“…Microbial inoculums called effective microorganisms (EM), containing mixed cultures of beneficial and naturally occurring microorganisms, can increase the microbial diversity of the soil ecosystem. They consist mainly of lactic acid bacteria, photosynthetic bacteria, yeast, Actinomyces, and fermenting fungi (Balogun et al, 2016). Among these effective microorganisms, PGPB form specific symbiotic relationships with plants and directly promote plant growth by facilitating resource acquisition and/or modulating plant hormone levels (Glick, 1995).…”

Modern agriculture has become heavily dependent on chemical fertilizers, which have caused environmental pollution and the loss of soil fertility and sustainability. Microalgae and plant growth-promoting bacteria (PGPB) have been identified as alternatives to chemical fertilizers for improving soil fertility. This is because of their biofertilizing properties, through the production of bioactive compounds (e.g., phytohormones, amino acids, and carotenoids) and their ability to inhibit plant pathogens. Although treatment based on a single species of microalgae or bacteria is commonly used in agriculture, there is growing experimental evidence suggesting that a symbiotic relationship between microalgae and bacteria synergistically affects each other’s physiological and metabolomic processes. Moreover, the co-culture/combination treatment of microalgae and bacteria is considered a promising approach in biotechnology for wastewater treatment and efficient biomass production, based on the advantage of the resulting synergistic effects. However, much remains unexplored regarding the microalgal–bacterial interactions for agricultural applications. In this review, we summarize the effects of microalgae and PGPB as biofertilizing agents on vegetable cultivation. Furthermore, we present the potential of the microalgae–PGPB co-culture/combination system for the environmentally compatible production of vegetables with improved quality.

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.

“…The higher (P<0.05) nitrogen content on the liquid fertilizer was along with the addition of molasses, this were due to the presence of nitrogen retained due to bacterial metabolism (nitrification) in addition to the results of manure N degradation (Widowati et al, 2014). Previous studies have shown that molasses' presence increases nitrifying bacteria's population ten times (Balogun et al, 2016).…”

Utilization of Different Concentration Sugarcane Molasses to the Quality of Goat Feces-Chicken Excreta-Coconut Husk Organic Liquid Fertilizer

Indonesia is an agricultural country that certainly has the potential for agricultural waste and by-products. Some of those in Indonesia are livestock manure, coconut husk, and sugarcane molasses. Utilization of this waste is limited, which is causing various environmental problems such as environmental pollution. The study is aimed to determine the quality of organic liquid fertilizer made by raw material from goat feces-chicken excreta-coconut husk with various sugarcane molasses concentrations (P0= 0%; P1= 5%; P3= 15%; P4= 20%; P5= 25%). The fermentation was carried out anaerobically for 21 days. The parameters of temperature, pH, organoleptic (color and odor), levels of C-organic, nitrogen (N) total, phosphorus (P) total, potassium (K) total, and biological tests were observed. Biological tests were conducted in the growth of mung bean (Vigna radiata) and spinach (Amaranthus tricolor). Data were analyzed using one-way ANOVA. Variations in the addition of molasses sugarcane did not affect the liquid fertilizer's temperature and pH during fermentation. However, the treatments had positive effect on organoleptic test, C-organic, N total, P total, K total, and biological tests. The addition of 15% sugarcane molasses (P3) showed a dominating performance toward most of the parameters tested. The P3 treatment produced liquid fertilizer with a pleasant smell, and the contents of C-organic, total N, total P, and total K were 2.12%, 0.25%, 0.13%, and 0.13%, respectively. and produce spinach as a biological test with plant height, number of leaves, leaf width, stem diameter, and root length were 21.82 cm, 6.66 sheets, 3.59 cm, 4.09 mm, and 14.67 cm, respectively.
