PRODUCTION OF ORGANIC FERTILIZER FROM HERBAL MEDICINE WASTE AND AGRICULTURAL WASTE.

Abstract

     This research aimed to study the appropriate ratio of herbal waste and agricultural waste to produce organic fertilizer and to test the properties of organic fertilizer from herbal medicine waste and agricultural waste. This research was an experimental research using the study area at the herbal medicine factory, Khlong Si Subdistrict, Khlong Luang District, Pathum Thani Province and the Soil Chemistry and Fertility Laboratory, Department of Soil Science, Faculty of Agriculture, Kamphaeng Saen, Kasetsart University, Nakhon Pathom Province. The research methodology was divided into 3 phases: Phase 1: Raw material preparation, Phase 2: Organic fertilizer production, and Phase 3: Testing the properties of organic fertilizer. Data were analyzed using content analysis, frequency, percentage, mean, and standard deviation.

     The results of the research found that organic fertilizer from herbal medicine waste and agricultural waste was in the form of powder and dark brown colour with a pH of 8.92 and an electrical conductivity of 1.08 decisiemens per meter. The organic matter content is 38.47 percent, the carbon to nitrogen ratio is 16:1, the total nitrogen is 1.42 percent, the total phosphorus is 1.54 percent, and the total potash is 0.74 percent, respectively, which are classified as high-quality organic fertilizers as specified by the Land Development Department.
