Mesocosms are large tubes (1.5 m high x 15.24 cm in diameter) used to grow maize, or rice under long-term conditions (4-6 weeks). The roots have plenty of room to grow downward. Custom media mixes are used, and parameters such as drought, high/low Nitrogen and high/low Phosphorus availability are evaluated.
