Abstract:
As the population grows in Sri Lanka, the demand for food and agricultural crops grow as well.
Thus, the new tendency in farming techniques which include new fertilizing techniques has
evolved., coconut water is rich in many macro and micronutrient such as potassium, and
phosphorus which is essential in plant growth. Hence, this research is aimed at formulating a
fertilizer by utilizing waste coconut water as an organic constituent and the nutrient analysis,
physio-chemical and microbiological analysis were done for the formulated fertilizer to analyze
its capability as a fertilizer.
chemical fertilizer importation has been banned in Sri Lanka due to many economic,
environmental, and health reasons. Therefore, Sri Lankan agricultural sector is now facing a
shortage of fertilizers. Thus, Sri Lanka is focusing on developing healthier, eco-friendly, and
economically beneficial alternatives for replacing chemical fertilizers. On the other hand, the
coconut industry is one of the major industries in Sri Lanka and coconut water is wasted in
coconut industries without utilizing them.
Silvermill Natural Beverages (PVT) Ltd, in Loluwagoda, is a number one coconut-based
beverages producer and exporter in Sri Lanka which is discard about 100-200L of coconut
water as waste daily Moreover, the formulated fertilizer was tested on plants to analyze the
effect of the fertilizer on plants. The formulated fertilizer was compared with a market
available foliar fertilizer. The findings of the research indicated that the formulated fertilizer
with coconut water is a good alternative for commercial fertilizer and more suitable for
phosphorus intake rather than nitrogen intake of the plants.
