# VRA Seeding and Nitrogen Maps from Plant Available Water and Organic Matter

Build variable-rate seeding and nitrogen maps using Plant Available Water (PAW) and Organic Matter (OM), then export them directly to John Deere as a Work Plan for seamless in-field execution.

{% hint style="success" %}
The starting point is having a Soil Scanner dataset (or equivalent) with data layers for Plant Available Water (nutzbare Feldkapazität) and Organic Matter.
{% endhint %}

## VRA Nitrogen Map alongside the Seeding Map

Below, you’ll find an interactive *multi-language* guide showing how to create a VRA nitrogen map for corn based on Organic Matter (OM) data from the Soil Scanner dataset.

{% hint style="success" %}
"Usually, the first nitrogen application provides roughly 40% of the corn crop’s total nitrogen needs.

## Send Both Maps in One Work Plan to John Deere.

Below, you'll find an interactive *multi-language* guide showing how to create a John Deere Work Plan that contains both the seeding and nitrogen maps in one operation.

# 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/agronomy/vra-seeding-and-nitrogen-maps-from-plant-available-water-and-organic-matter.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.
