In a model that incorporates cropping patterns and soil types, the capture of yield and cereals dry matter is typically done through the following steps:
1. Crop selection: The model considers the specific crops that are being grown in the area of interest. This could include various cereals such as wheat, rice, maize, barley, etc.
2. Cropping pattern: The model takes into account the cropping pattern or rotation followed by farmers in the region. This includes the sequence and timing of different crops grown in a particular field or area over a specific period. The model may consider factors such as crop duration, planting and harvesting dates, and intercropping practices.
3. Soil types: The model incorporates information about different soil types present in the area. Soil types can vary in terms of their physical and chemical properties, which can significantly influence crop growth and productivity. The model may consider parameters such as soil fertility, water-holding capacity, nutrient availability, and drainage characteristics.
4. Crop growth simulation: Based on the selected crops, cropping pattern, and soil types, the model simulates the growth and development of crops over time. It considers factors such as temperature, rainfall, solar radiation, and nutrient availability to estimate crop growth stages, biomass accumulation, and yield potential.
5. Yield estimation: Using the simulated crop growth information, the model estimates the final yield and dry matter production of cereals. This can be done by considering factors such as crop-specific yield equations, crop-specific response to environmental conditions, and management practices.
6. Validation and calibration: The model's outputs are validated and calibrated using field observations and experimental data. This helps ensure that the model accurately represents the actual yield and dry matter production under different cropping patterns and soil types.
By integrating cropping patterns and soil types into the model, it becomes possible to capture the complex interactions between these factors and accurately estimate yield and cereals dry matter production. This information can be valuable for decision-making in agriculture, such as optimizing crop rotations, selecting suitable crops for specific soil types, and assessing the impact of climate change on crop productivity.
