SPECTRUM BROAD RANGE FOLIAR MICRONUTRIENT
Spectrum – Broad Range Foliar Micronutrient for Arable & Field Vegetable Crops
Spectrum Broad Range Foliar Micronutrient Use:
Spectrum is a high-efficiency, balanced foliar micronutrient mix designed to provide broad-spectrum crop support across arable, field vegetable and horticultural crops.
It contains sulphur, manganese, zinc, iron, copper, boron and molybdenum in a water-soluble formulation designed for easy mixing, enhanced compatibility and efficient uptake. Spectrum helps make micronutrient nutrition less dependent on unfavourable weather and soil conditions, supporting even application and precise timing during periods of high crop demand.
Key benefit:
Broad-spectrum micronutrient support in one foliar treatment
Spectrum provides a wide range of essential micronutrients in a single foliar product, helping support balanced crop nutrition from the early stages of foliar growth and development. It is particularly useful where multiple trace element requirements need to be addressed as part of a crop nutrition programme.
Benefits:
- Provides broad-spectrum micronutrient support.
- Contains sulphur, manganese, zinc, iron, copper, boron and molybdenum.
- Helps support crop growth and nutrient balance.
- Supports precise timing of micronutrient applications during periods of high crop demand.
- Helps make micronutrient nutrition less dependent on dry soils and unfavourable weather.
- Allows even foliar application across the crop canopy.
- Suitable for repeated lower-rate applications rather than one large dose.
- Designed for easy mixing, enhanced compatibility and efficient uptake.
- Suitable for arable, field vegetable and horticultural crops as part of a nutrient recommendation programme.
When and where to use:
Spectrum should be applied as a foliar nutrient treatment when there is enough leaf area to absorb the spray. In most crops, this normally coincides with the 3-leaf stage onwards.
Repeated applications at lower rates are usually preferable to one large dose. For best uptake, applications should be made in the early morning or late evening.
Crops:
A wide range of arable, field vegetable and horticultural crops as part of a specific nutrient recommendation programme.
Pack Size:
10 kg

Application – Spectrum
General application guidance
- Apply as a foliar spray when sufficient leaf area is present.
- In most crops, this normally coincides with the 3-leaf stage onwards.
- Repeated applications at lower rates are usually preferable to one large dose.
- Apply in the early morning or late evening for best nutrient uptake.
- Half-fill the sprayer with water.
- Start agitation.
- Add the appropriate OptiYield nutrition products first.
- Slowly add the required quantity of Spectrum to moving water.
- Top up the spray tank with the remaining water.
- Mix well before spraying.
- Do not allow the spray mixture to stand idle.
- Use only where there is a recognised crop need.
- Do not exceed the appropriate application rate.
- Wash hands before meals and after work.
- Safely dispose of empty containers.
