AREAS AFFECTED BY THE WEATHER SYSTEMS
SOUTHWEST MONSOON, LPA, THUNDERSTORMS AND MODERATE TO HEAVY RAINS
- Wet weather promotes fungal development and can cause damage to stored farm products, reduce the quality, viability and market price of the grains. Thus, it is advised to keep barns and crop storage rooms in good, dry, and well-ventilated condition.
- Mulching helps protect the soil from erosion caused by wind and rain. It reduces the impact of raindrops on the soil surface and slows down water runoff, allowing more water to infiltrate the soil.
- Use controlled irrigation systems that allow precise water application to avoid oversaturation. Implement systems to capture and store rainwater for controlled use, reducing surface water accumulation.
MONTHLY CLIMATE ASSESSMENT AND OUTLOOK
LA NIÑA ALERT
https://bagong.pagasa.dost.gov.ph/climate/el-nino-la-nina/monitoring
Wet conditions can increase the incidence of pests and diseases. Monitor crops regularly for signs of fungal infections, blights, and pest infestations. Apply mulch to retain soil moisture and prevent erosion during heavy rains. Cut back on irrigation schedules to avoid over-saturating the soil. Prepare drying facilities for harvested crops to prevent spoilage due to high moisture levels. Inspect and repair farm buildings, storage facilities, and equipment to withstand heavy rain and strong winds. After heavy rains, there is usually a surge in weed growth. Immediate weeding is essential to reduce competition for nutrients.
