FARMING ADVISORIES

AREAS AFFECTED BY THE WEATHER SYSTEMS
SHEAR LINE, NORTHEAST MONSOON, THUNDERSTORMS AND MODERATE TO HEAVY RAINS

  • Install temporary plastic tunnels or rain shelters for sensitive vegetables (tomato, pepper, leafy greens).
  • Strengthen staking and trellises for vine crops to prevent collapse due to strong winds and wet soil.
  • Apply mulch or organic matter to reduce soil splash, erosion, and weed growth around plants.
  • Dig shallow drainage canals or diversion ditches in low-lying areas to avoid water pooling.
  • Place sandbags or bamboo barriers around fields near rivers or creeks.
  • Apply foliar fertilizers (especially micronutrients) after continuous rains to support recovery.
  • Avoid heavy fertilizer application during rainfall to prevent nutrient leaching.
  • Harvest mature produce early before heavy rains if possible.
  • Use covered drying areas for grains, corn, coconut, and root crops to avoid spoilage.
  • Store seeds and produce in elevated and well-ventilated areas away from moisture.

Promote the use of raised beds, contour farming, and proper field levelling to prevent waterlogging and support better drainage during prolonged rainfall events. Strengthen bunds and levees around rice fields and low-lying farms to reduce the risk of overflow from nearby rivers and canals. Install windbreaks using bamboo, live trees, or netting to protect sensitive crops from strong winds. Harvest mature and near-mature crops ahead of forecasted heavy rains to minimize losses and ensure better post-harvest quality. Use portable dryers, plastic-covered drying floors, or elevated racks to protect harvested grains, root crops, and coconut from moisture exposure. Conduct regular inspections of storage facilities, ensuring all produce, seeds, and feeds are kept dry, elevated, and well-ventilated to prevent mold and spoilage. Implement schedule-based pest and disease scouting, particularly for fungal infections that commonly occur after continuous rains, and apply appropriate control measures immediately. Coordinate closely with the Municipal/City Agriculture Office for updates and emergency support related to agricultural impacts in your area.
