Etymology: The word is a plain compound: "agro-" joined to "chemistry." The first part comes from Latin "ager," meaning field or land, which traces back through Proto-Italic "agros" to a very old Indo-European root meaning a field or open ground. That root is the same source that gave Latin its word for land, and English has long used "agro-" as a combining form for anything connected with farming or cultivated land. "Chemistry" has a longer and more winding path. It descends from Ancient Greek "khumeia," a word for the art of metal-working, mixing and alloying, which passed into Arabic as "al-kimiya" and then into medieval Latin as "alchemia." Those forms gave rise to the word for the practical study of substances, and the modern "chemistry" took shape in English from that base. Joining the two produces a term for applying chemical knowledge to farming, a field that became prominent in the twentieth century as fertilizers and pesticides grew in importance. The compound is a modern coinage built from older parts, so its meaning is transparent: chemistry in the service of agriculture.
