# Aplicación de cal de dosis variable basada en datos de pH del suelo

Crea un mapa de prescripción Rx de cal de dosis variable a partir de escaneos de pH del suelo, valida la rentabilidad y luego expórtalo como SHP/ISOXML o envíalo a una máquina mediante integraciones.

## Crear un mapa de receta (Rx) de encalado de tasa variable (VRA) a partir del pH del suelo

Convertir los datos de pH del suelo en un mapa de aplicación de cal listo para máquinas (receta Rx). Úselo para aplicar cal solo donde el ROI sea positivo.

### Ejemplo económico (VR vs tasa fija 7.000 lb/acre)

Este ejemplo compara cal a tasa variable frente a una tasa fija única en todo el campo. Úselo como una verificación rápida de cordura antes de exportar la Rx.

| Elemento                         | Valor                    |

| Tasa promedio aplicada           | **6,348.2 lb/acre**      |
| Precio de la cal                 | $**0.02 / lb** (\~$40/t) |
| Cal total (calc)                 | **523,853 lb**           |
| Costo del material (campo)       | $**10,477**              |
| Costo del material (por ha)      | **\~**$**309/ha**        |
| Ahorro vs 7,000 lb/acre (total)  | $**441.9**               |
| Ahorro vs 7,000 lb/acre (por ha) | **\~**$**13.0/ha**       |

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.geopard.tech/geopard-tutorials/esp/agronomia/aplicacion-de-cal-de-dosis-variable-basada-en-datos-de-ph-del-suelo.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
