Wow, I've never actually seen anybody use Growmore other than me on here....must be a California thing?i rotate my microbial teas with my a and b from growmore and hit it hard with some mkp later in flower. best of both worlds
Love this! Thank you for posting!I'm not drinking the Kool-Aid. Neither did this guy. He made some good points about the study.

in regards to the study you have a link to, I believe it is flawed. When using plate count method you are growing anaerobic microbes. Plate count methodology is great for assaying human pathogens (what they were created for) however they fail to give a true indication an healthy soils microbial count and/or biomass.
Also when using plate counts the food source provided to the microbes is extremely limited. They are 000’s of different foods in healthy soil bacteria and fungi use to grow, how can we expect aerobic microbes to grow in anaerobic conditions with limited food source?
To assess soil life you need to use direct microscopy not plate count methods. Miss information can come from everywhere and I think this case the the study you are referencing.
Ha, also the organic ferts used consisted of neem cake!!!! a pesticide used to control nematodes. You think that it kills bad nematodes and not the good ones? Its clear the people running the study have know idea about soil microbiology. As someone who understands soil biology would not use neem cake as a fertilizer-pesticide combo
Who is sending out misinformation?
“The use of inorganic fertilizers resulted in low organic carbon content, microbial counts and microbial biomass carbon of the soil, although it increased the soil’s NPK level which could be explained by the rates of fertilizers being applied.”
This statement from the abstract reveals the organic carbon is depleted. This is because the over activity of the bacteria to use up all the nitrogen that was dumped in. The soil has lost humus! We all know how important humus is for soil. Bacteria need 5 carbons for everyone nitrogen so they are going to get those carbons from the humus and organic carbon rather then the plant exudates. I wouldn’t want people thinking all they have to do is correctly manage synthetic ferts and they are in the clear.
I know this article is focusing about salts not everything else I have mentioned. Thanks for writing it, I have learnt something from it too!
Cheers

Synthetic nutes are mineral nutrients, not salts. Although people call them salts they aren't the same as table salt or rock and don't have the same effect on soil or microbesBecause salt kills slugs and synthetic nutes are salts and slugs are basically big microbes.
Synthetics when you here "ate" at the end is classified as a salt like nitrates which is salt microbes make organic material and produce enzymes that convert ammonium to nitrate formSynthetic nutes are mineral nutrients, not salts.

So they are! Good shout. I just didn't want people to confuse em with the same salt as sodium chlorideSynthetics when you here "ate" at the end is classified as a salt like nitrates which is salt microbes make organic material and produce enzymes that convert ammonium to nitrate form

@Fishbulb does exactly this, Mega crop and an assortment of organic goodies
