Etymology: "Biofertilizers" is the plural of "biofertilizer", a compound built from the combining form "bio-", from Greek "bios" meaning "life", attached to "fertilizer". The fertilizer half comes from the Latin "fertilis", meaning fruitful or productive, which is also the root of "fertile." Its modern sense of an agent that supplies nutrients is a much later extension: the older meaning of "fertilize" was simply to make fertile or to fecundate. The prefix does the real work here. Its "bio-" element signals living organisms, so the compound describes fertilizers whose active ingredients are microbes rather than mineral salts or manufactured chemicals. The plural simply refers to the several distinct preparations, each built around different bacteria or fungi, that farmers and researchers use for this purpose.
