- Abstract:
- The discovery of narrow microscopic tubular pores in mineral grains of podzolic soils has challenged conventional views on mineral weathering in forest soils. It has been hypothesised that these 'micropores' are formed by mycorrhizae, since the pores are the same size and are frequently occupied by hyphae. This raises questions as to what extent weathering is controlled by the interactions of mycorrhiza, trees and their nutrient demands. Previously, we have shown that ectomycorrhizal fungi can excrete large amounts of low molecular weight organic acids (LMWOAs). We hypothesise that LMWOAs significantly contribute to mineral weathering and micropore formation. We propose to study LMWOA dynamics in soil columns with/without trees and mycorrhiza in which plant nutrient demand will be controlled by manipulating P supply. The rate of weathering, LMWOA dynamics and micropore re-colonisation will be monitored.
