Kitchen waste composting

Puede ring gamitin ang timbang plastic o balde (can)

Trichoderma microbial inoculant (TMI) or compost fungus activator

Paglalagay ng paper lining kung ang gagamitin ay balde - can or plastic na timba

½ - 1 kutsarita TMI ang gamitin sa tuwing maglalagay ng bagong basura

Gawin ito kung tuyo ang basura; huwag sobrahan ang basa

1. Ang magandang kompost ay walang amoy. Kapag may masamang amoy,

kulang sa hangin at sobra ang tubig ang proseso ng pagbubulok. 2. Kung isasama ang mga laman loob ng isda o karne pakuluan muna ang mga ito bago ihalo. 3. Dapat ang kompost ay kulay lupa at hindi na nakikita ang bahagi ng orihinal na materyales na isinama. 4. Huwag gagamitin ang kompost kung mainit pa ito. Kung mainit pa hindi pa tapos ang pagbubulok. Makasasama ang mainit na kompost sa halaman.

Tandaan huwag sobrahan ang basa

Yard waste composting

Steps: Pictures courtesy of the project of Dr. F. C. Sanchez, Jr. 1. Choose an area that is not water logged.

2. Prepare an improvised platform to provide air passage using woody trashes.

3. Use large trash leaves as lining.

4. Pile loosely yard wastes.

5. Moisten the wastes especially when dry.

6. Apply TMI or activator – 250 -500 g/ton of wastes (0.025 to 0.05%)evenly over the wastes; more TMI are needed if wastes are woody.

7. Apply animal manure if available. Ideal ratio 20 – 30% animal manure to the total wt of the substrates. This step is optional.

8. Add more yard wastes.

9. Apply evenly again the TMI. 10. Moisten when the wastes are dry.

11. Add the manure again. Repeat the whole process until all wastes are utilized.

Sequence – yard wastes, moisten, activator, manure

12. Cover the pile with plastic. Cover will keep the heat generated by microbial respiration which are active in decay process. Cover will also keep the wastes moist.

13. Coconut/banana leaves can also be used as cover.

Compost after two months. The only recognizable original substrates were the fruit peelings - soft and can be easily crushed.

Hard and woody materials take longer time to fully decompose.
