The parameters of cultivation techniques inclduing soil pH, EC, the density of soil microorganisms, and dehydrogenase enzyme activity in the soil were collected. The results showed that most farmers had rich experience, varying from 10 to 70 years. Although most farmers (59.5%) have converted to organic coconut farming system from conventional one, a part of them still use chemical fertilizers and pesticides on their farms, causing ecological imbalance. The results also showed that applying organic fertilizer regularly to coconut farm soils helped to increase the dehydrogenase enzyme activity of soil microbes compared to the group of traditionally cultivated gardens.
