From the end of February 2025, Long An province predicted that during the 2024-2025 dry season, approximately 23,669 hectares of crops throughout the province would be at risk of being affected by drought, water shortage, and saltwater intrusion. The affected areas mainly include winter-spring rice (18,260 hectares), lemons (2,268 hectares), vegetables (469 hectares), and some other crops.
High-risk areas are concentrated in Thu Thua district (7,348.5 ha), Thanh Hoa district (6,363 ha), and Tan Thanh district (6,182 ha). In addition, some cultivated areas in Ben Luc, Can Duoc, Tan Tru districts and Tan An city are also included in the forecast.
To proactively respond to drought and salinity affecting crops and agricultural production, the Standing Committee member of the Provincial Party Committee and Vice Chairman of the Provincial People's Committee, Nguyen Minh Lam, directed relevant departments and localities to focus on monitoring water quality, measuring salinity levels in major rivers and canals, and promptly warning people to proactively store water; at the same time, they were instructed to inspect dikes and sluice gates to prevent saltwater intrusion, implement dredging of canals and ditches, and build temporary dams in key areas.
The provincial Department of Agriculture advises people to change crop structures in areas with insufficient irrigation water, apply water-saving irrigation solutions such as drip irrigation, sprinkler irrigation combined with nutrient supply through the irrigation system, and use organic fertilizers and micronutrient preparations to increase drought and salinity resistance. Adjust water supply accordingly when water resources are scarce to ensure efficiency in production.
For the 2024-2025 Winter-Spring rice crop already sown, continue to care for and monitor the water situation (pay attention to the fact that rice plants in the heading stage need freshwater for irrigation). For areas with insufficient irrigation water and potential for drought and saltwater intrusion, farmers are advised not to sow rice, but to switch to short-term crops, crops that require less irrigation water, and apply advanced, water-saving irrigation solutions to ensure sufficient water supply for crops.
For orchards, farmers need to increase the application of organic fertilizers, potassium sulfate, phosphorus, lime powder, etc., to limit toxicity caused by drought and salinity. During prolonged droughts and salinity, supplement with foliar fertilizers and preparations containing potassium, calcium, magnesium, and silicon to help plants increase their tolerance to drought and salinity. Avoid fertilizers containing sodium and chlorine, as these will increase toxicity to the plants.
For areas with orchards that are flowering and bearing fruit but lack sufficient irrigation water, pruning and shaping the canopy, thinning out buds, flowers, and young fruits can be beneficial. Simultaneously, mulching the base of the trees with dry leaves, straw, dry grass, and other agricultural by-products can help retain soil moisture, reduce water loss, and prevent tree weakening. Planting new fruit trees in water-scarce conditions is also discouraged to avoid losses.
Long An province is urging residents to closely monitor weather reports, proactively take preventive measures, and cooperate with authorities to effectively respond to drought and salinity intrusion. They should also conserve water and adapt their crop structure accordingly, ensuring stable production and livelihoods during this year's dry season.
