The plant-microbe holobiont has garnered considerable attention in recent years, highlighting its importance as an ecological unit. Similarly, manipulation of the microbial entities involved in the rhizospheric microbiome for sustainable agriculture has also been in the limelight, generating several commercial bioformulations to enhance crop yield and pest resistance. These bioformulations were termed biofertilizers, with the consistent existence and evolution of different types. However, an emerging area of interest has recently focused on the application of these microorganisms for waste valorization and the production of “bio-organic” fertilizers as a result. In this study, we performed a bibliometric analysis and systematic review of the literature retrieved from Scopus and Web of Science to determine the type of microbial inoculants used for the bioconversion of waste into “bio-organic” fertilizers. The Bacillus, Acidothiobacillus species, cyanobacterial biomass species, Aspergillus sp. and Trichoderma sp. were identified to be consistently used for the recovery of nutrients and bioconversion of wastes used for the promotion of plant growth. Cyanobacterial strains were used predominantly for wastewater treatment, while Bacillus, Acidothiobacillus, and Aspergillus were used on a wide variety of wastes such as sawdust, agricultural waste, poultry bone meal, crustacean shell waste, food waste, and wastewater treatment plant (WWTP) sewage sludge ash. Several bioconversion strategies were observed such as submerged fermentation, solid-state fermentation, aerobic composting, granulation with microbiological activation, and biodegradation. Diverse groups of microorganisms (bacteria and fungi) with different enzymatic functionalities such as chitinolysis, lignocellulolytic, and proteolysis, in addition to their plant growth promoting properties being explored as a consortium for application as an inoculum waste bioconversion to fertilizers. Combining the efficiency of such functional and compatible microbial species for efficient bioconversion as well as higher plant growth and crop yield is an enticing opportunity for “bio-organic” fertilizer research.

Aggregation and dynamics of soil organic matter under different management systems in the Brazilian Cerrado

et al. 2021

View full text Add to dashboard Cite

The objectives of this study were to evaluate the stability of aggregates, and quantify the contents and stocks of total organic carbon (TOC), and granulometric and humic fractions of soil organic matter (SOM). Four management systems were evaluated: (1) a no-tillage system (NTS) implemented 5 years ago (NTS5); (2) NTS implemented 17 years ago (NTS17); (3) conventional tillage system (CTS) implemented 20 years ago (CTS20); and (4) native Cerrado vegetation. For each system, five undeformed and five deformed soil samples were collected from the 0.00–0.05, 0.05–0.10, 0.10–0.20, and 0.20–0.40 m layers. The weighted mean diameter (WMD), TOC, stock of carbon (StockC), organic carbon particulate (OCp), organic carbon associated with minerals (OCam), stock of OCp, stock of OCam, carbon stock index, carbon management index (CMI), organic carbon in the fulvic acid fraction (FAF), humic acid fraction (HAF), and humin fraction were quantified. The WMD and CMI values increased as the soil management intensity decreased. The adoption of the NTS increased the WMD and the contents, stocks, and proportions of TOC in the more labile granulometric and humic (FAF/HAF) fractions of the SOM. The WMD, CMI, granulometric and chemical fractionation of the SOM were more efficient than the TOC and StockC in identifying the differences between the management systems. Due to the higher contents of the more labile fractions of SOM, the granulometric and chemical fractionation of SOM in the NTS5 and NTS17 systems had higher values of WMD and CMI than the CTS20 system.

Effect of L-Tryptophan and L-Glutamic Acid on Carrot Yield and Its Quality

et al. 2023

View full text Add to dashboard Cite

Positively affecting crop quality and yields, amino acids used as plant stimulants play a special role in ensuring global food security. L-tryptophan (L-Try) and L-glutamic acid (L-Glu) are important biostimulants that increase the yield of field crops and vegetables. Carrot is one of the most important vegetables due to its production volume in the world (sixth most consumed vegetable) and its nutritional value. The response of different plant species to amino acid application varies. The literature mainly deals with the effects of ready-made products containing a mixture of several amino acids, with no exhaustive studies on the effects of individual amino acids on carrot quality and yield. This paper is based on a two-year field experiment (2019–2020), in which the effect of two amino acids, L-Trp (7.5 g·ha−1) and L-Glu (60.0 g·ha−1), on carrot (Daucus carota L.) was investigated. They were applied to the leaves (FA) or both to the soil and to the leaves (S + FA), separately, (L-Trp or L-Glu) or as a mixture (L-Trp + L-Glu). The control plot was treated with mineral fertilizers only. The research was conducted as a field experiment in a split-block design. The yield of carrot storage roots and their content of dry matter, protein, sugars, total soluble solids (TSS), and ascorbic acid were determined. The amino acids positively affected the yield of carrots compared to the control, but only the synergistic action of L-tryptophan and L-glutamic acid increased it significantly. On average, for both amino acids the S + FA application increased the protein content and the marketable yield of storage roots significantly more than in response to FA treatment. A significant increase in marketable yield compared to the control was found after the combined soil and foliar application (S + FA) of all amino acid combinations, but the L-Trp + L-Glu mixture worked best. The storage roots of carrots grown on the plot with L-Trp + L-Glu contained significantly more protein and TSS than those on the control plot. The content of TSS was also positively affected by L-Trp used on its own, while L-Glu increased the content of ascorbic acid. Amino acids applied to the leaves (FA) increased the content of total sugars in the carrot roots more than when applied both to the soil and to the leaves (S + FA). Of all treatment combinations, the synergistic action of L-Trp and L-Glu made it possible to obtain the highest yields of carrot storage roots, containing the most protein and total soluble solids.
