Copper
- Copper is a component in numerous enzymes, many of which serve an essential purpose for the plant.
- The importance of copper in the plant is related to reproductive processes.
- “A few grams of copper” can often boost the production potential of many crops by hundreds of kilograms.
- As a rule of thumb, soils with higher humus content experience a greater Cu deficiency.
Copper fertilisation can be seen to have the most pronounced effect on:
- cereals,
- vegetables,
- fruit trees,
- legumes.
