Persistence in soil of Miscanthus biochar in laboratory and field conditions

| Type artikkel: Publisert studie

Kategori: Biokull, Karbon og karbonlagring, Klima og miljø, Matjord

Evaluating biochars for their persistence in soil under field conditions is an important step towards their implementation for carbon sequestration. Current evaluations might be biased because the vast majority of studies are short-term laboratory incubations of biochars produced in laboratory-scale pyrolyzers.

Karbon i jord – kilder, handtering, omdanning

Innholdet av organisk materiale og dermed karbon i jord er viktig for egenskapene jorda har som dyrkingsmedium og for jordbrukets klimaregnskap. Karbon tilføres via plantenes fotosyntese og annen tilførsel av organisk materiale. Karbon fjernes med avlinger og nedbryting av organisk materiale i jorda. For å kunne utvikle jordbruksmetoder som bidrar til lagring av mest mulig karbon i jord er det viktig å forstå prosessene knytta til nedbryting, omdanning og oppbygging av organisk
materiale i jord.

Vermi – biochar as alternative to peat as growing substrate for greenhouse vegetables

Biochar is a novel soil amendment technique with a potential of sequestering atmospheric carbon into soil with an increase in certain soil quality parameters essential for crop production. Intense use of peat as growing media, especially in horticulture, has led to a huge exploitation of stable carbon from wetland mosses into the atmosphere accelerating climate change.

Prosjektets hovedmål er å undersøke hvilket potensiale biokull fra organisk avfall har til å sekvestere karbon og forbedre kvaliteten av utarmet, sandholdig og/eller sur jord i Zambia.

By converting organic matter into biochar, which has a high stability, carbon can remain fixed in soils for several centuries. Carbon sequestration via pyrolysis and deposition of biochar in soil has evolved over the last decade. Biochar is produced by heating organic material under oxygen-free conditions together with bio-oil and gas that can be used for energy purposes. A significant amount of research has recently contributed to an increased understanding of biochar effects on carbon sequestration, greenhouse gas emissions and agronomy.

However, more research is needed on biochar effects on plant and grain yields, the influence of production technologies on biochar quality and its effect on soil fertility, pyrolysis bio-oil quality and cost reductions. Implementation will further require a combination of substantial innovation, private and public investment, systems of incentives and integration in existing agricultural practices and governance systems.



The main objective of CAPTURE+ is to develop biochar systems as a tool for achieving a zero emission society by applying an interdisciplinary approach for development, assessment and implementation in agriculture and forestry.



This is achieved by improving technical, economical, political and social factors that currently limit biochar implementation in agriculture and forestry, using biotechnology and nanotechnology to improve the production process, developing scenarios for sustainable biochar systems, establishing a demonstrator platform, ensuring biochar quality, engaging stakeholders in implementation paths, and increasing awareness of its potential. The novelty lies in the integration of enabling nano- and biotechnologies to improve the process and ensure enhanced value of end products that may permit large scale adoption. The integration of economic, societal and political analysis, including stakeholder involvement in technology development and implementation is also novel.
