The case for coconut waste utilization, II

coconut water can be a good fertilizer

Forget nata de coco.  Or coconut vinegar.  Or coconut wine from coconut water.  Passé they all are in light of the food crisis obtaining in the Philippines.  To nip in the bud this penchant for importing foodstuffs, foremost of which is rice, the focus should be on organic fertilizers so as to triple up the country’s food production.

There are two types of organic fertilizer: the foliar or liquid and the powder or flake.  Utilizing coconut water for fertilization falls under the first category.

From copra production, the Philippines throws away 16 billion liters of coconut water per annum.  In and of itself, coconut water is a complete food for the coconut embryo.  The putrid smell from its decomposition is a testament that coconut water is full of nutrients, reminding you of the protein shake that you forgot to dispose of, which assaults your nostrils upon putrefaction.  Indeed, the foul smell of  a decomposing substance indicates that it is a good source of fertilizer after fermentation and ageing.

From the analysis above by Satyavati Krishnankutty (1987),  coconut water is rich in potassium–the “K” in N-P-K in commercial fertilizers.  At the same time, coconut water is not that rich in protein (< 1%), which upon decomposition, yields nitrogen.

So that to convert coconut water into liquid fertilizer, we need materials rich in nitrogen and phosphorus as adjuncts, disregarding those with potassium because coconut water has it already.

What then is the process?  First we have to gather the coconut water.  Then, we inoculate it with lactobacillus, 10% by volume.  We then add top layer bat guano (nitrogen rich) and middle layer bat guano (phosphorus rich), both of which should constitute 20% of the whole mixture.  Then we let the whole thing ferment anaerobically for 30 days.  We then heat up the liquid fertilizer to kill undesirable organisms.

To use the fertilizer, we add plain water and a little coconut oil or soapy water as surfactant, one part liquid fertilizer to one-and-a-half parts water.  Bingo, we now have the best liquid organic fertilizer which we can use for our rice plants, vegetables and fruit trees.

  1. This is a wonderful proposal to use the tender coconut water, which are most often discarded, as rich source of organic fertilizer. I’ll introduce this idea to my entrepreneur friends. Perhaps some of them will be bold enough to venture on this kind of agri-business.

    Indeed, there are now bigger ripples, which am sure will surge out into a tsunami, within our agricultural sector to adapt organic farming. One of these initiatives have produced a farm product which neutralizes soil acidity into an alkaline-rich 16.4 pH. The product, called MIRACLE SOIL CONDITIONER (MSC) is also a biodegradable insect repellent. May I refer you to this blog for more information on MSC.

    Anyhow, my warm congratulations to Benito Maray for coming up with this insightful article.

    1. Thank you, Jess! I hope our ripples will indeed become the tsunami you are talking about. Keep up the good work re your superb product, the Miracle Soil Conditioner. It is definitely A-1.

      All the best.

    Low in calories, naturally fat- and cholesterol free, more potassium than four bananas, and super hydrating – these are just a few of the many benefits ascribed to America’s latest health craze: coconut water.Dubbed “Mother Nature’s sports drink” by marketers, the demand is skyrocketing, propelled by celebrity and athlete endorsements and promises to hydrate the body and help with a whole host of conditions, from hangovers to cancer and kidney stones.`
