Abstract

Abstract. Quantifying the impact of biochar on carbon persistence across soil textures is complex, owing to the variability in soil conditions. Using artificial soils with precise textural and mineral compositions, we can disentangle the effects of biochar from the effects of soil particle size. We can show that biochar application significantly reduces the early-stage carbon mineralization rates of plant residues in various soil textures (from 5 % to 41 % clay) but more significantly in sandy soils. Clay and silt particles alone also reduce C mineralization, but the magnitude of the changes is negligible compared to the impact of biochar. This finding suggests that biochar can compensate for the lack of clay in promoting C persistence in soil systems. This short report contributes substantially to understanding soil texture and biochar application interactions.
生物炭在粗质土壤中比在细质土壤中更能降低植物残留物的早期矿化率——一种人工土壤方法
摘要。由于土壤条件的可变性,量化生物炭对土壤结构中碳持久性的影响是复杂的。使用具有精确质地和矿物成分的人工土壤,我们可以将生物炭的影响与土壤颗粒大小的影响分开。我们可以发现,生物炭的施用显著降低了各种土壤质地(从5%到41%的粘土)中植物残留物的早期碳矿化率,但在沙质土壤中更为显著。粘土和淤泥颗粒本身也会降低碳矿化,但与生物炭的影响相比,这种变化的幅度可以忽略不计。这一发现表明,生物炭可以弥补粘土的缺乏,促进土壤系统中碳的持久性。这篇简短的报告对理解土壤质地和生物炭施用的相互作用有重要的贡献。

期刊介绍: SOIL is an international scientific journal dedicated to the publication and discussion of high-quality research in the field of soil system sciences. SOIL is at the interface between the atmosphere, lithosphere, hydrosphere, and biosphere. SOIL publishes scientific research that contributes to understanding the soil system and its interaction with humans and the entire Earth system. The scope of the journal includes all topics that fall within the study of soil science as a discipline, with an emphasis on studies that integrate soil science with other sciences (hydrology, agronomy, socio-economics, health sciences, atmospheric sciences, etc.).
