DQ Farm (est. 1991)

The disposal of carcasses and animal wastes often pollutes the environment.  In Malaysia, farms generally bury them or burn them. 

At DQ, we compost them and return them to the soil as fertiliser and as soil amendment.  We have innovated our own method of composting carcasses, after much trial and error,  as follows:

Lay the carcasses and wastes in layers and between the layers, cover them with carbon material such as dried lallang, leaves, etc.  We generally require the abdomen of all carcasses to be opened to prevent inadvertently creating anaerobic conditions from forming inside the carcasses which may result in the formation of toxins.

Lactobacillus is sprayed on the layers to speed up the heating process. Lactobacillus is a medium heat microbe and works well and fast at our ambient temperature of around 30 celcius. Within a day they will bring the temperature of the heap to 45 celcius for the thermophilics to take over.

Cover the carcasses carefully with dried brown (carbon) material.  If done properly there will not be any smell and there will not be any scavenger animal digging up the carcasses. 

With enough moisture and oxygen, actinomycetes will jump into action almost immediately breaking down the materials in the heap and giving the characterisitic "earth" smell to your compost at the end.

After the layers have been build up to a sufficient height, we cover the pile neatly with any old canvas.

Cover up the pile neatly to retain the heat for the thermophilics to do their work thoroughly.

After a couple of days, the heat generated will be sufficient to cook an egg in a short while.  Or to cook beef:

65 celcius - hot enough to cook beef.

The pile or heap should be turned a minimum of two times to ensure that as much of the material has gone through the heating process to destroy pathogens and even some toxins.  At DQ this process will take 30 days. 

After that, we introduce local composting earthworms to turn the compost to humus / vermicast.  The composting earthworms ( eisenia fetida) works pretty fast, within 10 days they will have a few inches of vermicast for you to collect and use.

( Do not use imported earthworms as there are millions of microbes in the guts of earthworms and you may be introducing 'aliens' to our environment).

Beautiful black humus in just 40 days.  The end result is a microbes-rich fertiliser suitable to be used as a soil fertiliser, as an amendment or as a foliar spray.  We use this humus to build up sandy soil, as an anti-fungal, as fertiliser and generally to return to the soil what has been taken from it. 

If you are already applying some other organic fertiliser, the addition of humus made the DQ way at a rate of 100kg per acre to acre and a half will see a 10 to 15 percent improvement in yields.  And that's 10 to 15% straight to the bottom line as the inputs used are generally free!
