Foliar Fertilizer Programmes
Direct leaf application at 0.1 to 0.2% for rapid uptake and stress resistance
What This Method Covers
Foliar application puts amino acids on the leaf surface during the growth stages that decide the crop, rather than waiting for root uptake from the soil solution. Every Everwell grade dissolves completely, so the spray tank carries no residue into the nozzles and the same product can be used at the low end of the dilution range on sensitive crops and at the high end on established canopies.
Step By Step
Pick the grade by spray volume
Amino Acids 35 and 45 are dosed at 100 to 200 g per 100 L of water. Amino Acids 80 covers the same active load at 50 to 150 g per 100 L, which matters when water is carted.
Dissolve before filling
Pre-dissolve the powder in a partly filled tank with agitation running, then top up. All grades reach full solution; the 80 grade needs no more mixing time than the 35.
Time to the growth stage
Apply every 10 to 14 days through the active growth window, and after transplanting, flowering initiation, fruit development or a stress event.
Check compatibility before mixing
Run a jar test with the other tank partners at field concentration before the first full tank.
Record the response
Note the stage, rate and interval used so the programme can be repeated or adjusted on the next cycle.

Read moreQuestions About This Method
What do you need from us to recommend a rate?
The application, the target active content, the batch size and the other components of the formulation.
Which grade is normally specified for this method?
Amino Acids 45 is the usual starting point. Amino Acids 35 and 45 are dosed at 100 to 200 g per 100 L of water. Amino Acids 80 covers the same active load at 50 to 150 g per 100 L, which matters when water is carted.
Does the powder dissolve fully in this method?
Water solubility is specified at 100% for the amino acid grades and 99% for Protein Powder, so nothing is left in tanks, drip lines or dosing equipment.
Can we sample before committing?
Yes. Free samples of 200 to 500 g ship with their own batch COA for formulation testing.
What is the lead time for a commercial order?
30 days for regular orders, FOB Shanghai or Qingdao.
