Fertilisers
Types of fertilisers
Macro Nutrients
Macronutrients such as Nitrogen (N), Phosphorus (P) and Potassium (K) are required by the plant
​
-
Nitrogen
-
Promotes growth of leaves of the plant
-
-
Phosphorus
-
Promotes the formation of lateral and fibrous roots
-
Promotes flowering
-
Increases the strength of plant stems
-
-
Potassium
-
Promotes formation and enlargement of fruits
-
Increases disease resistance
-
Organic vs Inorganic
Organic:
-
Release nutrients gradually (Prevents over fertilisation which is harmful to plants)
-
Improves the structure of the soil and increases its ability to hold water and nutrients
-
Little to no risk of toxic build-ups of chemicals and salts that can harm the plants
-
Renewable, biodegradable, sustainable, and environmentally friendly
Inorganic:
-
Nutrients are available to the plants immediately and improvements can occur in days
-
Highly analysed to produce the exact ratio of nutrients desired
-
Standardised labelling makes ratios and chemical sources easy to understand
-
Relatively inexpensive
