Abstract

Crop residue management has gained attention for its potential to increase soil organic matter and improve soil health in agricultural systems. For these purposes, pyrolysis of crop residues, to produce biochar, and its impacts on soils have been extensively studied, but torrefied biomass (biotorr), produced by torrefaction between 200 and 300 °C represents a promising alternative. Torrefaction offers advantages such as higher mass yields and lower production costs, which could make it an accessible and cost-effective soil conditioner.

This review synthesises current knowledge on the effects of torrefaction on the properties of biotorr and assesses its potential as a soil conditioner. The results showed that torrefaction affects the composition of biotorr differently depending on the feedstock and the torrefaction parameters. While the yield of biotorr decreased with increasing torrefaction temperature, it was still higher than that of biochar. Compared to the feedstock, the carbon content and stability of biotorr improved significantly. Our analysis also indicated higher levels of P and K in biotorr, although further research is needed to determine their bioavailability.

Given these results, biotorr shows a strong potential as a soil conditioner to improve soil health and support sustainable agriculture. However, it is now necessary to further investigate the potential of biotorr for agricultural application through field experiments, especially to assess how biotorr affects soil nutrient dynamics and carbon sequestration.

碳化生物质（Biotorr）在农业应用方面的潜力。回顾

作物残茬管理因其增加土壤有机质和改善农业系统土壤健康的潜力而受到关注。为了达到这些目的，人们已经广泛研究了农作物秸秆热解生产生物炭及其对土壤的影响，但在200至300°C之间热解生产的碳化生物质（biotorr）是一个很有前途的选择。烘烤具有较高的产量和较低的生产成本等优点，这可能使其成为一种易于使用且具有成本效益的土壤改良剂。这篇综述综合了目前关于温度对生物torr特性影响的知识，并评估了其作为土壤调节剂的潜力。结果表明，不同的原料和焙烧参数对生物torr的组成有不同的影响。随着温度的升高，生物炭的产率降低，但仍高于生物炭。与原料相比，生物torr的含碳量和稳定性显著提高。我们的分析还表明，生物torr中P和K的含量较高，尽管需要进一步研究以确定它们的生物利用度。鉴于这些结果，生物torr显示出作为土壤调理剂改善土壤健康和支持可持续农业的强大潜力。然而，现在有必要通过田间试验进一步研究生物torr在农业上的应用潜力，特别是评估生物torr如何影响土壤养分动态和碳固存。
