FARMING ADVISORIES

AREAS AFFECTED BY THE WEATHER SYSTEMS
LPA, 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.
