## Транскрипт

### <Untitled Chapter 1> []

nice tea brewer right this is i told him to you know you have to have the aeration from the bottom and uh then you know put the compost tea going from the top oops compost tea in the top so this is their aerator it's some of that um irrigation tubing that you know just the water comes out of it i can't forget i forget what it's called poly pipe yeah and it at the first hebrew all of the organisms get inside that um you know it's like kind of like a fiberglass material and it goes anaerobic in there you're gonna make a tee where you have to hold your aeration unit down on the bottom of the tank using rocks and uh and bricks

### Adding to the Compost Tea [0:45]

what are you adding to the compost tea when you put that brick in there with i don't know what is that bird um not a good idea what kind of biofilm is going to form on those yeah bad and nasty so they changed it they put this is just pvc pipe with holes in it and then look at these rebar foods so here's some of the foods we've talked about humic acid complex proteins kelp real good source of fungal foods oatmeal bran fish hydrolysate anything that has a wide carbon and nitrogen ratio and then bacterial foods the simple stuff you know apple juice with fungi you would want the pulp of the apples with the juice squeezed out so you know some pretty simple things that we probably have on farm that could be used as fungal foods versus the bacterial foods simple sugars complex sugars

### Temperature [1:54]

so temperature slower growth when it's colder you're gonna have to brew longer as it warms up um you'll be brewing for a shorter period of time so if you're at 72 degrees or higher you're gonna brew for somewhere between 20 to 24 hours as it gets cooler less than 72 degrees you're going to be brewing for longer so say at 55 36 hours if we're getting down to 45 degrees you're going to brew for 20 for 48 hours how do you know when your hebrew is actually finished you should not be able to smell any of your starting materials that you added the fish hydrolysate smell should be gone the smell of the kelp should be gone you can be looking at your organisms and making sure that way as well just make sure that when you get to high temperatures remember the organisms are going to grow faster higher temperature they're going to use up the oxygen faster so as it gets hotter we need to use less food the hotter it's getting start dropping back on your foods because we don't want these organisms to grow so fast that they're using up all the oxygen and you go anaerobic so typically when we get to a temperature of 100 degrees you don't add any foods because you can't keep up with the oxygen demand of these organisms so let me show you a little data try to not make this too boring we're looking at oxygen so the red line is the oxygen and we are actively aerating we're bubbling so this is going on at a pretty good clip this the high on this the maximum oxygen concentration that can exist in your water depends on temperature and on barometric pressure the higher you are the less oxygen is present your barometric pressure is lower so if you're brewing at a mile high you're probably not going to be putting more than just a couple teaspoons even in a 500 gallon brew because you're already at fairly limited oxygen conditions the hotter it gets the less oxygen can be in your air so again hotter it is you can't have as much oxygen so here we are this was um in colorado where about a mile high and it was a fairly warm date so maximum

### Maximum Oxygen Concentration [4:37]

oxygen concentration is eight parts per million where do you find what this what when you're brewing some place where do you find the data to tell you what's your maximum it's the usgs the geological service survey and you go to their website and you type in oxygen concentration with temperature and elevation and bang it'll take you right to the table so you find out what your elevation is you look at what your temperature is and there's your maximum oxygen concentration that's where you could start from we're putting the biology into that water and so of course right at first not a lot of activity the organisms aren't growing really fast yet we've just diluted our organisms in a lot of water so they're not very concentrated but of course we've put foods in here so they start growing and watch the activity take off as these organisms start growing really fast they're finally starting to affect the oxygen concentration the aeration rolling boil on the surface of our tea brewer and yet these organisms are growing so fast they're growing using up oxygen faster than we're diffusing oxygen into the water whoa so we keep growing they keep growing keep growing they finally run out of food and then you will see the activity levels start to drop did this tea brew go anaerobic well the threshold

### Threshold for Anaerobic Conditions [6:16]

for anaerobic conditions is six parts per million oxygen or six milligrams per liter and so here we are there's the threshold above this we would consider it aerobic below that anaerobic it's not that i mean it's not actually like that as you step over the line everything goes anaerobic no it's a threshold so but as that oxygen concentration is being used up by these organisms growing faster and faster yes this tbr went over the edge into anaerobic conditions all of our beneficial organisms had to go to sleep they went dormant or they died so we had a lot of death of the beneficial organisms some of them went to sleep some of them managed to go dormant fast enough and our anaerobic organisms started to grow look at the fact that this is going from like 15 hours to 20 hours full five hours of anaerobic conditions if you have e coli if you have human pathogens in the compost if you haven't gotten a really good compost then those bad guy organisms start to grow the pythium phytophthora rhizoctonia the disease-causing fungi have a chance to grow too so all of a sudden bad things are happening in here we're losing our nitrogen our soluble nitrogen as nitro as ammonia we're losing our sulfur we're making some nasty acids the ph will start to drop except the organisms ran out of food and so because they're not growing very rapidly anymore and we're still aerating we're still you know bubbling away oxygen starts to return into that hebrew and it comes back above aerobic and so now the anaerobic organisms die or go dormant and whatever aerobic organisms we still have left in that brew will wake up and start to grow again but it's not as good a compost tea as we could have had we've lost some really critical things so we don't want to see that oxygen concentration going too low so what do you do when you realize well either you wait till it cools off you move to a lower elevation maybe not going to work or you put in less food isn't that just the easier thing to do put in less food and so if we do that we now have less food so we take off we don't ever drop oxygen down to anaerobic conditions doesn't even come close we never lose the good guys we don't develop any ciliates we don't lose our nitrogen our sulfur our phosphorus so this is the kind of testing that we want to do what's the recipe how much food can we put in depends on how much aeration your tbr is capable of so either you're going to have to do this testing yourself or talk to the person making your tea brewer they should be able to tell you make it simple there are a number of organisms that we can add into teas when we have specific problems

### Bulvaria [9:42]

problems so bulvaria is a fungus that is parasitic on soft bodied insects bovaria grows extremely well in the tea brewer but you do not want to follow the manufacturer's recommendations on the outside of the container do not follow their directions you need a pinch of bovary into a 500 gallon brew you would put a pinch of the bovario spores that come in the container a pinch goes in every single one of those approximately a billion spores that you just added into your tea brew every one of them will germinate at the end of the 24 48 hour t brew those bavaria are going to be looking for soft bodied insects to wipe out and they are very good at doing that be a little careful with bovaria do not be using bovaria when you want to have bees around okay don't put it out at pollination time because the bovaria will take out your bees so careful put it use the bovaria only when you have a soft biting insect wiping out your crop it is a bio control agent um trichoderma gliocladium our fungi that attack and parasitize other fungi so you've got a mildew outbreak happening take a pinch of the targaderma gliocladium again it's a pinch it don't follow the directions on the package so you know a little container is going to tell you put all of the spores in this thing into a quart of water and then spray out if you do that you are going to just gum up your tea brewer it's going to be thick with those fungi as they germinate and grow you only need a pinch so then you would go and apply the compost tea to the foliage where you've got the disease outbreak happening and you do this only when you're in that outbreak mode because if that trichoderma or the gliocladium if any of that tea drops onto your soil and these trichoderma gliocladium move through your soil and get to your root system where your mycorrhizal fungi are colonizing your roots these fungi attack and consume your mycorrhizal fungi and we have shown this time and time again in real world studies so you got to be careful if you have an outbreak and you choose to follow this path you're going to have to replenish your mycorrhizal fungi just be aware of that and actually it would be preferable probably just to apply the good compost tea to the surfaces of your plant and prevent the disease-causing fungus or the insect pests from finding your leaf surfaces but i like to go through these and kind of give you the be careful people can tell you oh yeah this is the way to do it but know what you're doing

### Mycorrhizal Fungi [12:51]

mycorrhizal fungi of course they can be added in a tea but the humic acid in compost tea will get the spores of the mycorrhizal fungi to wake up and start to grow so you don't want to be put mycorrhizal spores in at the beginning of the brew cycle because your mycorrhizal fungi will all be dead at the end of your brew cycle so you put the mycorrhizal spores into your compost tea just before you're going to spray it out just before you inject down into your root zone and get that tea left in the area around your root zone in the springtime with your seeds soak your seeds in a mix of the your compost tea with the mycorrhizal spores so take all the seeds that you're going to be planting put them into the compost tea with the mycorrhizal spores attached to organic matter instantly and they're glued there they're stuck there now so they're on your seed surfaces all the microorganisms inside the seed coat in the cracks or crevices 15 minutes take those seeds out you don't want your seeds to be imbibing and starting to germinate dry those seeds down plant them you know tomorrow the next day two or three weeks a month from now not a problem you've got the organisms on the seed surfaces you have the mycorrhizal fungi on your seed surfaces bare root soak them in a compost tea with the mycorrhizal spores so you get all of those organisms right on those surfaces plant them and your roots are already colonized with these good guy organisms here's some of the pseudomonas you've got some pesticide problems there you go let's get those pseudomonas bacillus species there's a number of biocontrol agents here that you can buy you know uh serenade is a single bacillus species that most insect pests do not like spray your plant surface the insect pests don't want anything to do with your plant yuck i'm going someplace else so a number of different bio control agents if you're interested um i can talk to you about all the rest of them if you want
