Look at the 2nd item, the "Micronized Mycorrizal Inoculant (BEIM)" on this page :
http://www.bio-organics.com/Mycorrhizae_Products.html
'Mirconized' means it is small enough to be dissolved and sprayed out of a pesticide-free backpack sprayer or whatever...any mycorr spores shouldn't be applied with chlorinated water though; the chlorine can and will damage the spores...so "hose end" sprayers are out if you're in an area where the water's chlorinated.
For my continued trials, I bought two 3 # bottles last summer at $87 each.
(From the website) : One 3# bottle covers 6400 sq ft of turf.
$87 / 6.4 = $13.59 per 1000 sq. ft.
(The 'trail size' of Micronized endomycorr works out to $15/ 1000....not bad!)
Now let's take the Grolife scenario:
"A 20-lb bag of granular costs $55 and in practice covers 2,000 square feet in a turf seeding project."
$55 / 2 = $27.50 per 1000 sq.ft.
But obviously...the Grolife is in easy 'ready to use' bags, and there's value there for many people.
I had to invest in a brand-new Solo backpack sprayer, about $70 off the internet, to designate just for micronized mycorr application because I was paranoid that the pesticide residue in the other ones I own would do some harm to the spores.
In the long run, the extra peace of mind has been worth it to me, though.
