Amino Acid Programmes For Greenhouse And Open-Field Vegetables
Fruit set, uniform sizing and stress recovery under protected cultivation
The Constraints In This Crop
- Fruiting vegetables carry their whole margin in grade-out: uniform sizing and shelf life decide the price, not raw yield.
- Protected cultivation concentrates salts in the root zone, and salinity stress shows up first as stalled fruit set.
- Transplant shock and heat events cost days of growth that the crop never recovers within the cycle.
- Drip systems punish any input that is not completely soluble, and emitter blockage is expensive to clear.
What The Programme Has To Deliver
- An input that runs through drip lines without residue
- Rates that work both as a weekly fertigation dose and as a foliar spray between events
- A grade that can be stepped up after a stress event without changing product
- Documentation good enough for import registration in the destination market

Programme Note 1
Fertigation at 1.5 to 3 kg per hectare weekly through the growing period.
Programme Note 2
Foliar at 0.1 to 0.2% every 10 to 14 days, timed to transplant recovery, flowering initiation and fruit development.

Which grade should this crop start with?
Amino Acids 45. Amino Acids 45 for balanced programmes, stepping up to Amino Acids 80 for salinity and heat-stress recovery.
Do you provide crop-specific programmes?
Yes. Send the crop, the area, the current programme and the climate, and our team returns a grade, rate and timing recommendation.
How are the rates expressed?
Foliar rates are given as grams per 100 L of spray and as a percentage solution; fertigation and soil rates are given per hectare per application.
Can the powder be tank mixed with what we already spray?
Run a jar test with the intended tank partners at field concentration before committing a full tank.
What documentation ships with an order?
A batch-specific COA with every shipment, with TDS and SDS available before the order.
