Biological fertilizer
Biological fertilizer is an organic fertilizer that has gone
through a process of fermentation by adding biological

extracts to improve the soil and feed the plants.
Materials
1. Manure 3 Parts
2. Husks 1 Part
3. Other Organic Material 3 Parts

(husks or saw dust, you can choose one or use both together)
4. Fine Bran 1 Part
5. Biological Extract, Micro organism 1 Part

6. Molasses 1 Part
7. Water 100 Parts
8. Water Lotus
Note: The auantity of the materials used should be adjusted

. appropriately, the rice bran should be not less then 10%
because it is an important food needed for the micro organisms.

Day2 Steps/Methods 4 Hours
1. Place the various materials on top of each other in
layers and mix well together.
2. Make a mixture of bio extract with molasses and water.

Mix together until it is moist enough, so as not to dry quickly
but not too wet either (about 40-60%). Test the fertilizer by
squeezing it in by hand, if it stays in its form and does not
crumble it means the fertilizer is well done, but if it does

crumble some water needs to be added.
3. Ferment the fertilizer for 7 days, and then it can be used.
