Farming Advisories
IN AREAS AFFECTED BY ITCZ: DRAIN EXCESS RAIN WATER IN FARM CANALS, CREEKS AND DITCHES; BE ALERT AND HAVE EXTRA CARE TO THOSE LIVING IN LOW LYING AREAS DUE TO POSSIBLE FLASH FLOODING AND LIVING NEAR MOUNTAINOUS OR SLOPING AREAS DUE TO POSSIBLE LANDSLIDES; INSPECT FARM HOUSES AND BARNS (MAKE REPAIRS IF NECESSARY); STORE HARVESTED CROPS IN ELEVATED AND COVERED PLACES. WATER IMPOUNDING IS ADVISABLE DURING HEAVY RAINS FOR FUTURE USE.
IN AREAS WITH MODERATE TO SCATTERED RAINS AND THUNDERSTORMS: FARMERS LIVING IN LOW LYING AREAS AND NEAR MOUNTAIN SLOPES ARE REMINDED TO DO COVER CROPPING, LAND TERRACING AND WATERWAY DECLOGGING ACTIVITIES. THIS IS TO PREVENT SOIL EROSION AND PROVIDE HUMUS, REGULATE WATER, REDUCE WEED, INCREASE BIODIVERSITY AND IMPROVE FARMING AS A WHOLE. KEEP BARNS AND CROP STORAGE ROOMS TO BE IN GOOD, DRY AND WELL VENTILATED CONDITION. DRY WET GRAINS USING MECHANICAL DRYER TO AVOID DETERIORATION.
FOR WET (IRRIGATED) AND MOIST AREAS: LAND PREPARATION (PLOWING, HARROWING, HOEING); WEEDING AND CULTIVATION, PLANTING AND TRANSPLANTING HIGH VALUE CROPS; HARVESTING OF MATURED CROPS; USE COVERED VANS IN DELIVERY OF GOODS IN THE MARKET; PLANTING OF FRUIT TREES TO REPLACE THE OLD ONES.
FOR DRY(RAINFED) AREAS WITH LIGHT TO MODERATE WINDS: SPRAYING PESTICIDES, HERBICIDES, OR FOLIAR FERTILIZER (LIGHT WINDS ONLY). IN AREAS WITH INSUFFICIENT WATER SUPPLY, DRIP IRRIGATION IS ONE ECONOMICAL WAY OF MAINTAINING THE MOISTURE REQUIRED BY THE CROPS; MULCHING CAN ALSO BE DONE TO PREVENT THE RAPID LOSS OF SOIL MOISTURE SO AS TO SUSTAIN THE GOOD GROWING CONDITION OF THE PLANTS.

Fishing Advisories


THE COASTAL WATERS OVER THE EASTERN SECTION OF THE COUNTRY WILL HAVE SLIGHT TO MODERATE SEAS. ELSEWHERE, WILL BE SLIGHT SEAS. FISHERMEN ARE REMINDED TO BE VERY CAREFUL IN GOING OUT TO THE SEA SPECIALLY THOSE USING SMALL SEACRAFT. ALWAYS BRING EMERGENCY KIT. BE UPDATED FOR THE LATEST WEATHER UPDATE AND FARM ADVISORIES.

Philippine Agri-Weather Forecast
The weather systems that will likely affect the whole country are the southwest (SW) monsoon, easterlies, low pressure area (LPA), tropical cyclone, intertropical convergence zone (ITCZ), monsoon trough and localized thunderstorms.

During the start of the forecast period, the southwest monsoon will bring cloudy skies with rainshowers and thunderstorms over Metro Manila and Ilocos region, Cagayan Valley, Cordillera Administrative Region (CAR), Central Luzon and CALABARZON, while partly cloudy to cloudy skies with chances of isolated rainshowers are expected in the remaining areas of the country. After this, Bicol Region, Visayas, Mindanao, and the provinces of Mindoro, Marinduque, Romblon, Aurora and Quezon will experience cloudy skies with rainshowers and thunderstorms due to ITCZ. The rest of the archipelago will have good weather with possible isolated rainshowers. The ITCZ is expected to progress northward and bring cloudy skies with rainshowers and thunderstorms over most areas in Luzon until the end of the first half of the dekad. The remaining portions of the archipelago will have partly cloudy skies to at times cloudy with possible occurrences of rainshowers. During the second half of the forecast period, Visayas, CARAGA, Davao Region, Northern Mindanao, Zamboanga Peninsula, Bicol Region, MIMAROPA, and the provinces of Quezon and Aurora will be cloudy with rainshowers and thunderstorms. As the LPA moves toward north, Luzon and Visayas will experience cloudy skies with rainshowers and thunderstorms, while Mindanao will have gradual improvement of weather condition.

During the first half of the dekad, winds coming from the east to southeast will prevail over Luzon while Visayas and Mindanao will experience winds from the east to northeast. However, the areas in Southern Luzon, Visayas and Mindanao will gradually have winds blowing from the southwest to west during the second half of the dekad. The rest of Luzon will have winds from the northeast to northwest. During the latter days of the forecast period, southwesterly winds will blow over Southern Luzon, Visayas and Mindanao, while the remaining areas of the country will have winds from the southwest to southeast.

During the early days of the dekad, the northern and western seaboards of Luzon will be moderate to rough while the remaining areas of the archipelago will have slight to moderate seas. After this, the whole country will experience slight to moderate seas.

Farm Advisories

(Please observe the Memorandum Order on Stringent Social Distancing Measures and Further Guidelines for the Management of Corona Virus Disease 2019 (COVID-19) Situation)

For nutrient management, one or two days before transplanting, drain water up to field saturation point and apply basal organic and inorganic N fertilizers before final leveling using the recommended rate per hectare. During the wet season - 6 bags-14-14-14 and 8 bags organic. Mix the basal fertilizer thoroughly into the soil. This is a general fertilizer rate recommendation. Determine required NPK through soil analysis or follow local recommendations if there are any.

For zinc-deficient soils, dip seedlings in 2% zinc oxide solution (2g/100 ml water) before transplanting or broadcast 10-20 kg/ha zinc sulfate into the flooded field after the first irrigation. It is important to level the field properly to attain uniform water depth in the field. This helps suppress growth of weeds, and maximizes fertilizer availability in the field.

For additional knowledge to attain potential crop production, farmers are encouraged to join government projects. These will enable them to learn and experience science-based crops and cropping system technologies and gain from such projects’ activities as sample advisories like planting dates, early warning for pest and disease infestation, water management strategies for specific areas, and daily weather condition notifications are available (ex. SARAI project).
