Course lessons

1

Nitrogen

How nitrogen supports vegetative growth, proteins and chlorophyll.

2

Phosphorus

Its role in energy transfer, rooting, establishment and reproduction.

3

Potassium

How potassium regulates water balance, enzymes and crop quality.

4

Calcium

Why calcium is essential for cell walls, growing points and fruit quality.

5

Magnesium

Its central role in chlorophyll, photosynthesis and enzyme activity.

6

Sulphur

How sulphur contributes to proteins, enzymes and nitrogen use.

7

Iron

Why iron availability is closely linked to pH and root conditions.

8

Manganese

Its functions in photosynthesis, enzymes and plant defence.

9

Zinc

How zinc supports enzymes, hormones and normal shoot development.

10

Boron

Its importance for growing points, flowering and calcium function.

11

Copper

How copper supports enzymes, lignification and reproductive growth.

12

Molybdenum

Its specialised role in nitrate reduction and nitrogen metabolism.

13

Macronutrient ratios

Why the balance between nutrients can matter as much as concentration.

14

pH

How acidity and alkalinity affect nutrient availability and uptake.

15

Cation Exchange Capacity (CEC)

How soils and substrates retain and exchange nutrient cations.

16

Water quality

How alkalinity, bicarbonate and dissolved minerals affect nutrition.
