Foliar Fertilizers: What Buyers Should Know
Foliar fertilizer delivers nutrients directly through the leaf surface for rapid correction of deficiencies and a fast yield response during critical growth stages. Buyers source foliar fertilizers from China as liquids and soluble powders blending NPK with trace elements, amino acids, and humic acids.
The key specifications are solubility, nutrient balance, wetting agents, and phytotoxicity risk. Fine particle size and good spreading improve leaf absorption. The curated suppliers below are screened against these criteria.

7 Checks Before Choosing a Foliar Fertilizers Supplier
1. Solubility
Confirm complete water solubility with no residue or clogging.
2. Nutrient balance
Match NPK plus trace elements to the growth stage and deficiency.
3. Wetting agents
Good surfactants improve droplet spread and leaf absorption.
4. Phytotoxicity
Test on a small area first; avoid high salt index on sensitive crops.
5. Compatibility
Verify tank-mix compatibility with pesticides and other nutrients.
6. Application timing
Spray in cooler hours and avoid rain within a few hours of application.
7. Packaging
1L to 1000L for liquids and 1kg to 25kg for powders; confirm shelf life.
Frequently Asked Questions
What is foliar fertilizer?
It is a liquid or soluble-powder nutrient applied directly to leaves for fast absorption and quick correction of nutrient deficiencies.
When should I apply foliar fertilizer?
Apply during critical growth stages, in the early morning or late afternoon, and avoid spraying before rain.
Can foliar fertilizer replace soil fertilizer?
No. Foliar feeding supplements soil nutrition for quick response but cannot supply the full nutrient demand of most crops.
What is the MOQ for foliar fertilizers from China?
Typically 5-10 metric tons for powders and a few hundred liters for liquids; see each supplier profile.
