FARMING ADVISORIES

ITCZ, EASTERLIES, THUNDERSTORMS AND MODERATE TO HEAVY RAINS • Provide shade cloth or temporary shelters for delicate seedlings during the peak afternoon heat to protect them from excessive sun exposure. • Use organic mulch, like straw or grass clippings, to help cool the root zones and maintain consistent moisture levels in the soil. • Schedule fieldwork during early mornings or late afternoons to avoid the hottest part of the day and reduce heat stress on both workers and crops. • Check storage areas for harvested crops (e.g., rice, corn, fruits, and vegetables). If necessary, move crops to elevated or covered areas to prevent water damage. Ensure farm equipment is stored in dry, sheltered locations to prevent rusting or malfunction. • Heavy rains increase the risk of soil erosion. Take preventive measures like reinforcing embankments, creating terraces, or planting ground cover to stabilize the soil and prevent it from washing away.

ENSO ALERT SYSTEM STATUS

Ensure proper drainage in their fields to prevent waterlogging. Regular application of integrated pest management is important to minimize pest damage on key crops such as rice, corn, and vegetables. Harvested grains and produce must be stored in dry, covered areas to avoid mold and spoilage caused by humidity. Additionally, adopting conservation agriculture practices like crop rotation, cover cropping, and reduced tillage helps improve soil health and retain moisture, supporting better crop growth throughout the season.
