| 概要≠ | Crop growth models are mechanistic simulation systems designed to predict crop development, biomass accumulation, and yield under varying environmental and management conditions. DSSAT (Decision Support System for Agrotechnology Transfer) and APSIM (Agricultural Production Systems Simulator) are the most widely used platforms, developed in the 1990s-2000s to support agronomic decision-making and climate adaptation research. | Soil respiration measurement quantifies the rate at which CO2 is released from the soil surface to the atmosphere, integrating contributions from root respiration and microbial decomposition of organic matter. It is a fundamental technique in agronomy, ecology, and climate science, providing insight into belowground carbon cycling, soil biological activity, and ecosystem carbon balance. Measurements are typically made using static or dynamic chambers placed on the soil surface. |
