Effects and implications

Trees

  • Increased yields greatest where soil organic layer C:N ratio high (Guerrieri et al 2011).
  • Destabilisation; faster growth, reduced investment in roots leading to increased risk of drought stress (Anders et al 2002) and increased risk of uprooting.
  • Decreased fine root biomass and numbers of root tips, with associated increased above ground biomass, indicative of micro nutrient deficiencies induced by excessive growth.
