Abstract
Agriculture is a system of food production that remains important source of food in every country in the world. In the Philippines, corn is one of the
two most produced crops grown by Filipino farmers. For a farmer to plant corn, it is important to analyse the soil nutrients. The three main
nutrients are Nitrogen (N), Phosphorus (P), and Potassium (K). Since, corn required high availability of Nitrogen (N), phosphorus (P), and Potassium
(K) to create high quality output. Farmers must ensure proper soil nutrients before planting corns. Currently, to check soil nutrients, soil samples
were sent to Department of Agriculture for laboratory analysis. Another option is the use of commercially available soil test kits. In this study, the
researchers developed a device, “N-P-K-lyzer” to identify the presence of Nitrogen (N), Phosphorus (P), and Potassium (K) using Optical Transducer.
The optical transducer as a wavelength detection sensor, which consists of three LEDs as light source, and a photodiode sensor as the light detector.
Testing soil samples shows that N-P-K-lyzer was able to read the same remarks as the readings from the Department of Agriculture Soil Laboratory.
The remarks are LOW in Nitrogen, LOW in Phosphorous and LOW in Potassium respectively. A mobile application developed in this study allows the
user to retrieve and view the stored readings.

Key words: Optical Transducer; NodeMCU; Soil Nutrients Identification; Mobile Application; NPKlyzer
