“…Our outcomes on chemical characterization of the substrates are in line with those from Tian et al (2012) who reported lower pH values in a [1] For growing substrates: see Table 1. [2] K, Ca, Mg, Zn and Na content expressed in mg/g. [3] Fe, Cu and Mn content expressed in µg/g.…”

“…Changes in soil porosity and size aggregate distribution following biochar applications promote soil structure modifications, leading also to ameliorations of many other chemical-physical properties such as electrical conductivity (EC), CEC, pH, and water holding capacity (De Pasquale et al, 2012;Ouyang et al, 2013) that have a fundamental role in the standardization of substrate for greenhouse crops. Up to now several researches on biochar agricultural use have been focused on its application on soil, few studies were conducted in containers (Altland & Locke, 2013;Vaughn et al, 2013;Street et al, 2014;Zaccheo et al, 2014), even less regarded its utilization as growing substrate for ornamental potted plants (Tian et al, 2012;Zhang et al, 2014).…”

Biochar from conifers wood was used in soilless culture as growing substrate alternative to peat for ornamental crops. Potted plants of Euphorbia × lomi Rauh cv. ‘Ilaria’ were grown with different mixtures (v:v) of brown peat and biochar in order to evaluate main physical and chemical characteristics of this biomaterial as well as its effect on plant growth, ornamental characteristics and nutrients uptake. Biochar addition to peat increased pH, EC and K content of the growing substrates, as well as air content and bulk density. Biochar content of substrates significantly affected plant growth and biomass partitioning: higher number of shoots and leaves, leaf area and leaf dry weight were recorded in plants grown in 40% peat-60% biochar, with respect to plants grown in 100% peat and secondarily in 100% biochar. Leaf chlorophyll content was higher in plants grown in 60% and 80% biochar, while biomass water use efficiency was higher with 60% biochar. Plant uptake of K and Ca increased as biochar content of the substrates increased. Hence, a growing substrate containing 40% brown peat and 60% conifers wood biochar was identified as the more suitable mixture allowing to have a high-quality production of Euphorbia × lomi potted plants.

“…There was no difference in the number of green leaves among plants grown in 0 to 80% biochar, and only 100% biochar reduced the number of green leaves significantly (data not shown). Similar to this result, Tian et al [38] reported that Calathea makoyana grown in 100% biochar had a lower leaf biomass, lower leaf number, and smaller leaf surface area than those grown in 0% biochar.…”

“…Similar to this result, Graber et al [23] reported that a small amount of biochar (1-5% by weight) could increase tomato and pepper growth in soilless medium. Tian et al [38] reported calathea (Calathea rotundifola cv. Fasciata) plants grown in 50% biochar had a higher total dry weight, yet those grown in 100% biochar had the lowest dry weights of three biochar percentages (0%, 50%, or 100% biochar by volume).…”

Poinsettia Growth and Development Response to Container Root Substrate with Biochar

et al. 2018

A greenhouse study was conducted to evaluate the growth and development of poinsettia 'Prestige Red' (Euphorbia pulcherrima) grown in a commercial peat-based potting mix (Sunshine Mix #1) amended with biochar at 0%, 20%, 40%, 60%, 80%, or 100% (by volume) at four different fertigation regimes: F1: 100 to 200 mg·L −1 nitrogen (N), F2: 200 to 300 mg·L −1 N (control), F3: 300 to 400 mg·L −1 N, or F4: 400 to 500 mg·L −1 N. The experiment was a two-factor factorial design with 10 replications for each combination of biochar by fertigation. As the percentage of biochar increased, root substrate pore space and bulk density increased, while container capacity decreased. Root rot and red bract necrosis only occurred in F4 combined with 100% biochar. Plants grown in 40% biochar had a similar growth and development to those in 0% biochar. Up to 80% biochar, plants exhibited no significant change, except in terms of dry weight, which decreased at higher biochar percentages (60% and 80%). In summary, at a fertigation rate of 100 mg·L −1 N to 400 mg·L −1 N, up to 80% biochar could be used as an amendment to peat-based root substrate with acceptable growth reduction and no changes in quality.

“…There is global interest in reducing, or eliminating, the use of peat in the horticultural industry and in finding environmentally and economically sustainable growth media. Biochar has been shown to be a useful replacement for peat (Tian et al 2012) and vermiculite (Headlee et al 2014), in terms of key nutrient availability and total biomass productivity.…”

Opportunities and constraints for biochar technology in Australian agriculture: looking beyond carbon sequestration

et al. 2014

View full text Add to dashboard Cite

Abstract. The application of biochar technology for soil amendment is largely based on evidence about soil fertility and crop productivity gains made in the Amazonian Black Earth (terra preta). However, the uncertainty of production gains at realistic application rates of biochars and lack of knowledge about other benefits and other concerns may have resulted in poor uptake of biochar technology in Australia so far. In this review, we identify important opportunities as well as challenges in the adoption of biochar technology for broadacre farming and other sectors in Australia. The paper highlights that for biochar technology to be cost-effective and successful, we need to look beyond carbon sequestration and explore other opportunities to value-add to biochar. Therefore, some emerging and novel applications of biochar are identified. We also suggest some priority research areas that need immediate attention in order to realise the full potential of biochar technology in agriculture and other sectors in Australia.
