Abstract

The agriculture is the main source of foods and it plays an important role on economic growth. The chemical fertilizer that does not absorbed by the plant become the chemical waste in the soil and flow to the underground water and cause water pollution, soil pollution and acidic rain. The waste of fertilizer in agriculture activities should be minimize to prevent the degradation of the environment. Hence, this project describes the design and development of on-the go and real time measurement for soil fertility by using All Terrain Vehicle (ATV). Conventionally, the soil sample need to be sent to laboratory for lab analysis and take about 2-3 months. Therefore, the device that can measure and analyses the soil fertility on-the go to determine the fertilizer recommendation. The Ion selective electrode (ISE) for Nitrate (NO3-) and Potassium (K) micronutrient with the GPS device will be installed on the ATV mobile platform and can be easily changeable. The main objective of this paper is to design and develop a soil proximal sensory based soil collecting system with GPS that able to analyses the concentration of the micronutrient contain in the soil and form a fertility mapping. The percentage of error for the sensor will be evaluated before the starting the soil sampling. The soil sample will be done in palm oil field, the depth of the soil collected in 20 cm and 42 samples collected in distance of 10 m between each sample in area of 4 acres. The correlation of the proximal soil sensor and the lab analysis will be done. In the end, the soil mapping and the recommendation map to the farmer based on the result will be developed.
