A critical review of biochar-based nitrogen fertilizers and their effects on crop production and the environment

Biochar, Journal Year: 2022, Volume and Issue: 4(1)

Published: June 13, 2022

Abstract Globally, nitrogen (N) fertilizer demand is expected to reach 112 million tonnes support food production for about 8 billion people. However, more than half of the N lost environment with impacts on air, water and soil quality, biodiversity. Importantly, loss contributes greenhouse gas emissions climate change. Nevertheless, where application limited, severe depletion fertility has become a major constraint sustainable agriculture. To address issues low use efficiency (NUE), biochar-based fertilizers (BBNFs) have been developed reduce off-site maximize crop uptake. These products are generally made through physical mixing biochar or via coating chemical such as prilled urea biochar. This review aims describe manufacturing processes BBNFs, critically assess effects properties, yield pathways. Graphical

Biochar as a Soil Amendment for Restraining Greenhouse Gases Emission and Improving Soil Carbon Sink: Current Situation and Ways Forward

Sustainability, Journal Year: 2023, Volume and Issue: 15(2), P. 1206 - 1206

Published: Jan. 9, 2023

The global exponential rise in greenhouse gas (GHG) emissions over the last few decades has triggered an urgent need to contextualize low-cost and evergreen technologies for restraining GHG production enhancing soil carbon sink. GHGs can be mitigated via incorporating biochar into matrix sequestrate mineralized a stable form upon organic matter decomposition soil. However, efficiency of using offset from terrestrial ecosystems is still debatable. Moreover, literature, shows high functionality short-term laboratory studies, but it minimal or negative impacts field-scale experiments, leading conflicting results. This paper synthesizes information on ability mitigate dioxide (CO2), nitrous oxide (N2O), methane (CH4) biomass, with emphasis cropland soils. feedstock type, pyrolysis temperature, application rate factors showed significant effects controlling effectiveness emissions. Our study demonstrates that biochar, taken as whole, seen powerful easy-to-use tool halting rising tide Nonetheless, future research should focus (i) identifying other indirect related physicochemical characters (such pH/EH CaCO3 contents) may control (ii) fabricating aged biochars low nitrogen footprints, (iii) functionalizing biologically activated suppress CO2, CH4, N2O Overall, our paradoxical findings highlight functionalize modern capacity abate locking up their release carbonaceous lattice biochar.

Biochar co-pyrolyzed from peanut shells and maize straw improved soil biochemical properties, rice yield, and reduced cadmium mobilization and accumulation by rice: Biogeochemical investigations

Journal of Hazardous Materials, Journal Year: 2024, Volume and Issue: 466, P. 133486 - 133486

Biochar is an eco-friendly amendment for the remediation of soils contaminated with cadmium (Cd). However, little attention has been paid to influence and underlying mechanisms co-pyrolyzed biochar on bioavailability uptake Cd in paddy soils. The current study explored effects from peanut shells (P) maize straw (M) at different mixing ratios (1:0, 1:1, 1:2, 1:3, 0:1, 2:1 3:1, w/w), bacterial community fractionation soil, its by rice plant. addition, particularly P1M3 (P/M 1:3), significantly elevated soil pH cation exchange capacity, transferred mobile residual fraction, reduced availability rhizosphere soil. application decreased concentration tissues (root, stem, leaf, grain) 30.0%- 49.4%, compared control. Also, enhanced microbial diversity indices relative abundance iron-oxidizing bacteria Moreover, was more effective promoting formation iron plaque, increasing sequestration plaque than other treatments. Consequently, highest yield lowest accumulation were observed following application. This revealed feasibility applying facilitating Cd.
