“…These low concentrations of essential nutrients are less of a problem for leafy vegetables, such as lettuce (Pantanella et al, 2012 ; Delaide et al, 2016 ), but can restrict the yield potential for larger plants, such as tomato, which have a longer production season. Tomato productivity was similar to mineral one when using organic fertilizer in soil (Mitchell et al, 2007 ; Antonious et al, 2019 ) and short-term hydroponic cultivation (Shinohara et al, 2011 ). However, only this study compares tomato productivity in soilless hydroponics in long-term cultivation.…”

Generally, tomato plants cultivated organically (e.g., in organic waste or manure) have comparable (Verheul, 2005;Mitchell et al, 2007;Shinohara et al, 2011;Antonious et al, 2019) or slightly lower (Zhai et al, 2009) yields than plants cultivated with conventional fertilizer. However, reductions in fruit size have often been reported (Oliveira et al, 2013;Zhang et al, 2016).…”

“…In other crops, organic fertilization may increase root development, for example, citrus trees grown in soil (Martinez-Alcantara et al, 2016 ), maize seedlings (Canellas et al, 2002 ; Jindo et al, 2012 ), and lettuce in hydroponic culture (Shinohara et al, 2011 ).

Organic Waste-Based Fertilizer in Hydroponics Increases Tomato Fruit Size but Reduces Fruit Quality

In regions with intensive agricultural production, large amounts of organic waste are produced by livestock animals. Liquid digestate from manure-based biogas production could potentially serve as fertilizer if integrated with closed horticultural irrigation systems. The aim of this experiment was to investigate how fertilizer based on liquid biogas by-products of pig manure digestion can affect the growth and production of tomato plants. Integration of a nitrification bioreactor presumes a significantly lower concentration of nutrient solutions and a higher level of oxygenation than classical mineral cultivation. Therefore, additional controls were included. We compared plant growth and fruit quality traits of tomato plants grown in a hydroponic solution with organic fertilizer with two levels of mineral fertilizer. The tomatoes grown with organic waste-based liquid fertilizer showed reduced growth rates but increased mean fruit size, resulting in no significant change in total yield compared with high-mineral cultivation. The growth rate was similarly reduced in plants cultivated with low-mineral fertilizer. Plants cultivated with organic waste-based fertilizer had high Cl− concentration in xylem sap, leaves, and, ultimately, fruits. The leaves of plants cultivated with organic waste-based fertilizer contained higher concentrations of starch and soluble carbohydrate and low concentrations of phosphorous (P) and sulfur (S). The plants grown with organic waste-based or low-mineral medium showed significantly poorer fruit quality than the plants cultivated with the high-mineral solution. The low-mineral treatment increased xylem sap contribution to fruit weight because of higher root power. The organic waste-based fertilization did not change the root power but increased fruit size. In conclusion, organic waste-based cultivation is a possible solution for sustainable plant production in greenhouses. However, additional adjustment of nutrient supply is required to improve fruit quality.

“…In fact, many microorganisms multiplied and others were removed, due to a trace metal contamination, which resulted in shifts in the quality and functionality of soils. The potential for using recycled biosolids in agricultural production systems by adding lime (calcium carbonate) [45] or biochar [46] has been successful, due to their impacts on increasing soil pH and reducing trace metals availability to edible plants. Biosolids such as SS increased soil water retention, soil water holding capacity, and crop yield [2].…”

Soil enzymes (urease, invertase, acid and alkaline phosphatase) activity in the rhizosphere of field-grown tomato plants were used to monitor the impact of soil amendments (SA) and SA mixed with biochar on soil microbial activity four months after addition of amendments. The soil treatments were sewage sludge (SS); horse manure (HM); chicken manure (CM); vermicompost (worm castings); commercial inorganic fertilizer; commercial organic fertilizer; and no-mulch (NM) native soil used for comparison purposes. Soil treatments also were mixed with 10% (w/w) biochar to investigate the impact of biochar on soil enzymes activity. The results showed a significant increase in soil urease and invertase activities after incorporation of SA to native soil. Vermicompost and HM were superior in increasing urease and invertase activity four months after their addition to native soil. Alkaline phosphatase activity fluctuated among the soil treatments, revealing some obstruction of its activity. SS amended with biochar increased acid phosphatase activity by 115% four months after SS addition. Other than alkaline phosphatase, organic manure enhanced soil biological activity (microbial biomass and release of enzymes), indicating that the use of manures, rather than inorganic fertilizers, in crop production is an affordable and sustainable agricultural production system.

“…In the current study, the addition of PLB as a soil amendment increased the pH and EC of aridic calcareous soil (p < 0.05). The increases in soil pH and EC have been frequently reported in pot or field studies involving the addition of biochar sourced from a variety of feedstocks [45][46][47]49,55,56] or plant leaves [57]. Biochar-driven increases in soil pH, EC, and nutrient retention have also been reported in aridisols (mixed haplocambids) when applied with switchgrass biochar soil amendment.…”

Pongamia pinnata L. Leaves Biochar Increased Growth and Pigments Syntheses in Pisum sativum L. Exposed to Nutritional Stress

Pea (Pisum sativum L.) leaf chlorophyll and pigments syntheses are retarded under nutritional stress. Biochar has the potential to regulate soil nutrient supplies and optimize plant nutrient uptakes. We examine the role of Pongamia pinnata L. waste leaf biochar (PLB) in improving vegetative growth and leaf chlorophyll and accessory pigments of pea exposed to nutritional stress. Three PLB application rates (0, 1, and 2%) crossed with half (HF), and full NPK fertilizer (FF) recommended doses were applied to sandy soil field-pots (arranged in a completely randomized design). There were significant or maximum increases in plant vegetative or physiological traits, including the fresh or dry, above- and below-ground biomass weights, and photosynthetic pigments (chlorophyll a, chlorophyll b, total chlorophyll, carotenoids, and anthocyanin) in response to a 2%PLB + FF application (p = 0.002). Trait values also responded to 2%PLB + HF, which signified the nutrient regulatory character of PLB (p = 0.038). The PLB-driven reduction in nutritional stress resulted in diminished lycopene (antioxidant) content (p = 0.041). Therefore, we suggest that the soil application of 2%PLB + FF has the greatest impact on pea vegetative growth and leaf chlorophyll, carotenoids, anthocyanin, and lycopene contents in Pisum sativum L. Further research is recommended to investigate the relationship of PLB with soil nutrient availabilities and plant nutrient concentrations.
