GDU Calculator ● Live

Auto-fetches real growing degree units from a planting date and location, tracks corn & soybean stage, projects black layer, and flags first-frost risk. The most-used tool on AGSIST.

Option A — iframe (simplest, most robust)

<iframe src="https://agsist.com/embed/gdu"
        title="AGSIST GDU Calculator"
        style="width:100%;max-width:480px;height:560px;border:0"
        loading="lazy"></iframe>
<p style="font:600 11px sans-serif;text-align:right;max-width:480px">
  <a href="https://agsist.com/gdu-calculator">Powered by AGSIST</a>
</p>

Option B — script (auto-resizes, adds the link for you)

<div data-agsist-widget="gdu"></div>
<script async src="https://agsist.com/embed.js"></script>

Rolling out

Crop CalendarSoon

Corn & soybean growth-stage reference with GDU thresholds and management notes.

Daily Briefing StripSoon

A compact headline + takeaway strip from the AGSIST Daily morning briefing.

A note on the link. The script option places a real “Powered by AGSIST” link in your page. I’d appreciate you keeping it — it’s how a free tool stays free. The iframe option includes the same suggested link below it. Either way, there’s no tracking of your visitors beyond standard, anonymized usage stats on the tool itself.
