# Irrigation Water Requirement MCP > Irrigation Water Requirement Calculator determines precise water needs for agriculture, calculating crop evapotranspiration and moisture deficit across different growth phases. It tells you exactly how much water to apply and what the seasonal profile looks like for crops such as Soybeans or Maize. ## Overview - **Category:** agriculture - **Price:** Free - **Tags:** irrigation, evapotranspiration, crops, agronomy, water-deficit ## Description Figuring out water needs isn't a guess; it's math. This MCP handles complex agronomy calculations, helping farmers and consultants move beyond simple rainfall predictions. You can calculate specific growth stage demands—like determining the exact deficit when growing Sugarcane or Cotton. Need to know how much water to apply? The tool calculates required irrigation depth and volume based on accumulated deficits and efficiency rates. Plus, you get a complete seasonal view for any supported crop, giving you a full picture of its water needs over the entire cycle. Connecting this MCP through Vinkius lets your AI client run these models directly, turning complex agricultural reports into simple actions. ## Tools ### get_crop_irrigation_profile Retrieves a full, season-long chart showing the expected water needs for any supported crop. ### calculate_irrigation_event_depth Calculates exactly how deep and in what volume you need to irrigate based on current water deficits. ### calculate_phase_demand Determines the specific water demand and moisture deficit for a crop at its current growth stage. ## Prompt Examples **Prompt:** ``` What is the water demand for Soybeans in the Initial phase if I have 10 hectares and 5mm of rain? ``` **Response:** ``` The water demand for the Initial phase of Soybeans is 12 mm, which corresponds to 120 m³/ha. The water deficit for this period is 7 mm. ``` **Prompt:** ``` I have a deficit of 15mm. How much irrigation depth do I need with 80% efficiency? ``` **Response:** ``` To compensate for a 15 mm deficit with 80% efficiency, you need an irrigation depth of 18.75 mm, which is 187.5 m³/ha. ``` **Prompt:** ``` Show me the growth stages for Maize. ``` **Response:** ``` The Maize profile includes the following stages: Seedling, Development, Tasseling, and Grain-fill. ``` ## Capabilities ### Calculate growth stage water demand Determines the precise amount of water and moisture deficit for a crop during a specific phase. ### Determine irrigation volume needed Calculates the exact depth and volume of water required to compensate for current deficits, factoring in application efficiency. ### Retrieve seasonal water profiles Generates a complete overview of water requirements for an entire growing season for any supported crop. ## Use Cases ### Pre-season planning for Maize A farm manager wants to know the full scope of water management for their entire field. They ask their agent to run get_crop_irrigation_profile on Maize, which immediately provides the complete seasonal water requirement overview, allowing them to secure early water permits. ### Responding to a sudden dry spell An agronomist notices low soil moisture. They use calculate_phase_demand for Coffee during its flowering phase, which tells them the immediate water deficit and how severe it is right now. ### Optimizing current irrigation cycle A team needs to know if a planned watering session is enough. They input their measured 15mm deficit into calculate_irrigation_event_depth, and the tool returns the required volume for 80% efficiency. ### Comparing crops before planting A consultant needs to advise a client on which crop is best suited for the coming dry season. They run get_crop_irrigation_profile for both Cotton and Sugarcane, comparing their full seasonal water demands side-by-side. ## Benefits - Stop wasting resources. By using calculate_irrigation_event_depth, you get a precise volume needed to cover deficits, so you don't overwater and waste energy or money. - Know what's coming next. Running get_crop_irrigation_profile gives you the entire season's water roadmap at once, letting you plan for dry spells weeks ahead of time. - Target your inputs precisely. The calculate_phase_demand tool locks down the water requirements during critical periods, like when Soybeans are developing their pods. - Save hours on spreadsheets. Instead of cross-referencing tables and calculating evapotranspiration by hand, you let your agent run these complex models instantly. - Improve yield estimates. Accurate deficit modeling helps you advise clients on optimal timing for intervention, directly impacting potential harvest size. ## How It Works The bottom line is that you get actionable data on exactly how much water your crops need, when they need it, and why. 1. You provide the tool with key inputs, like the specific crop type (e.g., Maize), the current growth phase, and local weather data. 2. The MCP runs complex agronomic models to calculate evapotranspiration, water deficit, and necessary adjustments for irrigation depth. 3. Your AI client delivers a clear report showing both the immediate demand and the overall seasonal water requirement profile. ## Frequently Asked Questions **What crops does the Irrigation Water Requirement Calculator support?** It supports major crops like Soybeans, Maize, Sugarcane, Coffee, and Cotton. The profile data is available for all listed types. **Does calculate_irrigation_event_depth only calculate volume?** No, it calculates both the required depth (in mm) and the corresponding volume needed per hectare, factoring in application efficiency. **How do I get a seasonal view of water needs using get_crop_irrigation_profile?** Just input your crop name. The tool provides a complete profile that charts the expected water usage across all major growth phases for the season. **Can calculate_phase_demand tell me if I need to irrigate now?** Yes, it calculates the specific water deficit during a phase. This figure is critical input data used by calculate_irrigation_event_depth to determine immediate action. **Is this MCP just for soybeans?** No, it's designed for multiple crops. It handles the complex calculations necessary for various types like Maize and Cotton as well. **How do I calculate the water deficit for a specific crop stage?** Use the `calculate_phase_demand` tool. You will need to provide the crop type, the phenological phase, the area in hectares, and the effective precipitation recorded during that period. **Can I calculate the volume of water needed for irrigation?** Yes, by using the `calculate_irrigation_event_depth` tool. It calculates both the required depth in mm and the volumetric requirement in m³/ha based on your accumulated deficit. **Which crops are supported by this tool?** The tool currently supports Soybeans, Maize, Sugarcane, Coffee, and Cotton.
