Bokashi as an Amendment and Source of Nitrogen in Sustainable Agricultural Systems: a Review.

Abstract

Integral soil fertility is managed by practices that contribute to organic matter, which improves its properties. Bokashi is an organic amendment that can be part of the tools used in sustainable soil management. This review systematizes existing information regarding the production and use of bokashi. In addition to discussing guidelines for the production and use of good-quality bokashi, it also focuses on the availability of N and microbial aspects, using compost as a reference amendment. Through this review, it was also found that (1) in order to obtain bokashi with a high N content, raw materials with a high N content must be used and, the dose of the initial C source of easy microbial assimilation should be increased. (2) Regarding the acceleration of the mineralization of the organic matter produced by the microbial inoculum, contradictory results have been obtained. Therefore, a better understanding of the interactions between the microorganisms that constitute the inoculum and the principle native microbial groups is required. (3) Few studies have evaluated the relationships between the N availability of bokashi, yield, and crop characteristics, as well as how bokashi could contribute to the fertility and availability of N when included in combination with other cultural practices.

De potentie voor koolstofvastlegging in Gelderse landbouwbodems

“…plantenresten van de landbouw, bermmaaisel en gft-afval (Olle, 2021). Bokashi lijkt veel op compost, het heeft ook een hoog organischestof-en nutriëntengehalte (Quiroz and Céspedes, 2019). Omdat er zoveel verschillende inputmaterialen gebruikt kunnen worden, is bokashi erg verschillend van kwaliteit (Quiroz and Céspedes, 2019).…”

Omdat er zoveel verschillende inputmaterialen gebruikt kunnen worden, is bokashi erg verschillend van kwaliteit (Quiroz and Céspedes, 2019). Zo heeft bokashi gemaakt van gft-afval bijvoorbeeld een hoger gehalte aan nutriënten dan bokashi gemaakt van bermmaaisel (Romkens et al, 2020).…”

Farmer experiences of Tiyeni’s ‘deep-bed farming’ conservation agriculture system in Malawi

“…Bokashi, meaning 'fermented organic matter', derives from traditional Japanese composting methods that involve the mixing of food waste with soils, with the key ingredient being 'efficient microorganisms' (yeasts and bacteria) which aid fermentation and the production of rich soil nutrients. Research has shown that in many cases bokashi manure can produce the same increases in soil fertility and crop production as artificial fertilisers (Xiaohou et al 2008;Quiroz and Cespedes, 2019). Because it uses local waste products found in and around the farm (crop residues, animal manure, ash, maize bran) bokashi manure is both environmentally friendly and low-cost.…”

Bokashi, Boiled Manure and Penergetic Applications Increased Agronomic Production Variables and May Enhance Powdery Mildew Severity of Organic Tomato Plants

“…However, for arugula (Eruca sativa L.) and radish (Raphanus sativus L.), higher yields have been achieved with 10% and 5% BM, respectively [2]. Effective microorganism (EM) Bokashi is a well-known soil amendment used in agriculture [3,4], and has been tested with promising results for tomato [5,6], arugula [2], radish [2], and lettuce (Lactuca sativa L.) [7]. Based on 130 long-term experiments, organic amendments provided stability in plant and fruit production, and may increase yield by up to 15% in tropical conditions [8].…”
