When you learn how to make organic liquid fertilizer, you discover a goldmine for your garden.

One of the best ways to continuously feed nutrients to your plants is to use an organic compost. But compost takes some time to make, and sometimes you can’t or don’t want to make it or buy it. So if you’re in this circumstance, luckily you can attain the next best thing to organic compost… organic liquid fertilizer!

How To Make Organic Liquid Fertilizer

Here’s a good video on making KNF fertilizer I found on YouTube:

The overall process of making all fermented bio liquids is this:

  • Take plants, herbs, fruits, or animal meats
  • And ferment them with water, sugar and time.

That’s it.

Organic liquid fertilizer is also referred to as “fermented bio liquid.”

Making organic liquid fertilizers is not hard. And if you’ve ever brewed your own beer, then you’re already an expert.

It takes some fine tuning, like finding the proper waiting area, storage container and ingredient/water amounts, but that’s as hard as it gets.

The hardest part is finding where to put the container. I like to use garlic for my herb hormones. Its powerful smell lingers wherever you have it, so I leave it far from the house in a shaded area.

Make sure any organic liquid fertilizer you make gets ZERO direct sunshine. Indirect sunshine is also best avoided.

Mold will often grow on the top.

If it’s black mold, you must throw out your batch.

My mother in law saves the white mold that grows and says it’s not mold. If that’s the case then it must work as some type of scoby or something, but I am not sure about this. I don’t save that white part. If you see white mold growing, this is a good sign, don’t worry about it. However, I don’t want anything with mold growing in my house. There’s enough mold spores in the air as it is, so I don’t leave these biofertilizer containers in my house or garage to ferment.

Applying Organic Liquid Fertilizer Combinations

Combinations are KEY to using these liquid fertilizers on natural farms.

I’m having a hard time putting this into words, so I’ll just share an example of what I mean by saying “combinations are key”.

After placing seeds in the dirt where I’m growing red leaf lettuce, for example, I am using a 1:1 part fermented brown rice water and liquid herb hormone. This is then diluted with water.

Ideally, FPJ would also be in this combo.

The way I learned this is to combine all 3, the brown rice water, the LHH, and the FPJ. You combine all these evenly and then dilute them according to the application.

So it would be 1:1:1 part fermented brown rice water, liquid herb hormone, and fermented plant juice.

For soaking seeds, dilute heavily so the mixture is not too concentrated.

For seedlings, dilute with a lot of water as well, like 1:500. Once the plant is full grown and producing, you can make it stronger, like 1:100 or 1:50 (3-part ferment combo and water).

In order to get maximum effectiveness from your liquid fermented fertilizer, you should make several types and then evenly mix them/dilute them for use on your natural farm.

Diluting Liquid Fertilizer

Using the wrong concentrations is the biggest mistake you can do when natural farming with fermented bio liquids.

Undiluted, it’s too strong for direct application on the plants.

Even the soil should use a diluted liquid fertilizer.

This extends the usage of your batch, and is all you need to nourish your gardening soil.

The main one we use is a mixture of the brown rice water and the liquid herb hormone. FPJ should be in this combo, but the 2 alone have worked well as well.

Storage And Fermenting Containers

We use a clay pot most the time, but the glass pots I’ve made them with were always successful as well. Clay pot with a cloth on top tied off is the best way. This means there is some oxygen inside, but we try to get most of it out before capping it off.

Suggested pH Levels

The pH level of most fermented bio liquids is acidic. It’s usually around 4. The acid comes from the fermentation, as microorganisms produce lactic acid among other end products.

A pH level of 3.0 to 4.0 signals that your fermented bio liquid is ready.

If you make fermented bio liquid from snails, it will not be acidic because snail shells are calcium which is alkaline.

Benefits Of Using KNF Liquid Fertilizers

  • Prevent diseases in plants to avoid ruining your crops
  • Prevents bacterial attacks
  • Prevents insect invaders
  • Helps your plants produce more
  • Helps make your plants stronger (stems, leaves, roots)

What the fermentation does is it extracts the liquid from plants or animal cells (or whatever organic matter you’re using), and helps break down the material and eventually creates wonderful plant food nutrients like amino acids or humid acid for example.

Are there downsides of using these KNF organic liquid fertilizers? No.

Why KNF Liquid Fertilizers Work

BioFertilizers work from the process of breaking down all the organic materials into various plant nutrients.

Brown sugar is the key ingredient.

In nature, a type of fructose is released from the roots of plants. This is nature’s way of providing microorganism food.

This is why a type of sugar is necessary for your ferment fertilizer. Sugar is what causes the fermenting liquid’s osmotic pressure. It helps extract the liquid from your plant or animal ingredients used.

Is brown sugar mandatory in organic liquid fertilizer recipes?

Brown sugar is best because it has NOT been carbonated such as white cane sugar. What this does is it makes it much safer for the microorganisms and thus creates a proper BioFertilizer.

For large natural farms with tons of production, molasses is used because it’s more economical than brown sugar. Molasses is just as effective as brown sugar because it provides all the essential nutrients that the microorganisms need to go to work in breaking down the organic matters you chose for your ferment.

Various Types You Can Make At Home

You can make many different types and each will vary in quality and effectiveness depending on what you used to make them. You can use the following ingredients to make various forms of liquid fertilizers:

  • green leafy plants
  • aquatic plants (seaweed)
  • food scraps (organic)
  • fruits
  • medicinal herbs
  • animals (fish, meat scraps, etc.)
  • human waste

And of these main categories of fertilizer ingredients above, there are endless types of ingredients you can use and each will create a different result.

For example, I could have used any number of medicinal herbs for my current liquid herb hormone batch, but I chose one of the best combos; garlic and ginger. I learned this homemade liquid fertilizer bio liquid combination from my mother in law who’s got a lifetime of Thai farming wisdom.

Can organic liquid fertilizer replace composting?

However, what if for whatever reason you can’t get enough organic compost fertilizer for your garden? An organic liquid fertilizer (also known as a fermented bio liquid) can be used in place of compost.

Organic liquid fertilizers offer an effective way to successfully grow a no till organic garden without regular use of quality compost. They’re not a complete replacement, but for small time gardening they can be.

The downside to not making your own organic liquid fertilizer is its price. It will add up in cost quickly. Fermented bio liquid fertilizers are full of natural microorganisms that help nourish your plants.

That’s why learning how to make organic fertilizer is the ultimate skill if you run a natural farm. If you make compost, you can make fermented liquid fertilizers. Also, they’re most effective when made with local plants from your area.

We have a post here on the blog that shows how to start your own compost pile.

2 Fermented Bio Liquid Recipes

  1. Organic Fermented Brown Rice Water
  2. Liquid Herb Hormone (OHN)

These are the first two liquid ferments I learned how to make. As I make more, I will publish additional posts with their recipes and usages. For example, I’m currently making a fermented plant juice (FPJ). FPJ can be made from so many different types of plants it’s crazy. That’s the beautiful thing about natural fertilizer liquids. You can literally make it from weeds you have growing between your driveway cracks. For most effectiveness, however, FPJ would be better off made from organic, leafy greens such as red leaf lettuce, arugula or kale.

Recipe #1. Fermented Brown Rice Water

fermented brown rice water

Fermented brown rice water only takes around a week to complete.

Ingredients Needed:

  • Brown Rice
  • Milk
  • Water

How To Make:

Step 1. Rice and Water

  • Just like when cooking rice for eating, use 2 parts to 1 of water and rice.

Step 2. Soak

  • Soak the rice for 3 to 5 days without covering.

Don’t wash the rice. Take the rice and put it directly into the water. Then put it away in an area without sunlight that is not too cold or else it won’t ferment or will ferment very slowly and might not be as effective. Use a clay container or a glass container. Plastic is best not to use for the fermented bio liquids.

Step 3. Throw Out The Rice

  • Next, strain off the rice and keep the water (throw out the rice.. chickens love it). This is what you will be using.

Step 4. Add Milk

  • Next, add milk at a 1:10 ratio. So for 10L of rice water, use 1L milk. Then, cover the container with a thin breathable sheet.
  • You can use pasteurized milk, it provides enough lactic acid helps the targeted bacterias to grow.
  • Store away the brown rice water with the milk for another 7 days, then the ferment will be complete.

Step 5. Storage

  • It will stay good for up to 1 year if you store it in an airtight container.

The last time I made fermented brown rice water I used my wife’s breast milk for the milk part (we had some in the fridge that was past the date for giving it to our baby. Normally I’d give it to the puppies or dogs, but this milk went to the brown rice water and worked perfectly.

How To Use Brown Rice Water

Use it to soak seeds for an hour before planting.

Use it alongside Liquid Herb Hormone in a 1:1 ratio.

Use it with Liquid Herb Hormone & Fermented Plant Juice in a 1:1:1 ratio PLUS water (up to 500 to 1,000 times)

It can be used to prep the soil before planting, for cleaning the seeds (soaking), for ensuring budding flowers and sprouts grow stronger and faster, as a natural insecticide, and as a weekly treatment to help support healthy plant growth overall.

Dilution Guide

Dilute 500 times for seedlings

Dilute 500 times for seed soaking

Dilute 200 times (and mix with fermented liquid calcium 1 part to 1,000) then spray on nightshades to prevent and cure bacterial disease.

Recipe #2. Liquid Herb Hormone (aka Orient Herbal Nutrient or OHN)

For this last batch we used garlic and ginger. You can use any combination of medicinal herbs though.

Ingredients Needed:

  • Garlic
  • Ginger
  • Alcohol: the extractor does not need to be alcohol. You can use straight water (takes longer) or wood vinegar too.
  • Sugar
  • Water

How To Make It:

Step 1. Prepare Medicinal Herbs

  • Chop up the medicinal herbs, then smash it in a mortar and pestle.
  • After smashing the herbs, put them in your ceramic pot and fill it 1/3 full with the smashed medicinal herbs.

Step 2. Top Off With Extractor

  • Top the smashed herbs off with any form of alcohol (beer, moonshine, rice whiskey, tequila, etc.)
make liquid fertilizer at home
  • After you do this, let it sit for a few days UNCOVERED.

Step 3. Add Sugar

  • After the initial 3-day waiting period, fill up the ceramic up with water to make the whole contents amount filled up to 2/3.
  • Mix well so that the sugar dissolves
  • Cover with a breathable cloth or paper and tie it tight with a rubber band or string to prevent the fruit flies.

Step 4. Storage

  • Keep it in an airtight container.

That’s it!

It should not smell sweet.

It should not smell sour.

It should smell nice, in a way. It will be strong, but it won’t smell soured and bad.

If you see white mold growing that’s fine. If you see black mold growing, throw it out. Something happened that ruined the batch.

How To Use LHH:

Dilute it with water times 500 to 1,000.

Mix it in a spray bottle and spritz your plants every week or a few times per month to keep them strong and help them fight off potential diseases and invader insects.

More bio liquid fertilizers you can make:

  • Fermented Fruit Juice (FFJ)
  • Fermented Liquid Animal Protein
  • Fermented Liquid Lactic Acid
  • Fermented Liquid Calcium (Water Soluble Calcium)
  • Fermented Liquid Calcium Phosphate
  • Fermented Liquid Potassium
  • Fermented Liquid Magnesium
  • Fermented Liquid Boron
  • Liquid Natural Minerals (Bacterial Mineral Water or BMW)
  • Liquid Compost From Human Waste
  • Liquid Herb Hormone

My current ferment in process is this FPJ.

Update: Here’s the Fermented Plant Juice (FPJ) recipe.

In time I will have made each organic liquid fertilizer above and hope to make a recipe blog post here on SproutingFam (once perfected). Until then, we have plenty of good information online to learn from! Chris Trump and another couple called Natural Farming Hawaii both share how to make a lot of these.

Natural farming in Thailand is derived from various methods learned from surrounding countries and decades of experience. Korean Natural Farming has a strong influence in natural farming in Thailand. Along with Korean farming methods are Japanese natural farming methods. I use methods learned here in Thailand. These can be used worldwide. Organic BioLiquids are necessary for natural farming in any region around the world, from the sunny California coast to the cold plains of the midwest.

An organic liquid fertilizer for your garden can also be one of the best lawn fertilizer options as well. Using an organic lawn fertilizer would be much better than a chemical one for you and your family, and your neighbors too.

Growing plants with organic liquid fertilizers is an effective and fun way to farm. Learning. How to make them is also a nice skill to have. You can literally make these natural liquid fertilizers for free. You can use scraps, plants around the house, or other herbs you grow in your garden to make this fermented bio liquid. The only things you really need outside of the plants, herbs or fruit are the sugar and water.

So, what do you think?

Have you made this liquid biofertilizer before?
