A Review of Biochar and Soil Nitrogen Dynamics
Interest in biochar stems from its potential agronomic benefits and carbon sequestration ability. Biochar application alters soil nitrogen (N) dynamics. This review establishes emerging trends and gaps in biochar-N research. Biochar adsorption of NO3, up to 0.6 mg g biochar, occurs at pyrolysis temperatures >600 °C with amounts adsorbed dependent on feedstock and NO3 concentration. Biochar NH4 ...
متن کاملBiochar effects on soil biota e A review
Soil amendment with biochar is evaluated globally as a means to improve soil fertility and to mitigate climate change. However, the effects of biochar on soil biota have received much less attention than its effects on soil chemical properties. A review of the literature reveals a significant number of early studies on biochar-type materials as soil amendments either for managing pathogens, as ...
متن کاملDecreased Soil Nitrification Rate with Addition of Biochar to the Acid Soils
This study aimed to investigate the effects of mixed biochar on the nitrification rate in acidic soils. A 15N tracer experiment with (15NH4)2SO4 was conducted to determine the nitrification rates of four acidic agricultural soils with pH 4.03–6.02 in Yunnan Province, Southern China. The accumulation of 15N-NO3− and nitrification rates decreased with the addition of biochar at the end of incubat...
متن کاملBiochar-rhizosphere interactions - A review.
Biochar is a solid material of biological origin obtained from the biomass carbonization, designed as a mean to reduce greenhouse gases emission and carbon sequestration in soils for a long time. Biochar has a wide spectrum of practical utilization and is applied as a promising soil improver or fertilizer in agriculture, or as a medium for soil or water remediation. Preparations of biochar incr...
متن کاملBiochar as a sorbent for contaminant management in soil and water: a review.
Biochar is a stable carbon-rich by-product synthesized through pyrolysis/carbonization of plant- and animal-based biomass. An increasing interest in the beneficial application of biochar has opened up multidisciplinary areas for science and engineering. The potential biochar applications include carbon sequestration, soil fertility improvement, pollution remediation, and agricultural by-product...
