### Inoculum Preparation  
The microbial consortium was the same that [PERSON] et al. (2021) obtained from compost. The isolation of the microbial consortium was carried out from ten grams of soil fertilized by organic composite, chosen based on the humidity and colour characteristic of soil with a high content of organic matter as a result of microbial decomposition. The sample was placed in 500 mL of TSB medium (Triptone Soya Broth, Thermo Fisher Scientific, Waltham, MA, USA) for microbial growth for 15 h under agitation at 120 rpm and 30 \({}^{\circ}\)C. A 1.0 mL aliquot of this homogenized medium was inoculated into 50 mL tubes containing TSB medium. The tubes were then incubated for 15 h under shaking at 120 rpm at 30 \({}^{\circ}\)C. Several aliquots were then cryopreserved in TSB medium with 30% of glycerol.  
A cryopreserved sample was reactivated by inoculation in 100 mL of TSB and by maintaining the temperature at 30 \({}^{\circ}\)C for 72 h. Then, the reactivated culture was used to produce the inoculum for the experiment. An amount of 1 mL of the reactivated cells was transferred to several flasks containing 300 mL of TSB, which were incubated in static cultivation at 30 \({}^{\circ}\)C for 72 h to get the amount necessary for the treatments. The cell

concentration in the suspension was adjusted to get \(1.2\times 10^{9}\) cells/mL with the quantitative nephelometry test [29].  
The _Arthospira platensis_ strain BMAKD7 was obtained from the \"Aidar & Kutner Microorganism Bank of the Oceanographic Institute of the University of Sao Paulo\". The cyanobacteria were inoculated in 20 L of 1:5 diluted vermicompost tea in water without sterilisation. An amount of 2.5 g/L of NaNO\({}_{3}\) and 16 g/L of NaHCO\({}_{3}\) was added to the medium. A photobioreactor was assembled using an organizer box with 29 L of capacity. On the lid of the box, an 18 W LED lamp was attached, which was connected to a timer programmed for 12 h of light time per day. Considering the variations in luminosity in the laboratory and the different depths at which the cells were positioned inside the box, a variation from 1570 to 2500 lux was measured without the presence of culture media and cells, which influence light absorption. The range of luminosity obtained was within good conditions for establishing cell growth [30]. The aeration was controlled using a submersible pump (220 L/h, Elo Imports, Hong Kong, China) and the system worked for 14 days at room temperature for the cyanobacterial growing. For the field application, the cyanobacterial suspension was diluted in water in a proportion of 1:3 to give a 1:15 final dilution for the vermicompost tea and a concentration of 0.83 g/L of _A. platensis_.  
In the place destined to be a vegetable garden at the Obra Social Celio Lemos (OSCL) in Sao Jose dos Campos, SP, anrisanal Bokashi was utilised by the local farmer at the experimental site for the experiments. It used 45 kg of garden soil, 10 kg of rice straw, 4 kg of rice bran, 16 kg of manure, 1.4 kg of crushed coal, 800 g of yorin, and 400 g of phosphite. The ingredients were mixed with 10 L of a mixture of 5 L of the efficient microorganisms (E.M.) suspension, 5 kg of sugar cane molasses, and 100 L of water. E.M. were produced from samples of fungi isolated from Atlantic Forest litter in the region of Sao Jose dos Campos, using cooked rice as bait. After 7 days, the colonies grown on the cooked rice were selected by their colours: the dark ones were eliminated and the others were used as inoculum in a broth medium based on sugar cane molasses, milk, and rock dust.
