Making Microbial Mineral Tea

The process to brew our Microbial Mineral Tea is simple. The dry ingredients are placed in brew bags and the liquid/soluble ingredients are mixed directly into the water. The basic recipes are shown in the table below:

Brewer size (in gallons) 1500 gal 1000 gal 500 gal 250 gal 50 gal 5 gal
Huma Phos 40 lbs 30 lbs 20 lbs 10 lbs 2 lbs 3.2 oz
Pretreated Humus 25 lbs 16 lbs 10 lbs 5 lbs 1 lb 1.6 oz
Bio Release/Solu-PLKS 15 gal 10 gal 5 gal 2.5 gal 0.5 gal 6.4 oz

Note: If you have built your own brewer, please make sure the air supply lines are above the full level of the water in the tank. This will prevent back-flow of the water into your air pump if you turn off the air supply while there is still water in the tank.

You can download our "Build Your Own Brewer" document here for instructions and equipment needed to build your own brewers.

You can also watch a video demonstration of how to brew microbial mineral tea.

 

1500/1000 gallon brewers

Note: If you use chlorinated water, you must fill and aerate the tank for 15-20 minutes before adding any brewing ingredients in order to dissipate the chlorine.

  1. Use 4 30” x 30” brew bags
  2. Divide the Bio Phos between two of the bags, spread flat in the basket (can be used for three batches of tea)
    Be sure the bags lay flat and the material is spread out evenly inside in order to maximize air and water flow through the material. This will better dissolve the minerals and move the biology from the material into the tea.
  3. Divide the Pretreated Humus between two of the bags, spread flat in the basket (can be used for one batch of tea)
  4. Fill brewer with enough water to completely cover the brew bags – preferred water temperature is 65-72 degrees F
  5. Turn on the air – dissolved oxygen should remain above 6 ppm at all times during the brewing process
  6. Pour the Bio Release over the brew bags
  7. Brew the tea for 24 hours and then remove the bags and clean them as indicated in the “Cleaning the tea bags” section below
    (If you don’t remove the bag, it can easily turn anaerobic and sour at which point the contents must be thrown away)
  8. Keep the air flowing in the brew tank until all the tea is dispensed

The Microbial mineral tea will last for up to 30 days as long as you keep the air flowing. These are aerobic organisms and require air to live. Once you turn the air off, you have 6-8 hours to apply the tea to the plants or soil, for best results.

When you need to change the contents of a brew bag, you can spread any remaining material on your garden or field. After you have emptied the bag, it must be washed out thoroughly before reusing. If you are not planning to use it right away, spread it flat to dry and then store it out of the sun.

500/250/50 gallon brewers

Note: If you use chlorinated water, you must fill and aerate the tank for 15-20 minutes before adding any brewing ingredients in order to dissipate the chlorine.

  1. Use 2 9” x 30” brew bags (for 50 gallon, use two 8” x 8” bags)
  2. Place the Bio Phos in one bag and spread it flat in the basket (can be used for three batches of tea) – with both bags in the basket, you may have to turn them slightly on their side to fit. Try not to set them on top of each other.
    Be sure the bags lay flat and the material is spread out evenly inside in order to maximize air and water flow through the material. This will better dissolve the minerals and move the biology from the material into the tea.
  3. Place the Pretreated Humus in the other bag and spread it flat in the basket, next to the other bag (can be used for one batch of tea) – with both bags in the basket, you may have to turn them slightly on their side to fit. Try not to set them on top of each other.
  4. Fill brewer with enough water to completely cover the brew bags – preferred water temperature is 65-72 degrees F
  5. Turn on the air (it is best to turn on the air when the water is only a few inches above the aerating tubes) – dissolved oxygen should remain above 6 ppm at all times during the brewing process
  6. Pour the Bio Release and Fish Hydrolosate (if used) over the brew bags
  7. Add the Kelp Powder to the brewer once the water level is full (if used)
  8. Brew the tea for 24 hours and then remove the bags and clean them as indicated in the “Cleaning the tea bags” section below
    (If you don’t remove the bags, they can easily turn anaerobic and sour at which point the contents must be thrown away)
  9. Keep the air flowing in the brew tank until all the tea is dispensed

The Microbial mineral tea will last for up to 30 days as long as you keep the air flowing. These are aerobic organisms and require air to live. Once you turn the air off, you have 6-8 hours to apply the tea to the plants or soil, for best results.

When you need to change the contents of a brew bag, you can spread the remaining content on your garden or field. After you have emptied the bag, it must be washed out thoroughly before reusing. If you are not planning to use it right away, spread it flat to dry and then store it out of the sun.

Application

When applying the tea to your fields, apply at the rate of 15 gallons/acre (or as otherwise directed in your crop nutrient planning). It can be sprayed directly or injected into the watering system. Once you put the tea into your spray tanks, it must be applied within eight hours. After eight hours, the microbes use up their oxygen supplies and start to die off.

We absolutely recommend using a pre-filter when pumping the tea from the brewer to your spray tanks. This will remove any larger particles that may be suspended and prevent obstructions from forming in your sprayer filters or nozzles.

If you brew the tea for extended times (36-48 hours or more), the microbes will begin to form gelatinous colonies that can cause problems for spray nozzles but are generally not a problem for injection into pivots. If you are planning on spraying the tea onto your fields, use larger nozzles and be sure to spray quickly after the 24 hour brewing period.

Cleaning the tanks

The brew tanks should be cleaned out after each use to remove excess materials that may have settled to the bottom. The biology that is growing in the tea can also produce a bio-film that can coat the sides of the tank. These bio-films can build up over time and can become anaerobic and begin to breed pathogens. To prevent this, a good practice is to wash the tank with a mild detergent between brews to remove the bio-film layers. Rinse well to remove any detergent residue before the next brew.

Cleaning the tea bags

Each time you finish a brew, the remaining humus should be removed, dried, and then it can be spread on your gardens or flower beds. The bag should be immediately rinsed to clear any build-up in the mesh and keep it clean for the next brew. Spray out all the mesh openings in the bag fabric thoroughly so water and air can more easily pass through on the next brewing cycle. If you are not starting another brew immediately, Spread the bag out to dry and then store it in a protected location out of the sun (to prevent sun-rot).

The Bio Phos can be used for three brews. If you are not going to immediately start another brew, empty the material from the bag and spread it out to dry. Spray the bag thoroughly to remove any debris from the mesh and spread it to dry. If you are going to immediately start another brew, rinse the bag just enough to clear any sediment that has filled the mesh (rinse it over the brew tank) and then spread it out again. After the third brew, follow the same cleaning procedure as the humus bag.
