“…At harvesting, application of chemical fertilizer alone showed lower microbial count for bacterial group compared to inoculated ones. The results corroborate with the finding of Mandic et al (2011) and Javoreková et al (2015) who reported that the application of biofertilizers alone with organic manures resulted in enhanced microbial activity. Nutrient status of soil: At the time of transplanting N level in soil was140 kg ha -1 , P level was 32 kg ha -1 and K level was 150 kg ha -1 .…”

Biofertilizers improves the soil microbial content, Soil nutrient status and nutrient uptake by plant. In an experiment, fifteen treatments comprised of various combinations of biofertilizers, organic manures and chemical fertilizers were compared to access the impact of different sources of nutrient on performance of onion. The highest soil organic carbon (0.40%) was observed in the treatments T12 (Farm Yard Manure (FYM) @ 20 t/ha) and T11 (FYM myctes count (29.9 X 104) was recorded in T11 (FYM @ 20 t/ha + Azotobacter + VAM) treatment while highest fungal @ 20 t/ha + Azotobacter + Vesicular-Arbuscular Mycorrhizae (VAM)). Highest bacterial (24.5 X 106) and actino-count (17.5 X 103) was observed in T3 (Azospirillium+ Recommended dose of NPK) treatment. At the time of harvesting, available nitrogen (N), available phosphorus (P) and available potassium (K) were higher in treatment T3 (Azospirillium + Recommended dose of NPK), T9 (Azotobacter+ VAM + Recommended dose of NPK) and T13 (Poultry treatment (162.6 Kg ha-1) as compared to all other treatments except T1 and T9 treatments while P uptake (13.6 Kg ha-Manure @ 5t/ha) treatments respectively than that in other treatments. Azospirillum and Azotobacter application along with recommended dose of N, P and K improved the fertility status of soil. The N uptake was significantly higher in T3 treatments. The present study highlights the need of use of biofertilizers along with organic and inorganic 1) was significantly higher in T9 treatment than that in other treatments except T1, T3, T5 and T7 treatments. The K uptake was significantly higher in T3 treatment (126.9 Kg ha-1) as compare to all other treatments except T1 and T9 manures/fertilizer to enhance the nutrient availability and improve soil health.

“…Soil physical data showed an increase in the total moisture content of the samples after treatment with microorganisms, which may be related to aerobic respiration: water and energy produced from substrates and oxygen and carbon dioxide released (Griffin 1996). The pH values found in experimental soil samples (pH 6.5-7.0) were suitable for optimal growth of microorganisms (Fierer et al 2005).…”

“…However, the addition of microorganisms other than B. cinerea has been found to increase the ability of soil microbial populations to utilize carbohydrates and complex carbon compounds. The method does not distinguish between who does it, added microorganisms or indigenous soil populations stimulated by interspecies interactions (Javorekova et al 2015). .…”

Purpose The manipulation of soil microbiota can involve changes in microbial diversity and microbial activities, and it is carried out for practical purposes. The microbial diversity can be modified by the inoculation of beneficial microorganisms into soil or by agricultural management practices. This study provides information on the influence of introducing beneficial soil microorganisms on soil indigenous microbiota. The aim of this study was to determine how biocontrol and plant growth promoting agents Trichoderma asperellum and Bacillus subtilis and their consortium affect indigenous soil microbiota without placing emphasis on the plant as a determinant of change. Methods Experimental soil samples were treated with B. subtilis and T. asperellum and their consortium. The shift of number of bacterial and fungal CFUs in soil was determined. Biolog EcoPlate assay demonstrated the metabolic activity of microorganisms in soil. The concentration of Trichoderma genus, Firmicutes, Gammaproteobacteria and Acidobacteria DNA in soil samples was determined by molecular methods. A correlation analysis was performed between microbiological and molecular data. Results Soil treatment with T. asperellum, B. subtilis and the plant pathogenic fungus Botrytis cinerea changed the number of CFUs and amplified DNA fragments of certain taxa. The study showed that added microorganisms did not significantly affect the metabolic diversity of the community and Shannon-Wiener biodiversity index but change the utilization of carbohydrates, complex carbon compounds and organic phosphorus compounds. Conclusion Introduced biocontrol and plant growth promoting agents T. asperellum and B. subtilis survive in soil during a 60-day experiment and influence composition and functionality of indigenous populations. Whereas B. subtilis and T. asperellum and their consortium are inhibitors of the pathogenic fungus B. cinerea, this could further positively affect specific crops.

“…Biofertilisers amended with inorganic fertiliser are used to increase nutrient availability to plant and can also affect the soil microbial biodiversity (Javoreková et al, 2015). Generally, the microbial consortium includes plant growth promoting rhizobacteria, nitrogen fixing bacteria, plant disease suppressive bacteria and fungi, soil toxicant degrading microbes, actinomycetes which are the increase in the vegetative growth of the OPS was due to the uptake of N from the soil as this nutrient is responsible for chlorophyll content and it is also vital for synthesis of food material in plants (Fraile et al, 2015).…”

Extensive use of inorganic substances contained in chemical fertilisers leads to environmental pollution and makes the plant more susceptible to diseases. The utilisation of beneficial microbes in biofertilisers has become a key solution in reducing the usage amount of chemical fertilisers in agriculture. This study was conducted on oil palm seedlings (OPS) in a nursery and treated with biofertiliser with zero chemicals (BF0), biofertiliser containing two percentage levels of chemical fertiliser (CF) (BF + 40% CF and BF + 50% CF) and two controls consisting of 100% chemical (CF100) and standard organic (SO) fertiliser. The vegetative measurements and foliar nutrients analysis for the OPS were recorded three and five months after fertilisation (MAF), when the OPS were six and eight months old, respectively. The application of biofertilisers containing low CF rates resulted in higher vegetative measurements compared to application of 100% chemical. Nutrients analysis showed that application of biofertiliser assisted in the increase of essential nutrients uptake in the OPS. Thus, we concluded that combination of biofertiliser with small rates of chemical able to increase vegetative measurements and nutrients uptake. Biofertiliser application is also capable in reducing the sole use of 100% chemical fertilisers, which is not environmental-friendly and expensive.
