# Read the Grazing Wedge

> Each field's grass cover as a bar, worked out from the satellite, with the target and the residual drawn across.

**Before you start.** The farm has a herd on a field. [Move a Herd](/how-do-i/map/move-a-herd) puts one there.

<Steps>
  <Step title="More, then Livestock">
    Above the herds is the **Grazing wedge**, one bar per field, tallest first. Cover is in kg of dry matter per hectare.
  </Step>

  <Step title="Read the two lines">
    The dark dashed line is the pre-grazing **target**, 2,800 kg DM/ha. The amber one is the **residual**, 1,500, the cover to leave when the herd moves off. A bar under the residual goes amber.
  </Step>

  <Step title="Read the herds">
    Each herd's row shows days on its field. When its field is at the residual the row reads **Move soon** and the Move button goes solid.
  </Step>

## What You See Next

Graze the tallest bar first. The caption says where the cover came from, which is the latest satellite pass and its date. A plate-meter reading replaces it when you take one.

## If It Does Not

| You see                             | It means                             | Do                                                                              |
| ----------------------------------- | ------------------------------------ | ------------------------------------------------------------------------------- |
| No wedge                            | No field has a satellite capture yet | The first capture arrives with the next clear pass, usually within a day or two |
| A bar is missing                    | That field had cloud on every pass   | It fills in on the next clear one                                               |
| The cover looks high for the season | NDVI reads canopy, not height        | Take a plate-meter reading and record it                                        |
