Crop-livestock reintegration could reduce the environmental footprint of decoupled crop and livestock production related to biogeochemical cycles. Previous experiments showed that replacing fallow periods in annual crop rotations with grazed cover crops increases total nitrogen (N) and organic carbon (SOC), based on topsoil sampling and stocks compared by equivalent soil depth. Stock comparisons based on topsoil sampling or equivalent soil depth, rather than whole-profile sampling or equivalent soil mass, can erroneously report stock gains that have not occurred. Evidence of crop-livestock integration effects on commercial farms is needed.

在智利地中海气候火山土壤中，与纯农作物农场相比，综合农作物农场的表层土壤氮和碳含量更高


作物-畜牧业的再整合可以减少与生物地球化学循环相关的作物和畜牧生产脱钩对环境的影响。以前的实验表明，根据表层土壤采样和同等土壤深度的库存比较，用放牧覆盖作物取代年度作物轮作的休耕期会增加总氮 （N） 和有机碳 （SOC）。基于表层土壤采样或等效土壤深度的存量比较，而不是基于全剖面采样或等效土壤质量的存量比较，可能会错误地报告尚未发生的存量增加。需要证明作物-畜牧业整合对商业农场的影响。
