Bio 20

Bio 20 is a complete foliar nutrition solution from OMEX, containing a unique package of nutrients, biostimulants and micronutrients optimised for foliar application.

Bio 20 can be used as a standalone NPK foliar fertiliser or as a feed and plant growth stimulant in times of plant stress. Bio 20’s carefully balanced mix of water soluble biostimulants and nutrients is designed to stimulate root growth and nutrient uptake more effectively than the same ingredients applied separately.


All agricultural and horticultural crops benefit from Bio 20’s complete foliar nutrient formulation. It can also be used on turf. 

Bio 20 can be used as a foliar feed and plant growth stimulant, particularly in times of stress, or as part of your regular comprehensive nutrient management programme.

Bio 20 provides the benefits of naturally occurring kelp and a balanced combination of macro and micro nutrients.

The biostimulants and nutrients found in Bio 20 improve root growth and nutrient uptake to a greater level than when the two are applied separately.

Bio 20 can be used to the best effect when the crop is under stress but specific deficiencies should be treated with the relevant foliar product.


Apply 3 l/ha for most crops or 2-5 l/ha for potatoes, in a minimum of 200 l/ha water.

If the target is small, foliar uptake will be enhanced by the addition of NA13¹.
The spray tank should be filled with half the required water.

After shaking the container, measure the required amount of Bio 20 and add to the tank whilst maintaining constant agitation. Add remaining water to correct dilution and spray.

Crop Timing Rate l/h Comments
Cereals 2-6 leaves to 1st node 3 Apply if soil and weather conditions prevent optimum growth or to relieve crop stress.  Promotes root growth and improves uptake of nutrients from the soil
Oilseed Rape Early spring growth 3 Apply if soil and weather conditions prevent optimum growth or to relieve crop stress.  Promotes root growth and improves uptake of nutrients from the soil
Legumes, Vegetables, Grassland, Fruit As required or when stress is evident 3 Repeat as necessary every 10 - 14 days
Lettuce module drench Onto module   Apply 4 ml/m2.  Boosts plants prior to transplant

3 - 4 weeks after emergence






Promotes root growth and improves canopy cover

Follow with 2 - 3 applications at 14 day intervals once crop meets across the rows

Seedling/module drench Onto module   2l in 1000l water (2ml/l).  Reduces transplant shock, stimulates rapid field establishment
Sugar Beet 4 - 8 leaf stage 3 Promotes root growth, protects against stress


Bio 20 can also be used as a foliar fertiliser on a wide range of crops to improve crop colour and increase vigour and growth. Visual effects on many crops can be seen within a few hours of application in some situations.

Do not apply in tank mix with pesticides when crop is showing deficiency symptoms, is under stress, or in adverse weather conditions.

For further information on compatibility and tank mixing, and for physical compatibility with pesticides refer to the website

¹ NA13 is an adjuvant designed to help with improved adhesion, deposition and penetration of the spray solution on the leaf surface. NA13 should be added at 0.1% of the spray volume, e.g. 100 ml in 100 litres of water. Maintain agitation and apply immediately after mixing.


Bio 20 is a complete foliar nutrient formulation with the added benefit of a powerful biostimulant.


Bio 20 is ideal for a wide range of horticultural crops as a standalone fertiliser, and for stress relief and plant health promotion on protected edibles, bulbs, hardy nursery stock, ornamentals and soft and tree fruit.

Turf and Amenity

Containing a balanced ratio of N:P:K plus a full range of secondary and micronutrients, it feeds turf swards without enriching the soil. The full benefit of foliar application is therefore achieved without any risk of increasing phosphate levels in the soil and without any effect on sward composition.

Bio20 is ideal for regular spoonfeeding to maintain turf colour and vigour, whilst boosting growth in the root zone to improve drought tolerance and wear resistance.

When to use How much to use Comments
General all year feed 0.5 litres/green, 10 litres/ha Repeat as required to maintain colour and vigour
