“…A species-specific allometric equation was applied to estimate area/leaf, and sum these estimates across all leaves. For A. theophrasti, the equation described in Thomas et al [57] was used: A = 0.6519 × L 1.9523 , where A is leaf area in cm 2 and L is leaf length in cm. An allometric equation was developed for S. purpurea following the methods described in Thomas et al [57]:…”

“…Soil pyrogenic carbon provides numerous services to plants, sorbing many growth-inhibitory compounds (e.g., phenolics, salts, metals) [1,2], basifying acidified soils concomitant with improving nutrient retention and exchange [3], delivering a pulse of water-soluble elements available for plants and soil fauna [4,5], and improving soil water holding capacity [6]. When charcoal is applied as a soil amendment, the term "biochar" (BC) is used [7].…”

Is There a Positive Synergistic Effect of Biochar and Compost Soil Amendments on Plant Growth and Physiological Performance?

Abstract:The combination of biochar (BC) with compost has been suggested to be a promising strategy to promote plant growth and performance, but although "synergistic" effects have been stated to occur, full-factorial experiments are few, and explicit tests for synergism are lacking. We tested the hypothesis that a combination of BC and spent mushroom substrate (SMS) has a positive synergistic effect on plant growth and physiological performance in a nutrient-limited growing media. A greenhouse experiment with a full factorial design was conducted using mixed-wood BC (3.0 kg·m −2 ) and SMS (1.5 kg·m −2 ) (the combination was not co-composted) as organic soil amendments for the annual Abutilon theophrasti and the perennial Salix purpurea. Several measurements related to plant growth and physiological performance were taken throughout the experiment. Contrary to the hypothesis, we found that the combination of BC + SMS had neutral or antagonistic interactive effects on many plant growth traits. Antagonistic effects were found on maximum leaf area, above-and belowground biomass, reproductive allocation, maximum plant height, chlorophyll fluorescence, and stomatal conductance of A. theophrasti. The effect on S. purpurea was mostly neutral. We conclude that the generalization that BC and compost have synergistic effects on plant performance is not supported.

“…It typically contains 40-75% carbon (C), characterized by porous structure, large surface area, and high ion exchange capacity (Lehmann and Joseph, 2009). Application of biochar to saline soils will help to improve soil nutrient content (de la Rosa et al, 2014;Tian et al, 2016), enhance water retentionfertilizer conservation capacity (Gray et al, 2014;El-Naggar et al, 2015;Bass et al, 2016), and promote crop growth (Lashari et al, 2013;Liu et al, 2014;Agegnehu et al, 2016).…”

• Cumulative C min increases with biochar added and incubation temperature.• The temperature rise reduced the turnover time of C pools and Q 10 . This study assessed the effects of temperature and moisture on carbon mineralization (C min ) in a saline soil system with biochar amendment. The dynamics of C min were monitored in a biochar-amended saline soil for 220 days by incubation experiments under different conditions of temperature (15°C, 25°C and 35°C) and moisture (30%, 70% and 105% of the water-holding capacity). Results showed that as the incubation temperature rose, cumulative C min consistently increased in soil added with 0-4% biochar. The two-compartment model could well describe the dynamics of C min . The temperature rise increased the concentration of labile C in soil, but reduced the turnover time of labile and recalcitrant C pools and the value of temperature coefficient Q 10 . The response of C min to moisture was varying in soil amended with different levels of biochar. In the control treatment (soil alone), cumulative C min increased only when soil moisture was N105%. In the biochar treatments, however, 70% of waterholding capacity was optimal for C min , except for 2%-biochar treatment at 35°C. The findings highlight the necessity to consider the combined effects of soil moisture, temperature and the amount of biochar added for assessing C min in biochar-amended saline soils.

“…The resulting product can act as a soil conditioner that may increase soil fertility and structure, porosity, organic matter levels, water holding capacity, cation exchange capacity, as well as contribute to the suppression of plant pathogens (8)(9)(10). In addition to these benefits, compost products can replace the use of non-renewable organic products (11) and also composts can be used for the suppression of diseases caused by soil-borne plant pathogens (12).…”

Background: Composting process is a feasible biological treatment for the recycling of municipal solid wastes as a soil amendment. The principal requirement of compost for it to be safely used in soil is a high degree of stability or maturity, which implies stable organic matter content as well as the absence of phytotoxic compounds and plant or animal pathogens. Objectives: At the present study, the maturity and stability of composted municipal solid wastes at a biocompost plant was evaluated. Materials and Methods: For the assessment of compost maturity, important parameters including temperature, moisture content, pH, electrical conductivity, carbon-to-nitrogen (C/N) ratio, microbial parameters including Salmonella, total and fecal coliforms were measured during the composting process (80 days). In addition, phytotoxicity as seed germination index and heavy metals concentration (Zn, Cu, Cr, Ni, Cd and Pb) was determined at the end of the composting time. Results:The results showed that the C/N ratio decreased during the composting process (reached to 15.6) due to the loss of carbon and the increase in nitrogen content per unit material; also, the NH 4 + /NO 3 ratio decreased with increase in the time of composting and reached
