CROP NUTRITION
Nectarines.
Plan by growth stage.
Explore a seasonal NABTA product example for mature nectarines, with growth-stage timing, stage quantities and separate application amounts.
Planning example for agronomic review. These calculations use stated assumptions and are not field-validated NABTA recommendations. Adjust for block tests, crop load, water nutrients, salinity and irrigation capacity before field use. Use current product labels.
Mature-acre rates do not apply to young plantings. Missing information is identified in each program. No yield guarantee or UC endorsement is implied.

How to read this schedule: bold amounts are total product pounds per acre for the entire stage. Divide them across the separate applications shown. Dates are approximate; use actual crop stage. All rates shown are for root-zone fertigation, not foliar spraying.

Assumptions & adjustments
- 100 lb N/ac is the lower end of the UC compilation range 100–150, selected as an example, not a block recommendation.
- 60/40 timing is a proposed adaptation of peach physiology, not a verified nectarine trial schedule.
- K quantity requires tissue/soil interpretation. Early nectarines need a different harvest and postharvest timeline.
- This quantified nitrogen schedule is incomplete as a whole nutrient program. Potassium quantities remain pending; no rate has been borrowed from another crop.
- No routine phosphorus or micronutrient dose is included. These examples assume adequate phosphorus; other nutrients require diagnostic evidence.
- Application counts are arithmetic subdivisions using 30 lb CALTRATE/ac and 20 lb SOP/ac as maximum example event sizes. Confirm current label directions, irrigation frequency, injection capacity, EC and calcium loading. Do not add irrigation solely to fit the schedule.
Product compatibility: apply CALTRATE separately from SOP, MKP, LIB and other phosphate or sulfate solutions, with appropriate flushing. Confirm the current California registration and label for SOP before purchase or use; its current status has not been verified for this example.
Research basis: UC / CDFA crop nutrition reference. Product analyses: CALTRATE label reference · SOP label reference. These references do not imply UC endorsement of NABTA products.
