also: かねごえ
noun
Refers to industrially produced fertilizer, as opposed to natural or organic fertilizers. The term is somewhat technical and may be encountered in agricultural contexts.
農家は金肥を使って収穫量を増やした。
The farmer used chemical fertilizer to increase the harvest.
金肥の過剰使用は土壌を劣化させる。
Excessive use of chemical fertilizer degrades the soil.
Rare kana spelling for the reading かねごえ; the kanji form 金肥 is normally read きんぴ.
Compound of 金 (きん, 'money' or 'chemical') and 肥 (ひ, 'fertilizer'). The exact historical derivation is uncertain, but the term likely arose to distinguish industrially produced fertilizers from traditional organic ones.
