Feeding the crops
- To grow well, plants need certain elements from the soil — and farming removes them over time.
- Fertilisers 肥料 put these nutrients back.
喂养作物
- 要长得好,植物需要来自土壤的某些元素——而农业随时间移除它们。
- 肥料(fertilisers)把这些营养放回去。
Fertiliser route lab · 化肥路径实验室
Follow nitrogen from raw materials to crop growth. · 追踪从原料到作物生长的氮元素。
NPK fertilisers supply nitrogen, phosphorus and: · NPK 化肥提供氮、磷和:
N, P and K are the three key nutrients. · N、P 和 K 是三种关键营养元素。
The three elements supplied by NPK fertilisers are nitrogen, ______ and potassium. · NPK 化肥提供的三种元素是氮、______ 和钾。
N, P and K. · N、P 和 K。
The key nutrients
- Plants need nitrogen 氮气 (N), phosphorus 磷 (P) and potassium 钾 (K).
- Fertilisers supplying these are called NPK fertilisers.
Clean dry air is about 78% nitrogen, 21% oxygen and 1% other gases
关键营养
- 植物需要氮(N)、磷(P)和钾(K)。
- 供给这些的肥料被称为 NPK 肥料。

清洁的干燥空气约 78% 氮、21% 氧和 1% 其他气体
Nitrogen in fertiliser mainly helps plants with: · 化肥中的氮主要帮助植物:
Nitrogen is used to make proteins for growth. · 氮用于制造生长所需的蛋白质。
Why each matters
- Nitrogen: for healthy leaves and growth (making proteins).
- Phosphorus: for roots; potassium: for flowers and fruit.
Greenhouse gases absorb the heat the Earth gives off and send some back, warming the planet
为什么每个都重要
- 氮(nitrogen):为健康的叶子和生长(制造蛋白质)。
- 磷(phosphorus):为根;钾(potassium):为花和果实。

温室气体吸收地球放出的热并送回一些,使行星变暖
A benefit of fertilisers is that they: · 化肥的一个好处是它们能:
They replace nutrients, raising yields. · 它们补充养分,从而提高产量。
Excess fertiliser washing into rivers can cause eutrophication. · 过量化肥流入河流会导致水体富营养化。
Nutrient run-off feeds algal blooms that deplete oxygen. · 营养流失会助长藻华,消耗水中的氧气。
Benefits and problems
- Fertilisers raise crop yields, feeding more people.
- But run-off into rivers causes eutrophication 富营养化 (an environmental problem).
Fertilisers boost yields but can pollute water. Excess fertiliser washes into rivers, feeding algal blooms that use up the oxygen and kill fish (eutrophication). Use must be balanced.
利益和问题
- 肥料提高作物产量,喂养更多的人。
- 但流入河流造成富营养化(eutrophication,一个环境问题)。
肥料提升产量但能污染水。 过量的肥料冲进河流,喂养藻华,藻华耗尽氧并杀死鱼(富营养化)。使用必须被平衡。
You've got it
- plants need nitrogen, phosphorus and potassium — supplied by NPK fertilisers
- nitrogen → growth/leaves; phosphorus → roots; potassium → flowers/fruit
- fertilisers raise yields but excess causes eutrophication
你掌握了
- 植物需要氮、磷和钾——由 NPK 肥料供给
- 氮 → 生长/叶子;磷 → 根;钾 → 花/果实
- 肥料提高产量但过量造成富营养化
