“…Fertilisers containing Bacillus spp. need more nitrogen in the soil to function (Sun et al 2020), so, in our experiment, a higher impact on the grass yield when we added fertilisers with high nitrogen or used fertilisation scheme A was confirmed.…”

For 2 years (2019–2020), a field experiment to test the activities of different fertilisation schemes on the yield, colour and health status of five different grass mixtures for football pitches was conducted. Two grass mixtures were composed of different varieties of perennial ryegrass, one mixture was composed of varieties of perennial ryegrass and Kentucky bluegrass, one mixture consisted of the species Lolium perenne, Festuca rubra, Festuca arundinacea and Poa pratensis, and the seeds of only one variety of perennial ryegrass were sowed in one plot. Three different fertilisation schemes were included in the experiment. The first scheme (A) contained an inorganic fertiliser with added soil improvers, the second scheme (B) included an organic fertiliser with added soil improvers and the third scheme (C) was composed of an inorganic fertiliser. According to this study, the grass yield largely depends on the soil temperature, amount of precipitation and soil water content, and the occurrence of the fungus Laetisaria fuciformis is influenced by the fertilisation scheme, as the % infection with the fungus was highest when organic fertilisers with low % nitrogen was used. The selection of fertilisers is seen as an important factor for the turfgrass colour.

“…The use of biofertilizer may shift the composition of the plant microbiome. Sun et al [ 31 ] reported that the application of B . subtilis biofertilizer reduced the abundance of ureC genes and increased the abundance of functional genes (bacterial amoA and comammox amoA ) and ammonia-oxidizing bacteria, suggesting that the conversion of fertilizer nitrogen to NH 4 + -N decreased, and the nitrification process increased.…”

Bacillus subtilis strain Ydj3 was applied to sweet peppers to understand the influence of this bacterium on the growth, fruit quality, and rhizosphere microbial composition of sweet pepper. The promotion of seed germination was observed for sweet pepper seeds treated with the Ydj3 strain, indicating that Ydj3 promoted seed germination and daily germination speed (131.5 ± 10.8 seeds/day) compared with the control (73.8 ± 2.5 seeds/day). Strain Ydj3 displayed chemotaxis toward root exudates from sweet pepper and could colonize the roots, which enhanced root hair growth. Following the one-per-month application of strain Ydj3 to sweet pepper grown in a commercial greenhouse, the yield, fruit weight, and vitamin C content significantly increased compared with those of the control. Additionally, the composition of the rhizosphere bacterial community of sweet pepper changed considerably, with the Bacillus genus becoming the most dominant bacterial genus in the treated group. These results suggested that B. subtilis Ydj3 promotes seed germination and enhances fruit quality, particularly the vitamin C content, of sweet pepper. These effects may be partly attributed to the B. subtilis Ydj3 colonization of sweet pepper roots due to Ydj3 chemotaxis toward root exudates, resulting in the modulation of the rhizosphere bacterial community.

“…Non‐toxic microorganisms can be utilized to prevent the potential threats of cyanobacteria toxins to ecosystem. To our knowledge, some microorganisms, including Rhodospirillum rubrum , Bacillus pumilus , and Bacillus subtilis , perform well in nitrogen fixation and have no toxic effects on plants and ecosystem 73–75 . Besides, Bacillus sp., which are widely spread in atmosphere, farmland, and water, will not cause biological invasion even if they enter into the soil and water via wastewater or irrigation water.…”

Soil degradation, overuse of chemical fertilizer, and biodiversity loss are serious problems challenging the sustainable development of modern agriculture. In recent years, owing to the advantages of algae biotechnology in nutrients recovery and soil improvement, the integration of algae‐based wastewater remediation and algal bio‐fertilizer production is emerging into the limelight. In this work, we emphasize on the progresses achieved in the fields of biomass production by algae cultivation in wastewater and application of algal bio‐fertilizers. Particularly, three types of algal bio‐fertilizers, including slow‐release bio‐fertilizer, nitrogen‐fixing cyanobacteria, and liquid bio‐fertilizer, widely evaluated and utilized in agriculture are introduced. To prevent the overly optimistic prediction of algal bio‐fertilizer in a real‐world application, we point out the challenges and technical defects, such as presence of new pollution factors in wastewater, high cost of algal biomass, contamination of algal biomass in wastewater, low productivity of algae and valuable components, high water consumption, and potential threats of cyanobacteria to the environment, that prevent the concept of integrating algae‐based wastewater remediation and algal bio‐fertilizer production from becoming a reality. Based on our knowledge and experience, potential solutions to the aforementioned problems are discussed in depth. It is expected that the emerging technologies of algae‐based wastewater remediation for bio‐fertilizer production will bring human beings into a new era of environmentally‐friendly, high‐yield, and resource‐recycling agriculture. © 2020 Society of Chemical Industry (SCI)
