- •
Soil organic carbon (SOC) and aggregate stability were greater and basal soil respiration (BSR) was lower in finer soils.
- •
Increasing plant residues significantly increased SOC, BSR and aggregate stability.
- •
Treating soils with endophyte-infected (E+) residues increased SOC and aggregate stability.
- •
E+ residues decreased BSR due to toxic effects of phenolic compounds on microbes.
- •
Tall fescue residues (especially of E +) enhanced SOC storage and aggregate stability.
