Fertigroe® nanofertilizers are slow-release formulations of nitrogen (N), phosphorus (P), and potassium (K). These nutrients are encapsulated inside a “carrier,” which protects the nutrients from direct contact with the soil environment. These are “slow-release” because the nutrients are released to plant parts just in time or at a point in the growth stage where plants need them most. This makes nutrient use more efficient and effective. Applying FertiGroe® nanofertilizers is easy. These are placed along the furrow, then covered with a thin layer of soil before planting the cane seeds. For ratoon, the nanofertilizers are applied along the side, at around 2 inches from the roots, prior to hilling-up. The product comes in powdered and granulated forms.Field experiments in La Carlota City, Negros Occidental showed yield gains of up to 95 ton-cane per hectare (TC/ha), which is more than the annual average of 60 TC/ha in the Philippines.
