Beneficial Effects of Biochar Application with Nitrogen Fertilizer on Soil Nitrogen Retention, Absorption and Utilization in Maize Production

Agronomy, Journal Year: 2022, Volume and Issue: 13(1), P. 113 - 113

Published: Dec. 29, 2022

The irrational use of nitrogen (N) fertilizer has become a major threat to soil quality and food security, resulting in serious ecological environmental problems. Holistic approaches N application are required maintain high utilization efficiency (NUE) sustainable agriculture development. Biochar is an efficient carbon-rich material for amending promoting crop uptake, but knowledge pertaining the effects biochar on fertilizers still limited. In this study, field plot experiment was designed detect combined (0, 15 30 t ha−1) (204, 240 276 kg nutrient levels, NUE, plant growth performance production maize. results demonstrated that can significantly decrease pH increase contents organic carbon, mineral N, available phosphorus potassium. uptake content were largely promoted by addition biochar, higher leaf photosynthetic efficiency, dry matter accumulation grain yields. highest yields (14,928 achieved using ha−1 combination with NUE value (46.3%) reached 204 blended biochar. According structural equation modeling, beneficial biomass maize attributed direct related chemical properties parameters. conclusion, effective strategy enhance increasing fertility, improving growth.

Impact of biochar amendment on soil microbial biomass carbon enhancement under field experiments: a meta-analysis

Biochar, Journal Year: 2025, Volume and Issue: 7(1)

Published: Jan. 2, 2025

Abstract Biochar is well-accepted as a viable climate mitigation strategy to promote agricultural and environmental benefits such soil carbon sequestration crop productivity while reducing greenhouse gas emissions. However, its effects on microbial biomass (SMBC) in field experiments have not yet been thoroughly explored. In this study, we collected 539 paired globally published observations study the impacts of biochar SMBC under experiments. Our results suggested an overall positive impact (21.31%) SMBC, varying widely with different conditions, types, properties, management practices. application exhibits significant climates mean annual temperature (MAT) < 15 °C precipitation (MAP) between 500 1000 mm. Soils coarse fine texture, alkaline pH (SPH), total organic (STC) content up 10 g/kg, nitrogen (STN) 1.5 low cation exchange capacity (SCEC) 5 cmol/kg received higher SMBC. produced from residue, specifically cotton maize at pyrolysis (BTM) 400 °C, (BPH) 8 9, rate (BAP) t/ha, high ash (BASH) > g/kg resulted increase Low (BTC) (BTN) positively affect Repeated significantly increased by 50.11%, fresh (≤ 6 months) enhanced compared single aged biochar. applied fertilizer (up 300 kg/ha) manure/compost showed improvements but co-application straw slight negative The best-fit gradient boosting machines model, which had lowest root square error, demonstrated relative importance various factors effectiveness: biochar, soil, climate, applications 46.2%, 38.1%, 8.3%, 7.4%, respectively. Soil clay proportion, BAP, application, MAT were most critical variables for that efficiency varies climatic environments, practices, feedstock types. meta-analysis provides first quantitative review demonstrating potential rehabilitating nutrient-deprived soils promoting sustainable land management.

Abstract Biochar incorporation into soil has shown potential, in enhancing nitrogen fertilizer (N-fertilizer) efficacy and organic carbon content (SOC). This study addresses a critical gap the literature by investigating effects of biochar addition over seven-year period (2014–2020) on inorganic N, SOC, pH Haplic Luvisol. The research involved rain-fed field experiment, with crop rotation comprising spring barley, maize, wheat, pea. Biochar, applied at rates 0, 10, 20 t ha −1 2014, was reapplied to specific plots 2018. also combined N-fertilizer three level (N0, N1, N2). Results showed significant interactive influence combination NO 3 − NH 4 + contents. Intriguingly, 10 consistently decreased N levels across most examined months. Increasing application led rise pH, establishing clear, negative correlation between content. significantly increased SOC compared control, particularly after reapplication However, this effect diminishing trend time. suggests that incorporating treatments may enhance effectiveness. long-term implications mineralization are individual combinations.
