I understand that Michele Amari, in Storia dei Musulmani, mentions al-'Awwam's Kitab al Falaha, in reference to a particular method of onion growing around Palermo. Does Peter Lord's 1979 partial translation of the Kitab mention this particular information? I'm just trying to see if there's a more available translation of this particular piece of information than Amari's 19th century, many-volume opus. I am not sure if the available Spanish or French translations have this information at all.  Thank you in advance for any insights you can offer.
