The maintenance of satisfactory nutrient levels in growing trees is an important part of good forest management.
The most important nutrients in forestry are phosphorus, nitrogen and potassium. Phosphorus is of fundamental importance from an early stage for good root development. Both nitrogen and potassium are important for photosynthesis.
Nutrient problems can sometimes be hidden and not immediately visible in established forests so make sure to tackle potential nutrient problems in good time.
The appropriate time to take foliar samples for broadleaves and larch is August.
