i mix up 300 gals per watering. gonna need to collect piss at the local bar to get enough.
i was more interested in the vitamins etc not the NPK.
Piss? And B vits? Take the whole spectrum of B vits for 30 days and start to piss in a big jar/cover and store for about 10 days and mix at 25 parts water to 1 part piss.... Not a joke, but funny!
Lets see here, Most plants produce their own B-1 in amounts greater then delivered by ST.
Must be the Auxin's in ST? At the concentrations they suggest. The amount of Auxin/s would reduce limiting factors of root growth in the form of new roots forming and stretch out. This is most likely the part it played in your lawn.
Alternative's - Well, for sure the first thing that comes to mind is Kelp.....B vit's, auxin's, micro's.....Kelp has been tested and proven to increase root mass by as much as 170+% . This was done by tilling kelp meals into the soil. Yet kelp extracts act nearly the same by adding it to waterings. The claims of ST as far as it being used as a transplant agent and for root gains, is not only mimicked by Kelp but, exceeded.
Another thing that would do the same as ST,
and be super beneficial down the road.....Would be to apply a simple bio tea! Get active living bio's back into that damaged by commercial fert lawn! This is becoming a big industry in some area's of the country. Organic lawn care! I must say that with our farm brewers. I have the luxury to spray my lawn with AACT and have had infamous local "Dutch" (long story) lawn poisoners. Stop and ask just how I get my lawn so lush and weed free *see note*. When told they look at me funny and only one has asked me for some of the "tea" - He's now a big organic fan and does not use "Scott's lawn poisons" anymore...
*NOTE* Those "weed n feed" ferts that are so popular.....Contain
nothing as a "weeding" ingredient. They have fertilizers only! The idea is that heavily ferted lawns will fill out and "choke" the weeds out......That's it!
If you could find a way to brew like 50 gallons of the AACT and then apply it with some kelp extract mixed in after brewing the tea.
(do this in the spring and once in the fall) Your lawn will go fricking nuts! The now active and alive soil will utilize the left over nutrients from fert use......The lawn explodes.....Keeping it that way after a year or so is not hard....You just start adding high N organic ferts to the tea to the tea, or simply mix and spray your lawn with Age Old grow at the rate of 2 tsp a gallon. (or as my "Dutch" lawn wizard does) Use an old MG sraymixer that attach's to your hose and dump the Age Old in and spray the lawn...(He adds the Kelp extract to the Age Old in the mixer tank)...
Every spring I make sure the coarse nozzel's are in place on my lawn tractor sprayer. Fill my tank with fresh filtered simple AACT and do my lawn, then amber on over to his place and spray it too....
Kelp extract is used at 5ml per gallon for application rates.
The tea can be diluted to 50% but, I do ours at 100%.
That's about it for a replacement for ST - kelp extract.....
