natural composting process, without many of the side effects of foul odours and pests. Figure 1 shows the function of EM in the soil-plant ecosystem which was illustrated by Higa [19].…”

“…Megir and Paulus [1] added that these microbes may not be able to withstand the intolerable pH, moisture, and temperature conditions of degraded soils. Hence, the proper and regular addition of organic amendments is often an important part of any strategy to ensure the survival of newly introduced microorganisms [5]. To this end, there is strong belief that Natural Farming can ensure very productive pepper farming, clean environment, increase profits of pepper growers, and at the same time make healthy and fresh organic produces affordable for everyone.…”

“…It is a natural agriculture alternative which promotes lower production cost and at the same time is able to achieve product of high quality and yield with lower or without the usage of inorganic fertilizers and pesticides [4]. As the approach is closely related to soil fertility, introducing Natural Farming to enhance the predominance of beneficial and effective microorganisms can help to improve and maintain soil biological, chemical, and physical properties (Fukuoka, 2009) [5].…”

This paper reviews the role of Natural Farming as an ecological farming method to produce organically grown food of safe and high quality and at the same time improve soil quality and soil health. Currently, there is a dearth of information on the effects of Natural Farming approach on black pepper farms particularly in Sarawak, Malaysia. Previous studies on other crops had indicated positive outcome using the Natural Farming method. Thus, this paper discusses the essential role of effective microorganisms in Natural Farming and their potential in pepper cultivation. Through the action of effective microorganisms, this approach should be able to transform a degraded soil ecosystem into one that is fertile and has high nutrients availability. The mixed culture of effective microorganisms applied must be mutually compatible and coexist with one another to ensure its favorable establishment and interaction in the soil. Therefore, it is anticipated that introducing Natural Farming in black pepper cultivation can enhance the predominance of effective microorganisms in the soil, which in turn could lead to promising growth and yield of the crop.

Um fertilizante orgânico que cada vez mais tem ganhado espaço na agricultura é o bokashi. O bokashi é resultante de um método de compostagem baseado na adição de solução líquida de microrganismos efetivos, que são bactérias anaeróbicas e fermentos do ácido láctico. Uma técnica do Japão que foi adaptada para o Brasil no final da década de 80 por imigrantes japoneses. No Brasil, ele é conhecido como “Fermento da Vida”, por trazer vida ao solo, aumentando o número e a diversidade dos microrganismos que vivem no mesmo. Nota-se que o conhecimento científico sobre o bokashi ainda não foi muito explorado, além disso, não se encontra na literatura uma pesquisa bibliográfica sobre este adubo orgânico. Neste contexto, objetivou-se nesta pesquisa, sistematizar os estudos realizados sobre bokashi nas áreas de agricultura e ciências biológicas, ciência ambiental, bioquímica, genética e biologia molecular, imunologia e microbiologia, engenharia química, energia, multidisciplinar, química, ciências sociais e veterinária. O presente trabalho foi realizado por meio do instrumento de pesquisa Periódico Capes, através das bases Scopus e Web Of Science (WOS). Para ambas as bases foram utilizadas as seguintes palavras chaves: bokashi; para baixar os documentos pesquisados foi utilizado o Software EndNote X7. A pesquisa foi realizada no dia 01 de julho de 2019. Por meio desta pesquisa de revisão pode-se concluir que mais de 50% dos artigos publicados sobre bokashi nos últimos 20 anos de pesquisas são voltados para a área de agricultura e ciências biológicas e ciências ambientais, demonstrando que outras áreas como veterinária, ciências sociais, química, multidisciplinar, energia, engenharia química, imunologia e microbiologia, bioquímica, genética e biologia molecular, são escassas em pesquisas relacionadas ao adubo.
