In Maragua, Murang\u2019a County, researchers are testing whether combining crushed basalt, biochar, and compost can help restore soil fertility, improve crop productivity, and remove carbon dioxide from the atmosphere. The CarboRestore field experiment brings together IITA<\/u><\/a>, le University of Antwerp<\/u><\/a>, and Tukalime Ventures to investigate an approach that links soil restoration with climate change mitigation and sustainable agriculture. Led by John Choptiany from IITA\u2019s CGIAR Climate Action program, the project is investigating how degraded soils can be restored to support productive agriculture while storing carbon.<\/p>\n\n\n\n

Building a new soil layer<\/h3>\n\n\n\n

After nearly two years of planning, the experiment moved into field implementation. The approach combines three techniques: enhanced rock weathering, biochar application, and soil carbon sequestration through organic matter. Together, these are intended to improve soil properties while increasing carbon storage. <\/p>\n\n\n\n
