Abstract Biochar and organic fertilizer are widely supported to maintain crop production sustainable development of agroecosystems. However, it is unclear how biochar alone or in combination regulate soil functional microbiomes their relationships ecosystem multifunctionality (EMF). Herein, a long-term (started 2013) field experiment, containing five fertilization treatments, was employed explore the effects applications on EMF (based 18 indicators productivity, nutrient supply, element cycling, microbial biomass) bulk rhizosphere [normalizing abundances 64 genes related carbon (C), nitrogen (N), phosphorus (P), sulphur (S) cycles]. Compared with single-chemical fertilization, inputs significantly enhanced most ecosystem-single functions and, particular, increased by 18.7–30.1%; taxa C-N-P-S cycles varying degree. The combined application showed better improvement these compared using them individually. Most populations soil, especially involved C degradation, nitrification, nitrate-reduction, P mineralization, S cycling positive associations at different threshold levels, which ultimately regulated pH availability. These results highlight strong links between agroecosystem functions, as well providing scientific support for inclusion agricultural services amendments. Graphical

Magnesium-doped biochars increase soil phosphorus availability by regulating phosphorus retention, microbial solubilization and mineralization

Biochar, Journal Year: 2024, Volume and Issue: 6(1)

Published: July 18, 2024

Abstract Despite fertilization efforts, phosphorus (P) availability in soils remains a major constraint to global plant productivity. Soil incorporation of biochar could promote soil P but its effects remain uncertain. To attain further improvements with biochar, we developed, characterized, and evaluated magnesium-oxide (MgO) sepiolite (Mg 4 Si 6 O 15 (OH) 2 ·6H O)-functionalized biochars optimized retention/release capacity. Field-based application these for improving their mechanisms during three growth stages maize was investigated. We leveraged next-generation sequencing unravel impacts on the growth-stage shifts functional genes regulating availability. Results showed insignificant variation between single super phosphate (F) combination raw (BF). However, occurrence Mg-bound minerals biochars’ surface adjusted charges properties improved retention slow release inorganic P. Compared BF, available (AP) 26.5% 19.1% higher 12-leaf stage blister stage, respectively, under MgO-optimized + F treatment (MgOBF), 15.5% sepiolite-biochar (SBF) physiological maturity. Cumulatively, AP 15.6% 13.2% MgOBF SBF relative BF. Hence, biomass, grain yield, uptake were highest SBF, respectively at harvest. Optimized-biochar amendment stimulated microbial 16SrRNA gene diversity suppressed expression starvation response transport-related while stimulating solubilization mineralization genes. Thus, promoted via combined processes slow-release retained phosphates, inducing organic P, respectively. Our study advances strategies reducing cropland limitation reveals potential field scale.

Enhancing phosphorus availability and dynamics in acidic soils through Rice straw biochar application: a sustainable alternative to chemical fertilizers

Frontiers in Sustainable Food Systems, Journal Year: 2025, Volume and Issue: 9

Published: Feb. 4, 2025

Phosphorus is a vital nutrient for crop growth, but its bioavailability often limited in acidic soils, which are prevalent many agricultural regions, including South China. These soils characterized by low phosphorus availability and high levels of fixation, exacerbate the need sustainable practices. Over-reliance on phosphate fertilizers has led to environmental concerns, such as accumulation eutrophication. This study investigates potential straw biochar improve dynamics two typical Chinese soils: high-phosphorus paddy soil low-phosphorus lateritic red soil. Using range application rates, we examined effects fractions, phosphatase activity, microbial biomass phosphorus. The results indicate that significantly increased availability, enhanced enzyme boosted content, especially phosphorus-deficient findings underscore solution enhancing management, improving fertility, reducing risks China similar regions. research contributes valuable insights into biochar’s practical applications agriculture, offering promising approach use efficiency health.
