Micronutrients are needed in tiny amounts, but a shortage can cost far more yield than their price suggests. Boron, zinc, iron, manganese, copper and molybdenum control flowering, enzyme activity and chlorophyll formation. When they run short, crops suffer “hidden hunger” — lower yield and quality before obvious symptoms even appear.
Key takeaways
- Boron is critical for pollination, fruit set and calcium movement into fruit.
- Liquid micronutrient mixes correct several deficiencies in one application.
- Alkaline, sandy and high-pH soils — common in the Gulf and parts of Africa — often lock up micronutrients.
- Boron has a narrow safe range: always follow recommended rates.
Why boron matters
Boron supports pollen viability and pollen tube growth, flower retention, fruit set and the transport of sugars and calcium. Boron-deficient crops often show poor flowering, flower and fruit drop, hollow or cracked stems, deformed fruit and thick, brittle new leaves. Fruit trees, cotton, oilseeds, brassicas, root crops and many vegetables are especially sensitive.
Boron 10% liquid
Our Boron 10% is a concentrated liquid for correcting boron deficiency through foliar spray or drip. It is typically applied before and during flowering to improve pollination and fruit set. Because the gap between enough and too much boron is narrow, apply only at recommended rates and avoid repeated heavy doses. Boron also pairs well with our calcium liquids, since the two nutrients work together in fruit development.
What is hidden hunger?
Hidden hunger is a nutrient shortage that reduces yield or quality without clear visible symptoms. By the time leaves yellow or growth stalls, much of the yield potential may already be lost. It is common where soils are alkaline, sandy or low in organic matter, where intensive cropping has mined nutrients, and where high-analysis NPK is used without micronutrients.
| Micronutrient | Main role | Common deficiency sign |
|---|---|---|
| Zinc (Zn) | Growth hormones, enzyme activity | Small, narrow leaves; stunted growth |
| Iron (Fe) | Chlorophyll formation | Yellow young leaves with green veins |
| Manganese (Mn) | Photosynthesis | Mottled yellowing between veins |
| Boron (B) | Flowering, fruit set | Flower drop, deformed fruit |
| Copper (Cu) | Enzymes, lignin | Wilting, dieback of tips |
| Molybdenum (Mo) | Nitrogen metabolism | Pale leaves, poor nitrogen use |
Liquid Mix Micronutrient Fertilizer
Our liquid micronutrient mix is a balanced blend of essential micronutrients designed to correct hidden hunger, improve leaf colour and support healthy growth and yield. Being liquid, it mixes easily for foliar spray — the fastest way to deliver micronutrients when soil conditions limit uptake — and can also be applied through drip.
Best practice for micronutrient application
- Use soil and leaf tests to identify which micronutrients are short.
- Spray in the cool of early morning or late afternoon to improve absorption and reduce leaf scorch.
- Apply ahead of critical stages — before flowering for boron, during early growth for zinc and iron.
- Jar-test before tank-mixing with other fertilizers or crop protection products.
- Build soil health with natural organic inputs, which improve micronutrient availability over time.

Frequently asked questions
When should I apply boron fertilizer?
Boron is most effective just before and during flowering, when it supports pollination and fruit set. Follow the recommended rate, as excess boron can be harmful.
What is the difference between a micronutrient mix and NPK + TE?
NPK + TE grades contain small amounts of trace elements alongside NPK. A dedicated micronutrient mix supplies higher levels to correct existing deficiencies.
Can liquid micronutrients be applied through drip irrigation?
Yes. They can be applied by drip or foliar spray. Foliar spray is fastest when alkaline soil limits uptake.
Do you supply micronutrient fertilizers in private label?
Yes, in cans and drums with your own branding.
