Throw-in type silicate-containing foaming diffusion fertilizer 'Nonepon Tablets'

Cultivating rice that is resistant to pests and diseases! It dissolves quickly after application and spreads evenly to every corner of the field.

The "Nonapon Tablets" are a type of soluble fertilizer containing silicate that excels in absorption, made with water-soluble potassium silicate as the raw material. After application, it dissolves quickly and disperses evenly throughout the field. It prevents lodging of rice plants, and through the reliable absorption of potassium silicate, it strengthens the stem with shorter internodes, thus preventing lodging. 【Features】 - No machinery or tools are needed; simply throw it from the ridge. - The contained potassium silicate has a high utilization rate, increasing the silicate content just below the panicle, fostering rice that is resistant to pests and diseases. - The absorption of potassium silicate increases leaf thickness, reducing the withering of lower leaves after heading, maintaining an upright posture and increasing sunlight exposure, thereby enhancing photosynthetic ability. - The included citric acid promotes the development of new roots, enriching the root zone. - It enhances photosynthetic ability under cold damage and insufficient sunlight, promoting the absorption and digestion of other nutrients. *For more details, please refer to the PDF document or feel free to contact us.

Effervescent tablet-type fertilizer "NK Tab"

Foaming in water! The fast-acting nitrogen and potassium are quickly absorbed, promoting healthy growth.

The "NK (Enu Ke) Tab" is a foam tablet-type fertilizer that can be easily applied by simply throwing it into the rice field. It allows for the easy supply of nitrogen and potassium, which are often deficient after the mid-growth stage. It foams in water, rapidly dispersing its components for quick absorption, allowing for application as needed while monitoring leaf color. 【Features】 ■ Contains citric acid to improve root growth and activate the TCA cycle ■ Quick-acting nitrogen and potassium are rapidly absorbed, promoting healthy growth ■ Improved grain size, leading to increased yield potential ■ Citric acid is transported to the tips of the root zone, revitalizing weakened roots ■ The chelating effect of citric acid enhances the utilization efficiency of each fertilizer component *For more details, please refer to the PDF document or feel free to contact us.
