17Ideal Fertilizer Timing Delayed Flood
- P K
- Just prior to planting, incorporated
- On soil surface ahead of flush
- On soil surface ahead of permanent flood
18Ideal Fertilizer Timing Pinpoint Flood
- P K
- In the fall following seedbed preparation and
prior to flooding during winter - Into the flood immediately following water
leveling allowing the sediment to cover it - Onto the soil surface during the brief drain
interval between draining and establishment of
permanent flood
19Ideal Fertilizer Timing Delayed Flood
- Nitrogen
- Small amount ahead of flush fb 2/3 just ahead of
permanent flood then topdress at mid-season - All day of or just prior to permanent flood
20Ideal Fertilizer Timing Pinpoint Flood
- Nitrogen
- Apply 2/3 to ¾ during the brief drain interval
between draining and establishment of permanent
flood - Follow with remainder at mid-season
21Phosphorus Potassium Rates
- Should be based on a soil test
- Plant response always bottom line
- Range
- Phosphorus 0 to 60 lb/A
- Potassium 0 to 120 lb/A
- Typical Rates
- Phosphorus 20 to 40 lb/A
- Potassium 40 to 70 lb/A
22Nitrogen Rates
- Based on crop response in research plots
- Range of rates
- Need to know response in each variety by field
situation - History important
- Growing conditions important
- Water management critical
23When to Adjust Fertilizer Rates
- In high pH soils especially when P test is high
but there is a history of P deficiency - When a nutrient deficiency symptom is diagnosed
- When fertilizer may have been lost

35Even though we are anticipating higher input
costs than ever before strong prices and good
yields still make rice a profitable crop in many
situations especially where other crops are not a
viable option.
