  • This study evaluated microbial risk that could develop within soil microbial communities after amended with organic fertilizers from stabilized swine manure waste. For this purpose, we assessed the occurrences and competitiveness of antibiotic resistance and pathogenicity in soil microbial communities that were amended with swine manure wastes stabilized by a traditional lagoon fermentation process and an autothermal thermophilic aerobic digestion process, respectively. According to laboratory cultivation detection analysis, soil applications of the stabilized organic fertilizers resulted in increases in absolute abundances of antibiotic resistant bacteria and of two tested pathogenic bacteria indicators. The increase in occurrences might be due to the overall growth of microbial communities by the supplement of nutrients from the fertilizers. Meanwhile, the soil applications were found to reduce competitiveness for various types of antibiotic resistant bacteria in the soil microbial communities, as indicated by the decrease in relative abundances (of total viable heterotrophic bacteria). However, competitiveness of pathogens in response to the fertilization was pathogens-specific, since the relative abundance of Staphylococcus was decreased by the soil applications, while the relative abundance of Salmonella was increased. Further testes revealed that no MAR (multiple antibiotic resistance) occurrence was detected among cultivated pathogen colonies. These findings suggest that microbial risk in the soil amended with the fertilizers may not be critical to public health. However, because of the increased occurrences of antibiotic resistance and pathogenicity resulted from the overall microbial growth by the nutrient supply from the fertilizers, potential microbial risk could not be completely ruled out in the organic-fertilized soil samples.

  • This study was conducted to investigate the effects of microbial fertilizers on the yields of chard, chemical components of plant and soil, and the microbial floras. Six microbial fertilizers, MPK+Husk+Palma, Husk+palma, MPK+Compost, Compost, Bio livestock cattle system (BLCS) cattle dropping, and Tomi, were used. The yield of chard in six microbial fertilizer treatments was higher than that of control. The BLCS cattle dropping treatment showed the highest yield of chard among six microbial fertilizer treatments. Only one component, MgO in chard was increased with all treatments compared with control, Two components, K and Mg, in soil were increased with Tomi treatment. The number of total bacteria and bacillus was increased in soil that treated with Tomi, Husk+palma, and MPK+Husk+Palma. The number of actinomycetes and fungi was also increased with Tomi treatment. It appears that the microbial fertilizers increase the yield of chard by forming the useful microbial floras.

  • Banana planting altered microbial communities and induced the enrichment of Fusarium oxysporum in rhizosphere compared with that of forest soil. Diseased plant rhizosphere soil (WR) harbored increased pathogen abundance and showed distinct microbial structures from healthy plant rhizosphere soil (HR). The enriched taxon of Bordetella and key taxon of Chaetomium together with some other taxa showed negative associations with pathogen in HR, indicating their importance in pathogen inhibition. Furthermore, a more stable microbiota was observed in HR than in WR. Taken together, the lower pathogen abundance, specific beneficial microbial taxa and stable microbiota contributed to disease suppression.

  • This study was carried out to investigate the effects of soil microbial fertilizers on yields of Chinese cabbage (Brassica campestris L.). Five microbial fertilizers, MPK+Husk+Palma, Husk+Palma, MPK+Compost, BLCS(Bio livestock cattle system) cattle dropping, and Tomi, were used. All of microbial fertilizers significantly increased yields of Chinese cabbage, except BLCS cattle dropping. MPK+Husk+Palma was the most effective than any other treatments. Chinese cabbage treated with Tomi showed higher concentrations of K, Ca, Mg, Fe, Mn, and Zn than Compost treatment. MPK+ Husk+Palma was high in concentrations of Mg and Mn. MPK+Compost was high in concentrations of K, Mg, and Na. In a chemical components of soil, concentrations of K and P was increased with Tomi treatment, however, the other concentrations of plant and soil chemical components were not different. In a microbial properties of soil, Tomi, Husk+Palma, and MPK+Husk+Palma treatments increased in the number of total bacteria and bacilli. Tomi treatment increased in the number of actinomycetes and fungi. The other microbial properties of soil showed no significant differences. It would be assumed that yield increase in Chinese cabbage might be due to the beneficial microbial properties, therefore, those would increase yields of Chinese cabbage.

  • The degradation of fungicide oxadixyl in soil amended with manure, chemical fertilizers, heavy metals and detergent was studied. The degradation of oxadixyl in the soil was slow, but became to be fast after the lag phase of about 14 days. The half-life was 10.5 days. The degradation rate was accelerated largely by the amendment of manure. Potassium also promoted the degradation rate but nitrogen and phosphate did not. The heavy metals inhibited the degradation rate, in order of Ni, Cd, Cr, Cu, and Zn. The degradation rate was declined greatly with the addition of synthetic detergent. The microbial biomass and the respiration rate in the soil were increased by the amendment of manure and chemical fertilizers, but decreased by the addition of heavy metals and cleaner. The degradation rate of oxadixyl was positively correlated with the microbial biomass and the respiration rate.

  • We conducted a survey of actual using conditions of farm-made liquid fertilizers by investigating their formulation types, materials, making processes, using methods and various beneficial effects on 29 farms certified by National Agricultural Products Quality Management Service to produce environment-friendly agricultural products in 2009. Most of the materials used to make liquid fertilizers are those that can be easily obtained around the farms. Molasses or black sugar are added as an energy source of microorganism. And leaf mold, bacterial cultures supplied by agricultural extension centers of local governments, and cultures of native microorganisms were used as microbial sources for fermenting effective microorganisms. Types of the farm-made liquid fertilizers were fermented liquid fertilizers, fermented plant juices, amino acid liquid fertilizers, calcium-liquid fertilizers, and phosphoric acid liquid fertilizers. Effects of liquid fertilizers used by the farms were found to promote plant growth by supplying nutrition, to accelerate blooming and flower bud formation, to enhance the quality of agricultural products such as increase of sugar contents and improvement of storing conditions, to induce resistance against diseases and insect pests, and to cause endurance to high temperature stress. Chemical properties of the liquid fertilizers collected were analyzed. As a result, pH and EC range showed differences according to kinds of the liquid fertilizers. Amount of macro-nutrients, such as nitrogen and phosphoric acid, in most of the collected liquid fertilizers, was found to be low. Even though the liquid fertilizers were made from same materials, their contents was found to be different depending on the making process.
