Comparing the influence of organic matter and fertiliser inputs on soil organic carbon and grain production

To identify on-farm management strategies to increase soil organic carbon (SOC) and quantify any associated risks and benefits in a grain production system.In this trial the Facey Group wanted to determine whether:Altering inputs to increase plant biomass would subsequently increase soil carbon andAmending soils with compost would increase soil carbon storage or provide agronomic benefits.本研究旨在识别可提升土壤有机碳（soil organic carbon, SOC）的农场生产管理策略，并量化谷物生产系统中相关的风险与收益。本次试验中，费西集团（Facey Group）旨在验证两项核心假设：其一，通过调整生产投入以提升植物生物量，是否可进而增加土壤碳含量；其二，向土壤施用堆肥是否可提升土壤碳储存能力，或带来农艺效益。
