17. EVALUATION OF SOIL QUALITY AT PHU MY SPECIES - HABITAT PRESERVATION AREA, GIANG THANH DISTRICT, KIEN GIANG PROVINCE

Tóm tắt

The study aimed to assess soil quality in Phu My Species - Habitat Conservation over the period of 2019 - 2021. Soil quality data were collected at 10 locations in seven habitats in the nature reserve. Soil samples were evaluated by pH, electrical conductivity (EC), salinity (sal), total acidity (TA), soil organic matter (OM), total nitrogen (TN), total phosphorus (TP), available phosphorus (P₂O₅), digestible potassium (K₂O), aluminum ion (Al³⁺), and total iron (Fe_t). The results showed that the pH in the soil was low, the nutrient content was poor, while the aluminum ion and organic matter content in the soil were relatively high. In the period of 2019 - 2021, the pH, EC, Fe_t, and nutrients (TN, K₂O) tended to decrease, while the remaining parameters increased in 2021. The soil quality could limit the diversity of flora and fauna in the conservation area the except for the highly adaptable species. The results provided useful information on soil quality for soil planning management. Future studies should focus on the determination of frequency and location for soil quality monitoring at Phu My Species - Habitat conservation area.
