Evaluation of the potential for nine established and emerging interventions to reduce soil carbon losses and increase stocks in grazing systems: A case study for Aotearoa New Zealand

Summary

Abstract This article reviews nine soil carbon interventions to reduce soil carbon losses or increase stocks in grazing management systems, using their potential application in Aotearoa New Zealand (A‐NZ) as a case study. The interventions are classified into three strategies: (1) increasing carbon inputs through deep‐rooting and diverse species grasslands, reducing forage cropping and deferred grazing management; (2) increasing protection of carbon stocks by water table management on organic soils, reducing cropping on organic soils, full inversion tillage grassland renewal, the addition of clay minerals and enhanced rock weathering and (3) the adoption of integrated systems including establishing tree clusters into grasslands and agroforestry. We estimated the land area where these inter
