Ilocos tillers learn right way to apply fertilizer
Investigators found that it had been applied as a side-dress rather than by the recommended basal method.

Concerns over “insoluble and floating” fertilizer in Ilocos Norte have been traced to their improper application by farmers, not defective products, easing fears about the integrity of government farm input programs.
The Department of Agriculture (DA) on Friday said the issue emerged after a farmer, Esting de la Cruz, posted a video showing fertilizer granules blown by strong wind toward a ricefield embankment, sparking questions about the quality of the fertilizer distributed under government programs.
The DA Regional Field Office I conducted a field validation on 21 and 22 December, coordinating with provincial and municipal rice program coordinators and the municipal agriculturist to verify the claims.
Field checks confirmed that the fertilizer used was DANAT Complete Fertilizer (14-14-14) that was procured through the local government.
Investigators found that it had been applied as a side-dress rather than by the recommended basal method. This, combined with the windy conditions, the DA said, caused the granules to remain on the soil surface and appear insoluble or defective.
The agency held an on-site briefing to explain the correct application process to the farmers and prevent future mistakes.
In fertilizer application, the basal method involves applying the fertilizer to the soil at or before planting, usually incorporated into the soil so nutrients are immediately available to the developing roots. This method promotes uniform nutrient distribution and early plant growth.
In contrast, side-dressing is done after the crop has emerged, with the fertilizer placed on or near the soil surface alongside the growing plants to supplement the nutrients during later growth stages.
When side-dressing is improperly done, especially under windy or dry conditions, fertilizer granules may remain on the surface, increasing the possibility of nutrient loss.
“All fertilizer distributed under DA programs undergo mandatory quality testing before delivery, with additional re-testing and quality control through DA laboratories or Fertilizer and Pesticide Authority-accredited facilities,” the DA said.
It said it will continue to monitor fertilizer use in the Ilocos and step up farmer briefings to ensure correct utilization and protect the integrity of government farm inputs.
