Nutrient requirements

The nutrient requirements of trees are low in comparison with agricultural crops. Trees planted on certain soil types however can develop nutrient deficiencies resulting in slower growth and reduced timber yields in the future.

Walk your forest regularly and check for common symptoms of nutrient problems:

  • Changes in tree colour
  • Reduction in shoot growth
  • Reduction in needle length/leaf size
  • Die-back of top or side shoots
  • General reduction in vigour

Remember that other factors can produce symptoms in trees similar to those caused by nutrient deficiencies such as poor drainage, exposure, frost and vermin damage. Always identify the cause of a growth problem before trying to rectifying it!
