| Several endomycorrhizal plant nutrient trials were undertaken from 1987-98 at Eastleigh, Forest of Dean, England. The main findings were: (1) the sterilisation of soil has a significant effect on endomycorrhizal activity and trace element uptake: (2) endomycorrhizal effect on trace element uptake varies with plant species (foodstuff); (3) addition of fertiliser and rock phosphate to soil reduces mycorrhizal colonisation and plant trace element content (except phosphorous); and (4) mycorrhiza enhances the trace element plant uptake following the addition of wood ash. |
