Recipe for making your own Bio-Fertilizer

Here we will be sharing with you the best formula for natural, nutritious fertilizer that we can make ourselves. This will not only reduce our community’s waste but also help us to make exceptional fertilizer for our gardens. We have come up with a few ways to make biofertilizers which is an effective, non-polluting, and nontoxic organic fertilizer. The biofertilizer helps in improve germination rates, resistance, and yield of production crops. Additionally, biofertilizer improves the soil texture and moisture retention of soils. Below, find a simple method for making your own biofertilizer at home.

Starch Water Biofertilizer

Fermented Starch Water + Milk + Time = Lactic Acid Bacteria (LAB)

Rice and potatoes may not be the first foods you would think of for making effective fertilizer, but the water you use to wash and cook them works extremely well. This is because it can create lactic acid bacteria, which significantly improves soil health by decomposing any organic matter and reducing any chance of unwanted pathogens associated with decaying material. It will also remove foul odors associated with composting and manure. This starchy water will allow the growth of indigenous bacteria. Milk will be used to isolate the desired bacteria needed for the best fertilizer possible while the unwanted bacteria will die off.

Required Materials:

  1. Personal protective equipment

  2. Glass jars with lids

  3. Rice or potatoes

  4. Water

  5. Milk

  6. Isopropyl alcohol

  7. Vinegar

  8. Cotton clothes/pillowcases


  1. Clean and sterilize every glass jar thoroughly with isopropyl alcohol or vinegar.

  2. Rinse rice in water for 5 minutes or boil potatoes. Fill a glass jar 2/3 with water from either starch and cover with a cotton cloth and elastic band. The cotton cloth allows for air exchange. Place the jar outside under a box. The box stops UV sunlight rays from killing the bacteria growing in the water. Let sit for two days.

  3. Take fermented rice or potato wash water and fill 1/10 of the new glass jar. Fill the remaining 9/10 of the glass jar with milk. Cover with a cotton cloth to allow for air exchange. Place on a shelf with no direct sunlight. Let sit for 5-7 days.

  4. Separate liquid from curds. This liquid is called Lactobacillus. Store LAB serum in glass jars with lids tightened. LAB has a 6-month shelf life.

  5. Dilute 1 tablespoon LAB serum with 1 gallon of water and apply to soil/compost and plants generously. Apply as needed.
