Also known as the law of the minimum. A law proposed by Liebig in 1843 regarding the relationship between plant growth and inorganic nutrients (fertilizers). In order for a plant to grow healthily, it needs to absorb a variety of inorganic elements in a certain ratio according to the type, but if one of these elements is lacking, the plant's growth will be poor, and even if other nutrients are abundant, the plant's growth will be controlled by the nutrient that is most lacking. Later, German agronomist Wolney (1846-1901) added and corrected this to say that of the factors necessary for plant growth, including water, light, temperature, and air, the growth of the plant is controlled by the factor that is supplied in the smallest proportion.

最少律とも。植物の生育と無機養分(肥料)の関係について,1843年リービヒが提唱した法則。植物が健全な生育を営むためには,多種の無機成分が種類に応じて一定の割合で吸収される必要があるが,そのうち一成分が不足しても生育は悪くなり,たとえ他の養分が豊富に供給されていても植物は最も不足している養分によりその生育を支配されるという説。その後ドイツの農学者ウォルニー〔1846-1901〕が水,光,温度,空気なども加えて,植物の生育に必要な諸因子中で最も供給割合の少ないものに支配されると補足訂正した。
