“…Hammer et al (2014) reported that biochar favors mycorrhizal associations and therefore the increase in P absorption. Lehmann et al (2003) also observed an increase in P accumulation in the aerial part of caupi bean after biochar addition to the soil.…”

The production of biochar from organic residues promises to be an interesting strategy for the management of organic waste. To assess the effect of biochar on soil properties and the production and nutrition of common bean (Phaseolus vulgaris L.), three simultaneous experiments were conducted in a greenhouse with different biochar from organic residues (rice husk, sawdust, and sorghum silage) used as filtration material for swine biofertilizer. In ), arranged in a completely randomized design, with four repetitions. In the experiments, the use of biochar increased soil pH, cation exchange capacity, nutrient availability in the soil, and nutrient accumulation in grains. The biochar concentrations corresponding to the maximum production of grain dry matter of bean plants were 100, 68, and 71 L m −3 for biochar from rice husk filter (BRHF), biochar from sawdust filter (BSF), and biochar from sorghum silage filter (BSSF), respectively.

“…production. There were increasing evidences suggested that biochar application could help combat salinity stress to plant and improve productivity in saline croplands (Drake et al, 2015;Lashari et al, 2015;Hammer et al, 2014). Akhtar et al (2015) have reported that incorporation of biochar into salt-affected soil could alleviate salinity stress mainly because of its high salt adsorption potential, decreasing osmotic stress by enhancing soil moisture content, and releasing mineral nutrients.…”

• 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.

“…Recently, it has been shown using P isotopes that mycorrhizae can actively mine biochar pores for (loaded) phosphorus (Hammer et al 2014). Other trials have focused on selecting the most efficient strains of microorganisms to utilize nutrients contained in biochar (Postma et al 2010).…”

“…The effect of biochar on root development, e.g. root surface, has also rarely been described, despite its importance regarding pollutant uptake (Hammer et al 2014;Graber et al 2015;Rees et al 2016). All these plant-related research topics should be targeted in the near future to improve understanding of biochar's effect in vegetated soils (Kammann, Graber 2015).…”

Key priorities in biochar research for future guidance of sustainable policy development have been identified by expert assessment within the COST Action TD1107. The current level of scientific understanding (LOSU) regarding the consequences of biochar application to soil were explored. Five broad thematic areas of biochar research were addressed: soil biodiversity and ecotoxicology, soil organic matter and greenhouse gas (GHG) emissions, soil physical properties, nutrient cycles and crop production, and soil remediation. The highest future research priorities regarding biochar’s effects in soils were: functional redundancy within soil microbial communities, bioavailability of biochar’s contaminants to soil biota, soil organic matter stability, GHG emissions, soil formation, soil hydrology, nutrient cycling due to microbial priming as well as altered rhizosphere ecology, and soil ph buffering capacity. Methodological and other constraints to achieve the required LOSU are discussed and options for efficient progress of biochar research and sustainable application to soil are presented.
