“…Most importantly, the interaction effects between biochar and P fertilizer need to be clarified in agricultural field (Tammeorg et al, 2014;Jain et al, 2016). Chan et al (2010) found a positive (synergistic) interaction between biochar and nitrogen fertilizer where they found biochar application significantly increased plant yield and N (nitrogen) use efficiency in the presence of N fertilization (Chan et al, 2008).…”

• 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. The negative interaction effects between biochar and P fertilization indicated limited utility value of biochar application in saline sodic soil.

“…The effect of biochar on soil hydrology depends on the feedstock and amount of biochar added, biochar quality including particle size distribution, pore size distribution, reactive surface area, and hydrophobic compounds on the biochar surface and soil type including soil water repellence, soil aggregation, soil bulk density, and soil texture. Soil water content in soil-biochar mixtures is not always enhanced with the effects being dependent on application rate and usually with more pronounced increases in the macroporosity than the microporosity of soils (Tammeorg et al 2014a(Tammeorg et al , 2014bJeffery et al 2015b;Masiello et al 2015). The suggested use of biochar as a component of horticultural growing media (Méndez et al 2015;Vaughn et al 2015;Kern et al, this issue) makes it necessary to differentiate between soils and growing media for calculating the influence of biochar on retention of plant-available water.…”

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.

“…In such environmental conditions, the use of biochar can enhance soil structure, nutrients and water holding capacity (Kammann et al 2011;Smider and Singh. 2014;Tammeorg et al 2014;Cao et al 2014;Stella Mary et al 2016). …”

“…Biochar has been reported as a soil amendment for enhancing soil structure, increasing crop yields Liu et al 2012;Tammeorg et al 2014), increasing microbial activity (Hossain et al 2010;Jiang et al 2016) and decreasing soil bulk density (Laird et al 2010). Due to its positive effect on the physical, chemical and biological properties of soils, biochar indirectly helps improving crop productivity (Liu et al 2013;Smider and Singh 2014;Kaudal et al 2016).…”
