FARMING ADVISORIES

AREAS AFFECTED BY THE WEATHER SYSTEMS
LOW PRESSURE AREA, NORTHEAST MONSOON, SHEARLINE, AND THUNDERSTORMS AND MODERATE TO HEAVY RAINS

  • Use temperature-controlled storage to extend the shelf life and maintain the quality of perishable items.
  • Suppress weeds and enrich the soil with organic matter by applying organic mulches that decompose gradually.
  • Cut and clear branches that obstruct sunlight while maintaining windbreaks to prevent soil erosion.
  • Plow or till the soil to break compacted layers, improve aeration, and prepare a fine seedbed. Create drainage channels to manage excess water during heavy rains, especially in waterlogged areas.
  • Calibrate farm tools properly to ensure efficient operations and save fuel.

ENSO ALERT SYSTEM STATUS

(as of 18 December 2024)

Prepare for wetter conditions. Enhance drainage to prevent waterlogging and monitor for pest and disease outbreaks. Use resistant crop varieties and consider staggered planting to avoid peak wet periods. Increased humidity or drought can influence pest and disease prevalence. Conduct of regular monitoring of farm fields and timely interventions are crucial.
