| 1. Nitrogen (N) The most important plant nutrient which stimulates growth, resulting in greener leaves, more flowers and increased fruit yields.
A deficiency results in:
- Yellowing leaves
- Stunted growth
- Premature fruit ripening
Organic fertilizer:
Compost and farm / stable manure |
 |
2. Potassium (K) Vital for photo-synthesis (the plant's food making process), it improves the quality of stems, flowers and fruit, and promotes a resistance to temperature extremes.
A deficiency results in:
- Scorched leaf edges
- Poor fruit color and flavor
Organic fertilizer:
Manure, woodash and Condi's crystals |
|
3. Phosphorus (P)
Absorbed during the early stages of plant growth, it stimulates root growth and the generation of flowers, seeds and new shoots. It also encourages winter hardiness in plants.
A deficiency results in:
- Restricted growth
- Poor germination
- Undersized flowers and fruit
- Purplish/blue tinting of leaves
Organic fertilizer:
Bonemeal and rock phosphate
