Generally, products are tailored to the fertilizer requirements of the crop, so they are not significantly affected by soil fertilityth just a single application.

  • Nitrogen: It is the component that has the greatest impact on crop growth, and even after the growing season ends, a significant amount is lost due to volatilization, leaching, and denitrification, leading to minimal accumulation in the soil. Therefore, it needs to be supplied annually at a certain rate. Hence, the presence of nitrogen-rich soils is not common, so recommending the application rate of CRF fertilizers poses no issues.
  • Phosphorus, Potassium: These components are greatly influenced by soil fertility. However, potassium and phosphorus exist in the soil in an insoluble state, but as plants grow, their roots convert this insoluble form into an available form, resulting in minimal problems. Especially in Korea, there is an excessive accumulation of available phosphorus, so CRF fertilizers are formulated taking this into account.
  • Additionally, these components (phosphorus, potassium, etc.) are being highly concentrated, leading to salt damage in greenhouse cultivation areas. However, using dibbling fertilizers minimizes the application rate, thereby reducing the risk of salt damage in greenhouse cultivation areas.
