This project focuses on investigating ERW with cocoa (Theobroma cacao L.) production in Brazil/Indonesia. Cocoa is typically grown on highly weathered nutrient-poor acidic soils (oxisols). These soils are infertile because of low pH, calcium (Ca), magnesium (Mg), and potassium (K) levels but high aluminium (Al) content. The warm climate conditions of Brazil/Indonesia soils are ideal for carbon dioxide removal by ERW and generating agricultural and soil co-benefits.Building on prior studies with cocoa grown on basalt-amended oxisols in Malaysia, this project has the central aim of rigorously evaluating ERW deployment on cocoa under field conditions over three growing seasons to quantify carbon removal, the response of cocoa tree growth and yields, and improvements in soil fertility.Extensive logistical and technical support will be available to the student in setting up, accessing, and running these field experiments from Mondelez International. Costs of basalt supply, transportation and distribution will be covered by Mondelez International, who will undertake operations for annually distributing the crushed material.

该项目重点调查巴西/印度尼西亚可可 (Theobroma cacao L.) 生产中的战争遗留爆炸物。可可通常生长在高度风化、营养贫乏的酸性土壤（氧化土）上。这些土壤由于 pH 值、钙 (Ca)、镁 (Mg) 和钾 (K) 含量低而铝 (Al) 含量高而贫瘠。巴西/印度尼西亚土壤温暖的气候条件非常适合通过战争遗留爆炸物去除二氧化碳，并产生农业和土壤协同效益。该项目以马来西亚玄武岩改良氧化土上种植的可可先前研究为基础，其中心目标是严格评估在三个生长季节的田间条件下对可可进行ERW部署，以量化碳去除、可可树生长和产量的反应以及土壤肥力的改善。将提供广泛的后勤和技术支持学生可以设置、访问和运行亿滋国际的这些现场实验。玄武岩供应、运输和分销的成本将由亿滋国际承担，该公司将负责每年分销破碎材料的业务。
