Hi Vern,

Yes, I do. My potting mix (Premier Pro-Mix Organic Ultimate) is
pre-inoculated with AMF, but I also use powdered AMF inoculum. The
brand is Mykes, I do not know if it is available in the US. I inoculate
pretty much everything, including potatoes, except chenopod (beets and
friends) and brassica, since these do not form association with AMF.

With most transplant, we "dip" the root ball in a plate of inoculum we
carry along when transplanting. It's a bit troublesome, and it make
transplanting slightly longer.

With peas and beans, which we sow my hand, we put the seeds in a jar
along with AMF and rizobium inoculum and a spoonful or two of water, and
shake to coat the seeds.

I chit (green sprout) potato seeds, which I plant by hand. We quickly
dip the seed potato into a plate of inoculum before dropping it in the
trench.

Carrot and green onion are the only two crops that would benefit from
AMF that I do currently inoculate, because they are directly sown. I
could add the inoculum in the seed hopper, but I would not want my
pricey Jang to jam because of that.

I had very good yield last year, which was my first season. I have not
made side-by-side comparison with non-inoculated crop, so it hard for me
to judge whether AMF inoculation actually improve yield. But since the
inoculum is fairly cheap (about 20$ for the season), and since it is not
much trouble, I do it on faith.

I weed mostly by hand and with a hoe and a wheel hoe. It's pretty
shallow, so I do not think I disturb the AMF much when weeding. I do
rototile though, and that must be pretty hard on the fungus population.

From what I gather, the benefit of AMF inoculation is inversely
proportional to the soil available P. My soil has a fairly good P
level, so perhaps I am doing all that for not much. At some point, I
will stop pro-actively inoculating, and assume AMF will be well
established in my parcel. I guess, I will inoculate when growing on new
parcel, and that's it.

Hope that help!

Etienne
