Fertigation And Drip Delivery
1 to 3 kg per hectare through the irrigation line, straight to the root zone
What This Method Covers
Fertigation delivers amino acids and organic nitrogen into the root zone with the irrigation water, which suits protected cultivation and any crop already on drip. The constraint is solubility: an input that only partly dissolves will find the emitters. All Everwell grades are 100% water soluble, so they can be dosed through venturi injectors and dosing pumps without leaving sediment in the line.
Step By Step
Confirm the dose per application
1 to 3 kg per hectare per application is the general range, with 1.5 to 3 kg weekly typical on vegetables through the growing period.
Prepare a stock solution
Dissolve the powder into a stock tank with agitation rather than adding powder directly to the injection line.
Inject during the nutrient window
Feed during the middle of the irrigation event, not at the start or the flush, so the dose reaches the root zone rather than the far end of the line.
Flush the line after dosing
A clean water flush at the end of the event keeps residue out of emitters regardless of what was injected.
Validate against water quality
Hard water and high-salt sources change how blends behave. Confirm compatibility with a jar test on your own water before committing a full 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. 1 to 3 kg per hectare per application is the general range, with 1.5 to 3 kg weekly typical on vegetables through the growing period.
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.
