主 题：Biochar Earthworm Earthworm biomarkers Soil health Soil fertility
摘 要：Numerous studies have unequivocally demonstrated that biochar and,to a lesser degree,earthworms can independently improve soil fertility and crop productivity,although information about their co-application effects on soil characteristics is *** this review,(1)earthworm biomarkers and underlying influencing factors,as well as the changes in the amended soil quality in response to co-application of earthworms and biochar are presented,(2)the functional interactions between earthworms and biochar in soil are summarized;(3)the principles governing the synergetic effects of biochar and earthworms on soil quality enhancement are probed;and(4)alternative strategies to optimize the efficacy of earthworm and biochar amendments are *** is noteworthy that while low doses of biochar can have a positive effect on various earthworm biomarkers,including growth and reproduction,restoration of the intestinal environment,and the mitigation of cellular organelle toxicity and genetic damage,high biochar dosages can yield adverse ***,earthworms play a crucial role in distributing biochar particles deeper into the soil matrix,bolstering carbon sequestration potential,and enhancing the persistence and efficiency of biochar ***,earthworms stimulate the production of soil extracellular enzymes by microorganisms,which are pivotal to the processing,stabilization,and decomposition of soil organic matter,as well as nutrient cycling in terrestrial ***,they enhance the binding affinities of these enzymes to ***,changes in earthworm biomarkers in response to biochar integration are predominately governed by biochar properties and dosage,contact time,and soil type.
