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
