“…In our study, 6BC_60 and 4BC_60 treatments had a significant responses of growth. Unlike a single addition of organic amendment, which requires a greater amount of water, compost can supply nutrients and biochar can retain them in its pores to provide them to the plant which is in line with the finding of Vaughn et al [2018].…”

“…In comparison with our results, [Abideen et al, 2020] found that biochar improved photosynthetic activity and chlorophyll fluorescence. Vaughn et al [2018] reported that adding biochar and compost mixtures as an amendment for golf courses had the greatest fresh weights, dry weights, shoot heights of bentgrass compared to the 15% peat control. For 2B and 3B treatments, WUE revealed a certain increase in 100% and 80% water regimes.…”

The current study aimed to evaluate the effect of banana waste biochar on the physiological traits and growth of Paspalum vaginatum under three water treatments (100%, 80%, and 60% of the water holding capacity (WHC) of the soil). A plastic pot experiment was done for the germination of paspalum vaginatum. The treatments were the addition of compost, banana waste biochar, or banana waste biochar and compost combination to the soil. We used multiple factor analysis (MFA) to reveal the relationship between the effect of banana waste biochar and the three water regimes on physiological data. The findings revealed that banana waste biochar had an important impacts on all traits under various water supply conditions. The photon yield of PSII of control treatment at three water regimes had the lowest response compared to amended treatments. Changes were observed in chlorophyll pigment among different treatments.

“…Ain Najwa et al [91] also indicated that the fruit number and fresh weight of tomato in mixes with coco peat and 150 g biochar were higher than in mixes with oil palm fruit bunch (a newly developed organic medium) and 150 g biochar due to different physical and chemical properties of these two substrates. Vaughn et al [68] showed that creeping bentgrass (Agrostis stolonifera) had higher fresh and dry weight and shoot height in mixes with 85% sand, 10% anaerobic biosolids and 5% biochar (by vol.) than the one in mixes with 85% sand, 10% peat and 5% biochar (vol.…”

Biochar refers to a processed, carbon-rich material made from biomass. This article provides a brief summary on the effects of biochar on container substrate properties and plant growth. Biochar could be produced through pyrolysis, gasification, and hydrothermal carbonization of various feedstocks. Biochar produced through different production conditions and feedstocks affect its properties and how it performs when incorporated in container substrates. Biochar incorporation affects the physical and chemical properties of container substrates, including bulk density, total porosity, container capacity, nutrient availability, pH, electrical conductivity and cation exchange capacity. Biochar could also affect microbial activities. The effects of biochar incorporation on plant growth in container substrates depend on biochar properties, plant type, percentage of biochar applied and other container substrates components mixed with biochar. A review of the literature on the impact of biochar on container-grown plants without other factors (such as irrigation or fertilization rates) indicated that 77.3% of the studies found that certain percentages of biochar addition in container substrates promoted plant growth, and 50% of the studies revealed that plant growth decreased due to certain percentages of biochar incorporation. Most of the plants tested in these studies were herbaceous plants. More plant species should be tested for a broader assessment of the use of biochar. Toxic substances (heavy metals, polycyclic aromatic hydrocarbons and dioxin) in biochars used in container substrates has rarely been studied. Caution is needed when selecting feedstocks and setting up biochar production conditions, which might cause toxic contaminants in the biochar products that could have negative effects on plant growth.

“…Previous research using biosolids incorporated into urban garden soils generally improved soil physical and chemical properties (McIvor et al., 2012), although no data was presented for plant growth. Similarly, creeping bentgrass ( Agrostis stolonifera ) growth in simulated golf greens (containing 85% sand by volume) was greatest when grown with 10% biosolids; however, in this study the sand was not kept at saturated levels (Vaughn et al., 2018). From the results of our study, however, the use of either biosolids or pyrolyzed biosolids in water‐saturated soils would not be desirable.…”

Dredged Illinois River sand is nutrient poor and has low cation exchange capacity.Engineering this soil by adding amendments to increase nutrient retention may help sustain plant growth and absorb contaminants when the sand is used in bioslopes, bioswales, and rain gardens. The objectives of this study were to compare the physical and chemical properties of engineered soils derived from dredged Illinois River sand combined with mixtures of a locally produced compost, dried Class B biosolids from the Greater Peoria Sanitary District (GPSD), and pyrolyzed GPSD biosolids, and to study their effect on the growth of a grass mixture designed for chronically wet areas, such as bioslopes and/or bioswales along Illinois Department of Transportation (IDOT) highways. Dry and wet bulk densities of the soil mixtures increased with increasing levels of both biosolids and pyrolyzed biosolids. Soils containing higher levels of compost were linked to higher CEC, soluble salts, porosity, and soil moisture. Shoot and root lengths, and fresh and dry tissue mass were highest in mixtures containing the higher compost levels. These results indicate that the addition of compost to Illinois River sand may be required for adequate grass growth in these engineered soils saturated with water. The use of either biosolids or pyrolyzed biosolids as nutrient sources may need to be supplemented with compost for adequate plant growth.
