Spokas -2010 - Review of the stability of biochar in soils: predictability of O:C molar ratios

This variability is based on the conditions of pyrolysis and the > > > biomass parent material, with biochar spanning the range of various forms of black carbon. Thereby, this > > > variability induces a broad spectrum in the observed rates of reactivity and, correspondingly, the overall > > > chemical and microbial stability. From evaluating the current biochar and black carbon degradation studies, > > > there is the suggestion of an overall relationship in biochar stability as a function of the molar ratio of oxygen to carbon (O:C) in the resulting black carbon. In general, a molar ratio of O:C lower than 0.2 appears to > > > provide, at minimum, a 1000-year biochar half-life. The O:C ratio is a function of production temperature, > > > but also accounts for other impacts (e.g., parent material and post-production conditioning/oxidation) that are not captured solely with production temperature. Therefore, the O:C ratio could provide a more robust indicator of biochar stability than production parameters (e.g., pyrolysis temperature and biomass type) or volatile matter determinations.

Book List thread
Hey there all. Wanted to start a book thread to help build out the utility of the Permaculture community here and make any transitions like the one we're making easier on other folks in advance of 6/30. Please share your book lists as well!

Permaculture in Poland's Driest Region, Part 1: The Valley of Mists, Łukasz Nowacki - Earth Day 2022
piped.kavin.rocks PipedAn alternative privacy-friendly YouTube frontend which is efficient by design.
In this vlog American filmmaker Jonathan Ramsey meets Łukasz Nowacki, one of Poland's growing number of permaculture farmers. Located on the outskirts of the tiny village of Gapinin in Poland's Łódź region, Łukasz's farm - named The Valley of Mists - is in an area with very damaged soils and huge problems with drought, making it one of the most difficult places in Poland to do permaculture. Using compost and a variety of smart agroforestry methods since 2013, Łukasz is transforming this sandy, barren soil into an oasis of resilience and regeneration.

Landwirtschaft im Einklang mit der Natur Die moderne Landwirtschaft betreibt einen Raubbau an der Natur, weil sie die Böden langfristig ihrer Nährstoffe beraubt, durch Überdüngung aus der Balance bringt, den Bodenschichten der Erosion preisgibt und am Ende versalzt. Bleibt es bei den aktuellen Metho...
