Concerns over “insoluble and floating” fertilizer in Ilocos Norte were traced to improper application by farmers, not defective products, easing fears about the integrity of government farm input programs.

In a statement on Friday, the Department of Agriculture (DA) said the issue surfaced after farmer Esting Dela Cruz posted a video showing fertilizer granules blown by strong winds toward a rice field embankment, raising questions about the quality of fertilizers distributed under government programs.

The DA’s Regional Field Office I conducted a field validation on 21 to 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), procured through the local government.

Investigators found that the fertilizer was applied as a side-dress rather than through the recommended basal method. According to the DA, this, combined with windy conditions, caused the granules to remain on the soil surface and appear insoluble or defective.

The agency conducted an on-site briefing to explain the correct application process and prevent similar incidents.

“All fertilizers 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.

The DA said it will continue monitoring fertilizer use in Ilocos and step up farmer briefings to ensure proper utilization and protect the credibility of government farm input programs.
