- •
Root, mycorrhizal and heterotrophic respiration were quantified in an apple orchard.
- •
A modified trenching method and 13C natural abundance technique were used.
- •
Mycorrhizal contribution to soil respiration was similar to that of roots.
- •
Roots significantly increased Rsom+myc in late summer and autumn.
