What does overfertilised mean?
Overfertilised describes soil, water, land, or other material that has received too much fertiliser or nutrient enrichment. The term is especially common in agriculture, horticulture, and environmental science, where excessive nutrients can cause problems such as rapid, uncontrolled plant growth, soil degradation, runoff into waterways, and algal blooms. In ordinary conversation, it may also mean excessively treated or enriched, although those broader meanings are less formal. The adjective is the British spelling of overfertilized, and it is usually hyphenated when it appears before a noun, as in overfertilised soil. It is most useful when describing a condition that is clearly beyond an appropriate or beneficial level rather than merely describing ordinary use of fertiliser.

- Excessively fertilized, especially soil or water enriched with nutrients beyond what is beneficial or sustainable.

Overfertilised land can look exceptionally productive while quietly creating runoff, algal blooms, and long-term ecological damage.
