“…This result implies that using digestate-enriched biochar resulted in a more complete recycle of a wide variety of nutrients compared to artificial fertilizers. Previous studies [54,62,66] corroborate this finding, it has been reported that the application of biochar adds a variety of nutrients compared to pure mineral fertilizers. Previous studies have also reported an antagonistic relationship between Ca and K, i.e., an increase in the concentration of potassium often limits the uptake of calcium [67].…”

Recycling and value-added utilization of agricultural residues through combining technologies such as anaerobic digestion and pyrolysis could double the recoverable energy, close the nutrient recycle loop, and ensure cleaner agricultural production. This study assessed the beneficial application of biochar to soil to recycle digestate nutrients, improve soil quality, and reduce conventional chemical fertilizer. The addition of digestate-enriched biochar improved soil quality as it provided higher soil organic matter (232%–514%) and macronutrients (110%–230%) as opposed to the unenriched biochar and control treatments. Maize grown in soil amended with digestate-enriched biochar showed a significantly higher biomass yield compared to the control and non-enriched biochar treatments but was slightly lower than yields from chemical fertilizer treatments. The slightly lower yield (20%–25%) achieved from digestate-enriched biochar was attributed to slower mineralization and release of the adsorbed nutrients in the short term. However, digestate-enriched biochar could in the long term become more beneficial in sustaining soil fertility through maintaining high soil organic matter and the gradual release of micronutrients compared to conventional chemical fertilizer. Positive effects on soil micronutrients, macronutrients, organic matter, and biomass yield indicates that enriched biochar could partly replace chemical fertilizers and promote organic farming in a circular economy concept.

“…The woodchips derived biochar demonstrated nitrogen content of 0.83% (TN), total organic carbon of 75.3% (TOC), ratio C/N of 231, pH of 7.4, conductivity 183 µS (EC), ash content 3.95%, moisture content 4.26% (MC). The content of chemical elements was as follows: total P (TP) 0.054% (TP), Mg of 680 mg kg −1 , Hg of 0.011 mg kg −1 , Zn of 75.4 mg kg −1 , Cd of 0.368 mg kg −1 , Pb of 1.65 mg kg −1 [20].

Increased fish pond production is associated with the generation of various waste including fish pond sediments. Fish pond sediments could be a valuable source of nutrients for growing plants, however they require further processing in order to be applied to soil. Composting is considered one of the methods for processing fish pond sediments. The aim of this work was to investigate the potential of organic fish pond sediments to be managed through laboratory composting with selected waste materials and evaluate the fertilizing potential of the obtained compost. The scope included: (1) analysis of organic fish pond sediments, (2) laboratory composting of organic fish pond sediments with wheat straw and green grass, (3) analysis of the obtained composts, (4) preparation of growing media with selected additives, (5) analysis of the properties of the prepared growing media and (6) analysis of the effect of the investigated growing media on the growth of Phaseolus vulgaris L. in pot experiments. The addition of cardboard waste and woodchips derived biochar to the obtained compost improved significantly the growth of the roots of Cardamine L. Also, the content of carbon and nitrogen in the compost mixtures increased. The addition of M1 (compost from organic fish pond sediments and 1% of biochar) to the soil had a significant impact on the growth of white beans.

“…The feedstock was cut into fine particles (<4 mm) to minimize heat transfer differences and heated in a reactor from room temperature to 400 o C at a rate of 10 o C min -1 under a nitrogen flow of 200 mL min -1 ; then the temperature was maintained at 400 o C for 2 h. Prior to carbonization, the feedstock was dried at 105°C overnight in an oven. The biochar was then cooled down to room temperature in the absence of air and the obtained particles were sieved to obtain <0.4 mm particles [32].…”

Biochar is an efficient soil amendment used for promoting plant resistance to heavy metal (HM)-contaminated soils. There is a need for further investigation of its impacts on plants and soil. This study was undertaken as a pot experiment to assess the effect of biochar (0, 2.5, and 5% mass fractions) on the morphological, physiological and biochemical responses of white willow seedlings (Salix alba L.) cultured in uncontaminated soil and mixed soil contaminated with HM (Cu, Pb, and Cd). Additionally, some chemical properties and HM bioavailability were evaluated. Biochar increased height and diameter, root elongation, leaf area and dry biomass of the seedlings in both soils. Its addition to the contaminated soil reduced electrolyte leakage, the malondialdehyde and proline contents but increased the chlorophyll content, net photosynthesis rate, intercellular CO 2 concentration and transpiration rate in the leaf. Use of biochar (especially at 5% rate) in both soils, increased soil pH, total nitrogen, soil organic carbon and available P and K, while in the contaminated soil the availability of Cu, Pb, and Cd decreased. The results showed that biochar is a suitable amendment to contaminated soils that improves plant properties by improving soil chemical features and immobilizing HMs.Abbreviations: Brunauer-Emmett-Teller (BET); Barrett-Joyner-Halenda (BJH); intercellular CO 2 concentration (Ci); transpiration rate (E); electrolyte leakage (El); stomatal conductance (Gs); leaf area (LA); heavy metal (HM); malondialdehyde (MDA); total nitrogen (TN); scanning electron microscopy (SEM); specific leaf area (SLA); soil organic carbon (SOC); water use efficiency (WUE) Arch Biol Sci. 2019;71(2):281-291 https://doi.
