Last year,  I solar cooked up big batches of "weed soup", simmered weeds and lawnmower clippings in water for 8 hours at a time.  Then I used the solids as mulch and diluted the "soup" at 1 in 20  and used it when I watered my plants.    The soup contains, sugars, minerals,  scents, some cooked weed juice, etc.   When you compare it to "compost tea" , which is better for the soil and more natural?   After all, the sugars from the weed soup are available right away to the soil bacteria, and they get a boost right away.    Compost tea probably doesn't have any energy in it.  Just bacteria and humic acid and some minerals. So what boost do the soil bacteria get?  As I look at it, they get competition and the ph drops.  I don't think that is necessarily good.  Meanwhile,  with the weed soup,  I am pretty sure there were extra flushes of mushrooms when I used it regularly when watering.   So, I was thinking,  could solar steamed weeds,  or maybe blackberry stems, act as a sterile substrate for mushrooms? Maybe brushwood,  solar steamed might work too?  Or perhaps make the logs short enough to steam in the solar cooker,  then add the mushroom spawn,  so that the edible mushrooms have no competition?     Last year,  I was doing  7 liter batches of weed soup or soil, and a batch took the whole day.  This year,  I managed four 12 liter batches of solar cooked soil one  day. (Maybe 3 batches is a realistic goal).   (Better solar cooker this time round).  Steaming weeds for growing mushrooms probably should just be steaming so just a little water.   Does anyone grow mushrooms in sterile substrate,  might you give some input?

Hands down the compost tea is better.  

Though what ever is easiest for you would be better than nothing.

Here is an older thread that you or others might find interesting:

Anne,  How do you know?   Have you done side by side tests?   Also, compost tea,  you have to make compost, then soak it,  so that takes 3 months at least.   The weed soup, you just make the soup, and you can use it the next day.  I use the solids from the soup as mulch, and I can use the mulch the next day too.   Compost (and compost tea) is like withdrawing nutrients from your gardening bank account,  letting them devalue in the compost heap,  and returning them 3 months or 9 months later with a whole new set of invading bacteria.  I think the weed soup thing is more likely to give your soil bacteria a jump when they need it.   Compost tea is more like a halfway house to chemical fertilizer.   That is my take.

Hey Brian, that thread Anne linked to has some really good stuff in there where people have tried different options involving cooking, fermenting and then composting. Have a read!

(personally, I wouldn't boil it because I'm always trying to keep the microbiota alive, and boiling is a great way to kill everything, so I just let stuff ferment in water like comfrey tea, usually it takes 2 weeks. But I'm not growing mushrooms, so my needs are different from yours.)

I utilize both compost tea and plant tea, generally for the same purpose even though they might have different mechanisms of action.

I first started using plant tea after watching a David the Good video.



I view both teas as a quick nutrient application. I am unsure if it is from soluble nutrients found in the originating matter being put into water or if it is the bacteria that thrive in the watery mix, but my plants have had positive growth from both. I believe that you may be getting different nutrient profiles depending on what you are sourcing for your tea material (Compost or plants) but the idea is similar. The water acts as a vehicle for plant food to get to the roots.

Oh, that isn't the same thing.  My plants are cooked,  and generally not fermented,  I try to use the water fairly quickly.   The sugars and carbohydrates still have their full energy and can be used aerobically by soil bacteria.  That is more bang for your buck. Aerobic bacteria do things faster than anerobic bacteria too.  And there is no stink.  Some weeds have a very nice smell,  except maybe Daphne and Laurel.  In Ireland, it rains a lot, and farmers noted that when they  had successfully made hay and taken away  in one part of the field,  and then it rained and they had to wait a few days,  the grass grew much faster under the wet hay.  Why? The science guys got interested.   Someone researched it and discovered that the rain washed sugars into the ground, boosted the bacteria and the grass grew faster.  No need to compost them,  just chop them up, and cook the weeds a few hours,  and you will get a similar effect.

I see your point, the soup will have less loss in carbon and nitrogen compared to the same starting materials composted. Besides, boiling breaks down large biomolecules into smaller ones easier for microbes to utilize. Since you have basically free energy for boiling, you set-up seems to work very well. Do you have an estimate what percentage of dry matter get turned into a liquidy form in this way?

I tried it last year the simple way - just weeds in a 5 gal bucket, stirred with a stick. It seemed to be working at first, but then stick stirring just wasn't cutting it anymore and the water went anoxic. The anaerobes took over and it began to emit this horribly objectionable funk somewhere between pond scum and concentrated ass. That was enough to end the experiment. It lingered too, even in a breeze. Yuck.

This year I've got an aquarium pump and air stone in there, bubbling away 24/7. Soooo much better! It's been going for a couple months now and it just smells like healthy pond/lake water. Without actively trying to sniff at it there's no smell at all.

I'm keeping it going as a kind of "perpetual stew" type of thing. Every few days I'll use about a third to half the bucket, top it back up with fresh water and add more weeds. So it's always changing depending on what's around, there's always a mix of new and old material in there and since it never empties out completely the bacterial population doesn't have to start over from scratch each time.

I have not done any experiments,  have you?  You ask for opinions and I gave mine.  I have grown in straight compost so I know those benefits.

I trust what  Bryant Redhawk has to say:

Bryant said, Quick short version: Some items are "richer" than others, for a really rich tea, use only the richest components for the compost and make sure to aerate while it brews.

Think like a computer program, garbage in = garbage out.

I would believe that instead of cooked weeds,    boiled potato /  boiled sweet potato would be a better use of the solar energy.      

Look into Korean Natural farming,   and they used cooked potato in their method along with sea salt.     It seems to break down the starches to a form that the bacteria can use easier....

I would say that feeding a compost heap with boiled potato / sweet potato would help energize the compost....

I guess one has to ask,  "What is my goal?"        and,    what is the methods that have already been proven to work?

I am a big believer in worm compost, and if you can feed the worms and make them happy the plants are happy with the worm castings.

I like your idea for using a solar cooker, but this is a straw man argument about compost teas. I could give a long, redundant explanation of soil biology that has already been provided abundantly on this forum, including in the thread provided. It also appears that information is not welcomed by the OP though, so it would be a waste of time to repeat it here.

Anyone who has made really good compost, extract or teas would not say “it has no energy in it” .Especially if looking at it under a microscope, or its effect on plant growth. It has billions of living micro organisms cycling nutrients and energy, which the plants get looped into with application. These microbes live on and in the plants, greatly improving their ability to access and cycle nutrients, water and energy.

Best  practices encourage using extract for soil soaks, and aerated teas primarily for foliar application. The main benefit of bubbling is the glomulin (natural glue) that helps it stick to foliage. Extract has higher diversity, which is the main benefit from compost in improving nutrient cyclin through a kore diverse soil ecosystem. Your weed tea would be a great thing to then feed these diverse microbes. Also, we want more fungi in almost all gardens, and bacteria are not bad but are more the building blocks and food sources for more complex life than an end in themselves. Weed tea after boiling will mainly be bacteria food.

So many “scientific studies” use poorly made compost that is then put into incorrectly made compost tea. The results are used as “proof” that the chemical fertilizers made by the funders of these “studies” are better than compost tea. I am sure your weed tea is better than chemical fertilizers, and surely less harmful. It would even make a great addition to compost tea or a newly made pile.

As for off-gassing, and runoff of nutrients, Johnson Su composting under large trees, with woodchips or char capping and around the bottom of the pile will contain a substantial percentage more than hot, turned compost. Boiling that tea is killing the soil life on and in the plant used to make it, making them, as you said, bacteria food. This is good for brassicas, amaranths, and other weedy species, but will need to be consumed and cycled through more complex life to benefit most other plants we want. Compost is a source of this diverse life. I would encourage learning to compost and brew extracts and teas well, and use them together with your weed tea. I would still question the benefit of boiling versus fermentation.

I have been using David's method for some time,  I call it "artifical cow"  method as the results  do smell like cow manure...

It is very close to Korean Natural Farming.

   Hi, Ben.  My argument is correct,  there is more biological energy (carbohydrates, etc.),  in the weed soup than in compost tea,   if you boil chopped up weeds,  juice is extracted from the weeds,  (just as spider mites, and aphids extract plant juice to live) and also some complex organic compounds get broken down and become part of the weed soup.  If you dilute weed soup and use it when you water your plants,  you are feeding the bacteria that are already there in the soil. No new bacteria needed. They will use the carbohydrate to multiply.  Protozoa already in the soil will eat the bacteria, worms will eat the bacteria,  die, decompose and nutrients will be released in forms available to the plants.  I think that fungi will especially benefit from weed soup carbohydrates, especially because they are already broken down somewhat.    So, yeah,  garden soil already contains a vast number and variety of bacteria and fungi.  It is easier to feed the ones that are there than to add more.   I don't know how things work with foliar applications of compost tea. People seem to be hyper critical of new stuff,   I did a compost tea brewery,  (actually have one going now),  so not sure why people think I am so against compost tea.
