As this is my very first post to this forum, I must apologise in advance if I'm in the wrong place, so please correct me if so.
I'm investigating the cultivation of Tubar Melanosporum on our smallholding in South Africa, to start with it will be only one hectar.
I'm doing extensive research and have come against a brick wall in on area, (I'm sure Ill hit a few more).
The area I have selected where I hope to establish my orchard currently has several non indigenoustrees on it, they are three Pinus pinea and two Eucalyptus globulus, all are mature trees.
Whilst removing the trees would be easy I'm very concerned that the spores of their host mycorrhiza will remain and can later infect the planted host trees.
My question is: Is there a way to chemically eradicate any traces of these existing mycorrhiza, (after the removal of the invasive trees), that will decompose over time so that when I plant my inoculated trees will not affect their mycorrhiza and have created a "vacuum" so that there will be no fungal competition and thus promote growth.
I will need to plow in about 70 tons of lime in order to raise the PH so I could make additions at this stage.
