Biochar from crop residues

Global raster files (5 arc-minutes resolution) for biochar production from residues. See ReadMe.txt for details and metadata. Files are provided for a) crop-residue resource from 42 crops worldwide; b) the potential for biochar production from these residues; and c) how much of this biochar carbon would remain sequestered after 100 year's decomposition. The biomass resource assessment includes amounts that can be sustainably harvested, and also how much is available after allowing for competing use in livestock systems.本数据集为针对利用残余物生产生物炭（biochar）的全球栅格数据集，分辨率为5弧分。详细信息与元数据请参阅ReadMe.txt文件。本次提供的文件包含以下三类： a) 全球范围内42种农作物的农作物残余物资源量； b) 基于上述残余物可实现的生物炭生产潜力； c) 该生物炭所含碳经100年分解后仍将被固存的碳量。 本次生物量资源评估涵盖了可可持续采收的资源量，以及扣除畜牧系统竞争性用途后可获取的残余物资源量。
