“…Subedi et al (2016a) observed up to a 50% increase in ryegrass yield in sub-acid silt-loam soil and a 44% increase in calcareous sandy soil. In an Australian calcareous soil amended with pine and poplar wood BCs, Marks et al (2014) reported negative effects on lettuce and ryegrass yields. The authors reported this as restricted nutrient availability for the crops limited by the increased VM content of BC that increased competition with the microorganisms plus phosphate precipitation to non-available forms due to biochar chemistry.…”

“…Others have reported no yield effect (Cornelissen et al, 2013;Uzoma et al, 2011;Nelissen et al, 2015;Subedi et al, 2016aSubedi et al, , 2016bNielsen et al, 2014;Tammeorg et al, 2014;Suddick and Six, 2013;Schmidt et al, 2014;Bass et al, 2016). Conversly, few studies have instead described reduced crop yields (Deenik et al, 2010;Baronti et al, 2010;Marks et al, 2014;Nelissen et al, 2014;Bass et al, 2016;Butnan et al, 2015;Laghari et al, 2015). Therefore, interest has emerged to study BC effects that negatively alter crop growth (Jeffery et al, 2011(Jeffery et al, , 2015aSpokas et al, 2012;Biederman and Harpole, 2013;Wang et al, 2016, Olmo et al, 2016.…”

“…Negative effects on crop growth are mostly reported with BCs obtained from municipal waste, food waste, and sewage sludge because their excessive Na contents increase soil salinity (Liu et al, 2013;Wisnubroto et al, 2011;Rajkovich et al, 2012). Other negative effects from plant-and wood-based BCs are due to one of the following causes: high application rates, high volatile matter contents detrimental to crop growth, reduced plant available N, or negative liming effect in alkaline and calcareous (Deenik et al, 2010;Nelissen et al, 2014;Laghari et al, 2015;Bass et al, 2016;Marks et al, 2014). Baronti et al (2010), in a pot experiment with high BC rates, reported a perennial ryegrass yield increase by 29−120% after BC derived from orchard pruning was applied at between 30-60 t ha −1 to sandy-loam soil with sub-acid pH.…”

Crop response to soils amended with biochar: expected benefits and unintended risks

et al. 2017

Biochar (BC) from biomass waste pyrolysis has been widely studied due to its ability to increase carbon sequestration, reduce greenhouse gas emissions, and enhance both crop growth and soil quality. This review summarises the current knowledge of BC production, characterisation, and types, with a focus on its positive effects on crop yield and soil properties vs the unintended risks associated with these effects. Biochar-amended soils enhance crop growth and yield via several mechanisms: expanded plant nutrient and water availability through increased use efficiencies, improved soil quality, and suppression of soil and plant diseases. Yield response to BC has been shown to be more evident in acidic and sandy soils than in alkaline and fine-textured soils. Biochar composition and properties vary considerably with feedstock and pyrolysis conditions so much that its concentrations of toxic compounds and heavy metals can negatively impact crop and soil health. Consequently, more small-scale and greenhouse-sited studies are in process to investigate the role of BC/soil/crop types on crop growth, and the mechanisms by which they influence crop yield. Similarly, a need exists for long-term, field-scale studies on the effects (beneficial and harmful) of BC amendment on soil health and crop yields, so that production guidelines and quality standards may be developed for BCs derived from a range of feedstocks.

“…However, Zhang et al [20] found that although biochar could immobilize soil Cd, it did not improve plant growth. Moreover, Marks et al [21] documented that some biochars stimulated plant growth, whereas others showed strong inhibition. Prapagdee et al [22] also found that 10% biochar could promote plant growth, whereas 15% biochar treatment caused adverse effects.…”

Butachlor is an important chloroacetanilide herbicide applied in agriculture all over the world. In China, butachlor is now one of the three most widely utilized herbicides, with a yield of 1×10 4 t per year [1]. The application of butachlor in large quantities IES may cause the contamination of underground water, surfacewater, and paddy soil in China, leading to disruption of the environment and ecosystems [2]. At the same time, anthropogenic activities result in increasing pollution of heavy metals that cannot be degraded and hence accumulate in the environment. Heavy metals threaten soil quality, plant survival, and human health, and their mobility are of global concern [3]. Cadmium (Cd) is a non-essential metal element that may cause damage even at very low levels. Cd in croplands can result in enhanced dietary exposure through Pol. J. Environ. Stud. Vol. 26, No. 2 (2017), 619-625 AbstractWe investigated the effects of high-productivity plant hybrid giant Napier (HGN)-derived biochars prepared at different pyrolysis temperatures on Cd migration in a soil-cabbage system contaminated with Cd and butachlor. The results showed that with the enhancement amount of biochar applied, soil pH and electrical conductivity (EC) increased, whereas the available Cd content dropped significantly (P<0.05). The maximum decreasing value (66.08%) of the available Cd content was observed, while with 5% biochar prepared at 400ºC. Further application of this biochar caused a significant biomass increase and a Cd content decrease of cabbage (P<0.05). Notably, the cabbage biomass even increased to 573.58%. The application inhibited Cd migrations from the soil to the underground part and, successively, the overground part of the cabbage, leading to reduced bioaccumulation of Cd. With 5% biochar prepared at 400ºC, the maximum decrease of the Cd content reached up to 90% in the aboveground part and 70% in the underground part of cabbage, respectively. Hence, the investigation demonstrates that high-productivity HGN-derived biochar can be a good candidate for immobilizing Cd and reducing its bioaccumulation.

“…Biochar amendments increased soil phosphorus (P) availability and therefore enhanced crop productivity especially for low fertility soils (Blackwell et al, 2010;Biederman and Harpole, 2013;Marks et al, 2014;Subedi et al, 2016). When incorporation into soil, biochar can increase P availability through directly P release from biochar and indirectly improve P use efficiency by changes in soil pH, CEC, structure, decrease P leaching and affect soil P related microbial activity Jiang et al, 2015;Zhai et al, 2015;Christel et al, 2016).…”

• Lower pyrolysis temperature (b 400°C) biochar retained P availability and increased plant growth.• Negative (antagonistic) interaction occurred between biochar and P fertilization on the biomass production and plant P concentration • Very limited utility value of biochar application occurred in saline sodic soil. G R A P H I C A L A B S T R A C TThe growth of Suaeda salsa in biochar amended saline sodic soils with (P 1 ) or without (P 0 ) P fertilization.a b s t r a c t a r t i c l e i n f o Little is known about the interactive effects between biochar application and phosphorus (P) fertilization on plant growth and P uptake. For this purpose, five wheat straw biochars (produced at 25°C, 300°C, 400°C, 500°C and 600°C for 4 h) with equal P (36 mg kg −1 ) amount, with and without additional P fertilization (100 mg kg) were applied in a pot experiment to investigate the growth of Suaeda salsa and their uptake of P from biochar and P fertilization amended saline sodic soil. Soil P fractions, dry matter yield, and plant P concentrations were determined after harvesting 90 days. Our results confirmed that relatively lower pyrolysis temperature (b400°C) biochar retained P availability and increased plant growth. The plant P concentration was significantly correlated with NaHCO 3 -P i (P b 0.05), and NaOH-P i (P b 0.1) during early incubation time (4 days) for biochar amended soil. As revealed by statistical analysis, a significant (P b 0.05) negative (antagonistic) interaction occurred between biochar and P fertilization on the biomass production and plant P concentration. For plant biomass, the effects size of biochar (B), P, and their interaction followed the order of B × P (0.819) N B (0.569) ≈ P (0.568) based on the partial Eta squared values whereas the order changed as P (0.782) N B (0.562) N B × P (0.515) for plant P concentration. When biochar and P fertilization applied together, phosphate precipitation/sorption reaction occurred in saline sodic soil which explained the decreased plant P Contents lists available at ScienceDirectScience of the Total Environment j o u r n a l h o m e p a g e : w w w . e l s e v i e r . c o m / l o c a t e / s c i t o t e n v availability and plant yield in saline sodic soil.
