Brief description Carbon costs of plant nutrient and water uptake. This project aims to investigate how much carbon plants need to invest belowground in return for water and nutrients. By using economic principles of supply and demand the project will quantify carbon expenditure for water and nutrients in grasslands and crops under different climate and land management scenarios. This project will use triple and quadruple isotope labelling techniques and explore the dependency of carbon investment on plant-microbial interactions and availability of belowground resources. Expected outcomes include new knowledge to build a universal framework about plant carbon-water-nutrient economics. This will benefit global carbon cycling models and efforts to increase nutrient and water use efficiencies in agricultural crops.
