农业中氮的生物学模型是为近代早期的英国所指定的，并用于分析从中世纪到工业革命的粮食产量增长。固氮植物占产量增加的一半左右;其余的来自更好的种植，种子和排水。该模型强调了缓慢的化学反应，控制了由可转换畜牧业和豆类种植引入的氮的释放。无论英国的制度多么有效，氮的化学性质都意味着英国的农业革命将比世纪的绿色革命更加渐进。
A biological model of nitrogen in agriculture is specified for early modem England and used to analyze the growth in grain yields from the middle ages to the industrial revolution. Nitrogen-fixing plants accounted for about half of the rise in yields; the rest came from better cultivation, seeds, and drainage. The model highlights the slow chemical reactions that governed the release of the nitrogen introduced by convertible husbandry and the cultivation of legumes. However efficient were England's institutions, nitrogen's chemistry implied that the English agricultural revolution would be much more gradual than the Green Revolution of the twentieth century.
