Abstract: In recent years, a major development strategy and policy of Taiwan`s agriculture is to transform traditional farming to environmentally friendly farming and organic farming. Tea leaves is an essential cash crops in Taiwan, meanwhile, tea drinking habits has increased significantly among people. The recognition and preference of organic agricultural products has therefore led to gradually increased in organic tea farms. Similar to any other organic products, tea leaves will have to be certified the organic certification with an appropriate growing and handling process to be sold as organic tea. The organic certification process is complicated and requires plenty of documents to be reviewed. However, majority of population that engaged in agricultural farming are
middle-aged and older farmers, the electronicalized process and information caused considerable difficulties. Further, the organic certification is not certainly trusted by the public. To resolve the challenges faced by organic agriculture production and marketing, this research will investigates organic tea farms in Highland Experimental Farm of National Taiwan University and nongovernmental organic farm, adopts experiences from current industry’s production process, and design a RFID (Radio Frequency Identification) sensor device which integrates bar code scanner and wearable barcode scanner. In addition, an automatic programming process and registration system will be established. On-site staffs can easily follow the procedure to scan the bar code or sensor the RFID tag on the materials, the sensor device will recognize the information and send it to registration system through smartphone, the process of traceability system for agricultural products becomes more efficient, and reduces the difficulties and complexity. In the meantime, the optimization for organic tea certification will be developed based on Taiwan Good Agricultural Practice (TGAP) and practical demands of industry. Software used to scan the bar codes or RFID tags are expected to reduce the time and manpower in processing the registration and trace for agricultural products. This IoT system based automatic agricultural production management enhances the completeness of production and management data, increases the convenience and credibility
of inputted information, which strengthen the traceability of the products. The blockchain technology ensures the transparency ofinformation and prevents the information from alteration. The
establishment of crop traceability system provides detailed, complete and verified growth information. Analysis and evaluation will be done to discuss if the information retrieved through integration of IoT and blockchain technology can be adopted in organic certification, as well as reduce the certification process difficulties. Qualitative research including interviews with tea
farmers and marketing unit will be taken place to learn the current organic tea farming challenges and sales issues, and identify the present demands and dilemma in organic tea production and marketing. Blockchain system will be promoted through education and training session, which
demonstrates the convenience of registering and uploading information to the cloud along with production and handling process, as well as evidence the efficiency of encrypting the information.
Nitrogen fertilizer is widely used during the organic tea farming; however the efficiency of nitrogen in organic fertilizers is weakened, which results in a larger amount of usage. Other appliance in pest control and the certification process also increase the prime cost, therefore the organic tea often become high-priced products, but public still often question the quality. It is necessary to identify the corelation between organic materials usage during organic farming and the actual product quality. Nutrients efficiency may also be affects by environment temperature, soil moisture, breeds and many other factors. It is important to further investigate and analyze the relationship between organic materials varieties and organic tea quality, and thus develop a
recommendation for farmers as reference.
