“…The idea of extensive aerobic microbial pre-processing of organic extracts before incorporating them in the hydroponic systems was first studied in the 1990s by the same searchers who explored bioponics in space habitats [130][131][132]134,135,137] after these authors observed the shortcomings of using raw organic material extracts for plant growth. The process consisted of the loading of dried crop residues in an aerobic bioreactor with continuous stirring, in which the pH and dissolved oxygen (DO) were controlled [135].…”

Hydroponics is a soilless cultivation technique in which plants are grown in a nutrient solution typically made from mineral fertilizers. This alternative to soil farming can be advantageous in terms of nutrient and water use efficiency, plant pest management, and space use. However, developing methods to produce nutrient solutions based on local organic materials is crucial to include hydroponics within a perspective of sustainability. They would also allow hydroponics to be developed in any context, even in remote areas or regions that do not have access to commercial fertilizers. This emerging organic form of hydroponics, which can be qualified as “bioponics”, typically recycles organic waste into a nutrient-rich solution that can be used for plant growth. Many methods have been developed and tested in the past three decades, leading to greatly heterogenous results in terms of plant yield and quality. This review describes the main organic materials used to produce nutrient solutions and characterizes and categorizes the different types of methods. Four main categories emerged: a “tea”-type method, an aerobic microbial degradation method, an anaerobic digestion method, and a combined anaerobic-aerobic degradation method. The advantages and drawbacks of each technique are discussed, as well as potential lines of improvement. This aims at better understanding the links between agronomic results and the main biochemical processes involved during the production, as well as discussing the most suitable method for certain plants and/or contexts.

“…From 1st to 5th day, the concentration of NH 4 -N was relatively high, due to the addition of the effluent. After the 5th day, NO 2 -N increased following by the increase of NO 3 -N. After the 20th day, most of the inorganic nitrogen had been transformed into NO 3 -N. This suggested that the microbial nitrification was done, because most of crops prefer nitrate than ammonia [3]. By contrast, the pH in nutrient solution was increased in association with increasing of NH 4 -N, and decreased with increasing of NO 3 -N concentration (FIGURE 3).…”

“…Thus, it is possible to hypothesize the effects on soil-less system with decreased amount of P as using of effective microorganisms in such system could lead a more sustainable management. This study was conducted to evaluate the effect of different concentrations of P in the nutrient solution on the yield of tomatoes grown hydroponically using the Kurojiru and Fulvic acid [14][15].…”

Soil-less system constitutes an efficient approach for the cultivation of tomato; however, organic liquid amendments are very limited under such systems. The current experiment aimed to evaluate the effects of Kurojiru (K), an organic liquid fertilizer and fulvic acid (FA) on the growth and production of tomato, Solanum lycopersicum L. cv. ‘Momotaro’. Recently, it is desirable to reduce the environmental impact and fertilizer cost by lowering the concentration of inorganic components in the culture medium. Therefore, we explored the effect of adding these organic fertilizers on the yield and quality of tomatoes by gradually reducing the phosphoric acid concentration in the culture medium (87, 58 and 29 mmol・pot-1・week-1). The whole experiment was conducted for 20 weeks (from seeding until harvesting). The plant biomass, tomato fruit weight and chlorophyll content were measured. The fresh weight (FW) of both root and shoot indicated a progress response according to phosphorus concentration in liquid media, in FA treatments. Total fresh weight was significantly higher in the treatment with K+FA than in the control. Additionally, the yield responded to the all treatments within the 58 mmol P. Especially, in this level of P the relative fruit weight was higher only under K application. The chlorophyll content responded K+FA treatment under a low P content (29 mmol), and to all of those in 58 mmol. These results indicate that Kurojiru has some positive effects on tomato growth in soil-less systems.
