Association Soil organic matter and leaf zinc concentration correlated with improved bean yield.
Intervention effect Manure had no significant effect on mycorrhizal spore numbers.
Observation Root colonization increased from under 5% at day 21 to 58% at day 56.
Intervention effect Manure or composted manure increased root colonization relative to untreated subsoil; topsoil had the highest colonization.
Intervention effect Topsoil promoted the greatest early colonization and zinc uptake.
Intervention effect At day 56, manured subsoil gave zinc absorption equal to topsoil and above the subsoil control.
Observation Compost manured subsoil did not show the increased zinc uptake.
Intervention effect Composted manure decreased bean root and shoot weight.
Association Uptake of other nutrients was unrelated or negatively related to mycorrhizal infection.
Mechanism Manure-stimulated mycorrhizal colonization could explain higher bean yield and zinc in manured subsoil.
