How to Make Organic Fertilizer

Posted by Manny on August 31st, 2008

Bioorganic Fertilizer (BOF) From Coir Dust And Animal Manures

Organic FertilizersBioorganic Fertilizer (BOF) is a processed inoculated compost from any organic material that has undergone rapid decomposition by the introduction of homogeneous microbial inoculants. This is different from fresh organic fertilizer where natural decay process is brought about by the action of heterogeneous microbes present in the organic matter. Compared with the traditional composting method, microbial inoculation hastens the decomposition from three months to just 3-4 weeks.
Inoculants are commercially available in selected areas in the country but could be easily accessed. Trichoderma harzianum , a single celled fungus hastens the decomposition of organic materials especially those high in lignin and cellulose like rice straw, coir dust, bagasse and weeds. Commercial inoculants i.e Greenmix, Mabijon composter are enriched with other beneficial microbes like the nitrogen fixing bacteria, Azotobacter.

Can I make organic fertilizer? To produce quality organic fertilizer, plant residues like coir dust, bagasse, mudpress, rice straw etc. must be mixed with animal residues. Leguminous plants could be part of the substrate to substitute part of the manure.


I. Raw materials: The amount depends on the desired quantity of heap and ratio of plant residue and animal manures which could be 1:1, 2:1 or 1:2. For a 4 ton heap at 1:1 ratio you need:
a) Coir dust (2T)
b) Chicken manure (1T)
c) Swine manure (1T)
d) Inoculant (1% of weight of raw material-40kg)

II. Small tools and implement
a) rakes
b) shovel
c) spading fork
d) sprinklers or water hose
e) plastic laminated sack as cover
f) wheelbarrow
g) Weighing scale
h) Siever (wire mesh size of ¼ of an inch)
i) Protective wear: gloves, mask, hat, boots

How to Make Organic Fertilizer

I. Site selection:
The ideal composting site is shaded and well drained and near a source of water. However, open areacould be used. Four tons of agricultural waste can be composted in a space measuring 4m x 6m.

II. Preparation of raw materials: Collect the required amount of coir dust, chicken manure and swine manure. Discard stones, plastics,metals and other non-biodegradable materials. Note their moisture content and weights. Divide coir dust into three parts.

III. Piling of materials

Step 1. Spread 1/3 of coir dust as the first layer.Water to about 60%moisture content.Press the sample inyour palm and when the water does not fall freely, then it is almost within the right water content. Apply the required amount of inoculant on top (0.5% of the weight of the material in a layer.)

Step 2. Spread evenly the chicken manure on top, water and inoculate.

Step 3. Repeat steps 1 and 2 but use swine manure instead of chicken manure. Apply the inoculant on top of the fourth layer combining the weight of materials in the fourth and fifth layers.

Step 4. As the topmost layer, spread evenly coir dust but do not inoculate. This serves as a buffer for odor.

Step 5. Cover the heap with laminated plastic sack to conserve moisture and prevent rainwater fromgetting into the pile.Incubate for 4-7 days.

IV. Mixing and turning over

Step 6. After 4-7 days, turn and mix thoroughly the materials. Water if needed during turning.Return the cover.Repeat step 6 at weekly interval.

V. Harvesting, sieving and further processing

Step 7. After three or four weeks, harvest the material. Ripe compost has dark brown toblack color, nooffensive smell,temperature is ambient and with 35% moisture content or lower. Screen the organic fertilizerthrough manual siever or mechanical sifter.

Step 8. Inoculate the sifted material with 0.5% of the inoculant, store for three days under shade.

Step 9. Put BOF in 50 kg plastic lined sack and seal. Do not pile directly on concrete flooring butprovide wooden platform and stack not more than10 sacks high. Store not more than 6 months in anaerated but dry area.

QUALITY CONTROL MEASURES: For a good quality bioorganic fertilizer,observe these points:

1) Separate the dry materials from wet ones.

2) Monitor periodically the temperature of the heap. It must be within the right temperature range. The heapmust heat up over 400C 24hours after heaping. Within the first week, desired temperature is 40-500C. Ifthis temperature is not reached, check wetness ofthe materials. Remove the cover, turn over the heap to allow excess moisture to escape. Temperature must reached up to 620C.

3) For a product to be registered with the FPA as pure organic fertilizer, it must have 5-7% total NPK with at least 1.5% N and at least 10% carbon. The organic matter must be 10% and above with a neutral to slightly alkaline pH.


1. increases yield and improves quality of crops

2. improves soil structure: better soil aeration,increases water-holding capacity

3. improves chemical properties of soil: corrects acidity, restores soil fertility by enriching soil with trace and other micro nutrients and organic matter

4. restores microbial balance and enriches soil with microfauna


The rate of application depends on the kind of crop to be fertilized. BOF application ranges from10-20 bags /ha or 2-6 kg/tree for bearing plantation crop like coconut. Initially, this recommendation must be combined with 50% of the recommended rate of inorganic fertilizers.


1. Reduced dependence on inorganic fertilizers
2. Renewable and locally available raw materials
3. Contribute to proper waste disposal
4. Generate employment opportunity
5. Contribute to biodiversity
6. Lessen environmental pollution

_ 4 tons of raw materials

    how to prepare a fertilizer from chicken manure

  18. Anna Lyn Hernandez says:

    ahm.. panuh poh mapapadali ang process ng pagawa ng organic fertilizer na gamit lang eh chicken manure

  19. Manuel says:

    @Anna Lyn Hernandez
    I’ll try to research about that topic and post it on this blog.

  20. Carmelo D Verdan says:

    In order to make good quality organic fertilizer you should add bacteria (microbes)to it. just follow the procedure . I use a soil conditioner/inoculant because it have many microbes, rhizo, mycorhiza, azobacteria etc. Just email me about this topic including fertilization protocol of different plants and trees. I use no pesticides in my farm…

  21. Angelica Musni says:

    ..malaking 2long po ung article nyo para po sa research project nmin..ask ko lng po sana if we can use the same procedures in making organic fertilizer from dried mahogany leaves??? pakalat-kalat lang po kasi sa school namin ung mga mahogany leaves..I’ll wait for your reply po..tnx po=)

  22. Manuel says:

    @Angelica Musni
    Siguro naman pwede kasi organic material din yun at wala namang problema kahit anong dahon ang gamitin mo. Unlike if you are using it as hebal medicine, syempre dapat yung tamang herbal plants ang kailangan. I have another post making chicken manure compost here:

  23. Carmelo D Verdan says:

    Ana Lyn and Angelica email me at you”re respective email address so I send the request…

  24. Carmelo D Verdan says:

    All kinds of leaves, coco coir and dust and other decomposable material can be make to compost then to humus as time goes. but this can be done thru use of microbes (soil conditioner/inoculant). Use just drench or spray it to file…. in less than a month you have a BOF/compost. But this is one aspect of plant nutrition in order for plant to grow healthy and pesticide free. Chicken and hog manure can be spray by the microbes.

  25. angelica musni says:

    thank you po.. pwede po bang gmiting substitute sa inoculants ung mga fungi na present on trees??as much as possible po kasi eh ayaw naming gumastos ng malaki kasi po ung school nmin ung mgpoprovide ng expenses for the project..kaya po kung pwedeng maghanap ng substitute eh un nlang po ung gagamitin nmin..

  26. Carmelo D Verdan says:

    Based on your observation or experiment..what fungi are present on trees…

  32. ahmad says:

    Could you please advise me where i can buy bok choy seed from philiphine.and also i need the to know the supplier to produce huge quantity chicken manure and goat

  33. Musa says:

    Dear Carmelo,

    I am very much interested in making organic manure for sale.

    I read your article on a certain website and even got more enthusiastic about the whole idea based on the fact that my country relies very much less on inorganic fertilizers.

    The primary raw materials available in the area I intend to do this is organic wastes especially plant products disposed of as garbage from the city markets. I have also started doing poultry production though still on a small scale and believe this could be of use too.

    How should I go about it?

    Kind regards,

  34. lorena says:

    uhm…just like others who posted their questions here..i also want to ask something about investigatory projects about making fertilizers…
    do you any suggested websites were i can get research articles w/c i can use for my rrl?…thats all..tnx..:D

  35. Carmelo D Verdan says:

    Lorena, there are many websites you can find in the internet… Making your own fertilizer will be a tedious one you have to considered many aspects,, because right now in agriculture not only the NPK fertilizer is use you also the micronutrient which must be chelated.. The one I am using right now Growmore products because it is complete plant nutrition per se.. you can contact me thru my landline (02) 5292137 and email address: our group also conduct seminars to farmers,land owners, students etc..

  36. Liza Villora says:

    Hi Sir!
