Is enhanced rock weathering part of the solution to net zero cocoa farming?

该项目的重点是调查巴西/印度尼西亚可可（Theobroma cacao L.）生产中的战争遗留问题。可可通常生长在高度风化、营养贫乏的酸性土壤（氧化土壤）上。这些土壤是贫瘠的，因为pH值低，钙（Ca）、镁（Mg）和钾(K)含量低，但铝（Al）含量高。巴西/印度尼西亚土壤的温暖气候条件非常适合利用剩余物清除二氧化碳，并产生农业和土壤的共同效益。在先前对马来西亚玄武岩修正过的土壤中种植的可可进行研究的基础上，本项目的中心目标是严格评估在三个生长季节的田间条件下，在可可上部署ERW，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。亿滋国际将为学生提供广泛的后勤和技术支持，帮助他们建立、获取和运行这些实地实验。玄武岩供应、运输和分销的费用将由亿滋国际承担，亿滋国际将承担每年分发破碎材料的业务。

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.
