Farming Advisories
IN AREAS AFFECTED BY INTERTROPICAL COVERGENCE ZONE (ITCZ), NORTHEASTERLY SURFACE WINDFLOW, AND MODERATE TO HEAVY RAINS
Be alert and extra careful to those living in low lying areas and near mountain slopes due to possible flooding and landslides; During the rainy season, farmers are advised/ reminded to do cover cropping, land terracing and waterway de-clogging activities. This is to prevent soil erosion and provide humus, regulate water, reduce weed, increase biodiversity and improve farming as a whole. Continuous 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 to be in good, dry and well-ventilated condition. Clean creeks, canals and ditches; store harvested crops in elevated, well ventilated and covered places. Water impounding is advisable during heavy rains for future use.

FOR WET (IRRIGATED) AND MOIST AREAS
Livestock/domesticated animals are susceptible to contract diseases during the rainy period, always keep animal shelters and its surroundings clean, dry and well ventilated. A clean environment can minimize the possibility of covid-19 infection. Land and seedbed preparation; planting and transplanting; removal of weeds and cultivation, 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
Watering crops during early morning and evening periods will help alleviate stress on crops. Sun drying of newly harvested rice and corn; watering activities or irrigation using pump in dry and rainfed areas. Spraying insecticides or fertilizer application in farm areas with light winds when needed.
Fishing Advisories

Rough to very rough seas will be experienced over the seaboards of Northern and Western Luzon (Batanes, Babuyan Island and Ilocos Norte) while the rest of the archipelago will have slight to moderate seas. Be reminded to be very careful in going out fishing specially those using small sea craft. Always bring emergency kit. Be updated for the latest weather update and farm advisories.

Red Tide Alert

10 - Day Regional Agri-Weather Information

DEKAD NO. 29      11 – 20 October 2021

Philippine Agri-Weather Forecast
The weather systems that will likely affect the whole country are the southwest monsoon, Intertropical Convergence Zone (ITCZ), low pressure area (LPA), tropical cyclones, easterlies, and localized thunderstorms.

During the start of the forecast period, most areas in Northern Luzon will experience stormy weather while Visayas, BARMM, Zamboanga Peninsula and the remaining parts of Luzon will have cloudy skies with scattered rainshowers and thunderstorms. Good weather condition is expected over the rest of the country except for chances of isolated rainshowers. As the tropical cyclone moves westward towards the West Philippine Sea, gradual improvement of weather will be experienced over the areas affected by the weather disturbance. After this, the western sections of Luzon and Visayas will continue to be cloudy with rainshowers and thunderstorms while the rest of the country will experience partly cloudy to cloudy skies with chances of isolated rainshowers or thunderstorms. During the latter part of the forecast period, Eastern Visayas, Bicol Region, CARAGA, and the provinces of Aurora and Quezon will be cloudy with rainshowers and thundertsorms. The rest of the archipelago will have improved weather condition aside for having possible occurrences of rainshowers or thunderstorms.

During the start of the dekad, winds coming from the southwest will prevail over Mindanao while the rest of the country will have winds from the northwest to southwest. Gusty winds may be experienced in areas affected by the tropical cyclone. As the weather disturbance moves westward, away from the country, southwesterly windflow will gradually prevail over Visayas and Mindanao while Luzon will have winds blowing from the southwest to southeast. During the mid of the forecast period, winds from the northeast will be experienced over Northern Luzon while the rest of Luzon will have winds from the southwest to northeast. Southwesterly winds will continue to prevail over Visayas and Mindanao. After this, southerly winds will blow over the archipelago except in extreme Northern Luzon where northeasterly winds are expected to be experienced. During the latter days of the dekad, winds from the northeast to south will blow over Luzon while the remaining areas of the country will have winds from the northeast.

During the early days of the forecast period, rough to very rough seas will be experienced over the whole archipelago. After this, the seaboards of Luzon will be moderate to rough while the remaining coastal waters of the country will have slight to moderate seas.

Transition from ENSO-neutral conditions to La Niña is favored in the coming months with 70-80% chance of La Niña forming in the last quarter of 2021 which may persist until the first quarter of 2022
Farm Advisories

Modernizing agriculture thru farm mechanization

In its quest to modernize agriculture, the Department of Agriculture (DA) in Caraga continuously implements the farm mechanization program.

On July 7–8, 2021, DA-Caraga Regional Corn Program turned over two units of 4-wheel drive farm tractors amounting to P2.45 million to each corn farmers’ association in the provinces of Agusan del Sur and Surigao del Sur.

The recipients of the said tractors were Sta. Irene Integrated Farmers Association (SIIFARMAS) of the town of Prosperidad, Agusan del Sur and MALCATRIVO Corn Farmers Association of Brgy. Osmeña, Tagbina, Surigao del Sur

The said interventions were based on the needs of the farmers as stipulated on their cluster development plan to make corn farming more productive and help attain economies of scale,” DA-Caraga Field Operations Division Chief Melody Guimary said.

MALCATRIVO Chairperson Ruben Lacasaca said that farm tractor is a big saving for them since a hectare of field using the traditional carabao would take one week to plow but with the tractor, it would take only at most of 2 hours.

The rent for a carabao and a man would costs around P700.00 a day or a total of P4,900.00 for a week job while on the tractor the payment is only P2,300.00 and it can be done in just 2 hours.

“With this farm tractor, our members would be encouraged more to cultivate their land since it is a big sigh of relief from land preparation expenses and more free days to attend to other important matters,” SIIFARMAS Chairperson Antonio Marti l, Jr. said.

Regional Technical Director Rebecca Reyes Atega explained that nowadays giving of interventions, not only farm tractor but to include other needs of the farmers is focused on clusters in line with the DA’s Farm and Fisheries Clustering and Consolidation (F2C2) Program or the Bayanihan Agri Clusters (BACs).

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 also available (e.g., ACIAR, SARAI projects, etc
