Farmers Advisories
As rainfall has gradually commenced, vegetation is becoming denser, and rainfall is predicted to moderately increase in the coming dekads of May. Additionally, soil moisture is gradually improving. Farmers are therefore strongly encouraged to take the following precautions in their agricultural practices:
· Field Preparation:
Move to upland areas for their vegetable and rice production; this will help reduce the risk of damage and maximize yields for farmers across the country.
Create drainage channels in low land where possible to prevent waterlogging in case of heavy rainfall.
Farmers are advised to properly lay out their fields for rice production during the coming season.
Farmers are also advised to begin preparing upland areas for rice and other crops ahead of the upcoming cropping season.
· Crop Management:
Plant drought- or water-tolerant crop varieties to reduce the risk of losses.
Monitor crops regularly for signs of disease or stress caused by high evapotranspiration.
Irrigate when high evaporation and evapotranspiration are observed.
· Livestock Management:
Move animals to upland areas to avoid being affected by heavy rainfall.
Ensure animals are properly housed and maintain good hygiene to prevent disease outbreaks.
Provide clean drinking water regularly to prevent dehydration and heat stress.
Check livestock frequently for symptoms of illness and provide timely treatment when needed.
· General Precautions:
Stay informed about weather updates through the Liberia Meteorological Service website (https://meteoliberia.com).
Work closely with local agricultural extension officers for region-specific advice on crop and livestock management.
