- Temperature
– Generally, when the temperature increases by 10°C from 25°C, the release rate doubles. However, this may vary depending on the coating material.For example, at 25°C: release period is 90 days / at 35°C: release period is 45 days.
– Conversely, when the temperature decreases by 10°C from 25°C, the release rate decreases twice
For example, at 25°C: release period is 90 days / at 15°C: release period is 180 days.
– No release occurs at temperatures below 5°C
- Humidity
– If there is no humidity, there will be no release. However, under soil moisture conditions, the release occurs adequately, ensuring no issues. In other words, under the soil moisture conditions conducive to crop growth, fertilizer release occurs sufficiently.– However, when applying fertilizer on the surface without burying it in the soil, the release depends on the humidity in the air, which may result in lower fertilizer release. Therefore, it is essential to apply the fertilizer in the soil
