TECHNOLOGIES
Soil Science Division - Phosphorous Fertilizer Application in Alternative Seasons in Rice Cultivation
Technology
- Apply P fertilizer at the rates recommended by the Department of Agriculture only in Yala season (at the rate of 55 kg/ha for irrigated paddy and 35 kg/ha for rainfed paddy)
- This can be practiced when soil P level is above 5 mg/kg. So, Check soil P levels using soil P maps before practicing
Benifits
- Saved 50% of the Phosphorous fertilizer (TSP) application in paddy cultivation
- Reduced soil and water pollution
