How to Improve Soil Fertility
Before adding nutrients or improving your soil you must first assess your soil to determine its condition. Use a basic soil test kit to determine the soil NPK status & soil pH status.
Once you know your soil's condition you can add the relevant nutrient
- Soil is low in Potassium - Add Sulphate of Potash
- Soil is low in Phosphorus - Add Super Phosphate
- Soil has low pH (Acidic) - Add Garden Lime
- Soil is Low in all NPK - Add a General fertilizer, Chicken manure, Farm Yard Manure
Why we add nutrients
- Some soils lack vital nutrients such as NPK & others
- Nitrogen is important for leaf growth
- Phosphorus is important for good root growth
- Potassium is important for fruit & flower development & disease resistance
- Below are some options for improving your soil's fertility
Farm yard manure
- Must be well rotted, therefore at least 12 months old
- Manure has a moderate fertility
- It also improves soil condition & drainage abilities
How to add
- Dig trench, add 4 inches to base of trench
- Alternatively add 4 inch to surface of soil & work into soil using fork
Manure pellets
- Easy to handle
- High in Nitrogen
How to apply
- Divide your plot into 1M2 sections
- Use garden twine to divide out sections
- Add 150g per M2
Super Phosphate
- Straight fertilizer
- High in phosphorous
How to apply
- Divide your plot into 1M2 sections
- Use garden twine to divide out sections
- Add 35g per M2
Growmore
- General or multi purpose fertilizer
- High in all NKP
How to apply
- Divide your plot into 1M2 sections
- Use garden twine to divide out sections
- Add 100g per M2
Sulphate of Potassium
- A straight fertilizer
- High in Potassium (K)
How to apply
- Divide your plot into 1M2 sections
- Use a garden twine to divide out sections
- Add 35g per M2
