特点
Characteristic
再生农业是一种趋向于闭合养分循环的农业模式,它使生物群落的多样性更大,最大程度依赖于内部资源而不是外部资源投入
Regenerative organic agriculture is marked by tendencies towards closed nutrient loops, greater diversity in the biological community, fewer annuals and more perennials, and greater reliance on internal rather than external resources
[5]
原则
Principle
最小土壤扰动、最大化生物多样性、保持土壤覆盖、保持全年活根和引入牲畜
Minimize soil disturbance; maximize crop diversity; keep the soil covered; maintain living root year-round; integrate livestock
[6,14-15]
措施
Practice
免耕少耕(或在耕作后积极重建土壤群落);覆盖作物;培育田地的植物多样性(如多种作物轮作);整合畜牧业和种植业(如整体放牧)
(1) Abandoning/reducing tillage (or actively rebuilding soil communities following a tillage event); (2) Eliminating spatio-temporal events of bare soil by cover crop, etc; (3) Fostering plant diversity on the farm by crop rotation, etc; (4) Integrating livestock and cropping operations on the land such as holistic grazing
[15]
功能
Function
促进土壤肥力与健康;提高水的渗滤和减少地表径流,净化水源;增加生物多样性,增强生态系统的健康和复原能力;将当前农业的碳排放转化为显著的碳封存
(1) Contribute to generating/building soils and soil fertility and health; (2) Increase water percolation, water retention, and clean and safe water runoff; (3) Increase biodiversity and ecosystem health and resiliency; (4) Invert the carbon emissions of our current agriculture to one of remarkably significant carbon sequestration thereby cleansing the atmosphere of legacy levels of CO2
