GRANULAR ORGANIC FERTILISER FOR LARGE AREAS
Biosol 25 kg
When the garden is large, organic feeding needs a quantity that can genuinely cover its requirements. Biosol 25 kg provides organically bound nitrogen that becomes available gradually through soil life, while its high organic-matter content contributes to more humus, better structure and more effective water retention. It is the practical large pack for extensive beds, vegetable gardens, fruiting plants and lawns, without relying on numerous small packs.

Gradual nutrition with meaningful care for the soil
Biosol is made from organic fungal biomass. Most of its nutrients are bound within the organic matter and released through the activity of soil organisms, instead of being supplied all at once with the first watering.
- Organic nitrogen 6–8%: feeds plants gradually as it is made available by soil life.
- Water-soluble nitrogen up to 0.5%: most of the nitrogen is not present in an immediately soluble form.
- Phosphorus and potassium: contains 0.5% P₂O₅ and 0.3% K₂O for supplementary base nutrition.
- Fungal biomass: provides organic material that supports humus and soil activity.
Nutrition released gradually
The organically bound nitrogen is made available through soil microorganisms, providing a steadier supply than an immediately soluble fertiliser.
Better soil quality
The high organic-matter content contributes to humus formation, a more stable soil structure and improved water retention and movement.
Large quantity, fewer packs
The 25 kg pack serves extensive areas and numerous plantings, allowing the same organic nutrition to be applied consistently across the whole garden.
When and where to use it
For gardens with genuinely larger requirements
It is particularly useful when you want organic nutrition with an emphasis on nitrogen and also need enough product to improve soil that is poor, tired or low in organic matter.
Large beds
For flowering plants, herbs, shrubs and mixed planting schemes with numerous application points.
Vegetable garden
For tomatoes, peppers, potatoes, cucurbits, brassicas and other vegetables.
Fruiting plants
For fruit trees, citrus, vines, berries and other productive plantings.
Lawns & large areas
For even distribution across lawns and extensive garden zones.
A large pack with straightforward measuring
The pack is large, but application remains simple. Weigh the correct rate for each square metre or litre of growing medium, distribute it evenly and water afterwards.
- High requirements: 150–200 g/m²
- Lower requirements: 80–120 g/m²
- Pots: 4–6 g/L of growing medium
- Poor soil: +50 g/m²
- Water afterwards: yes
Before planting, use 150–200 g per square metre and work the granules lightly into the upper layer of soil.
For plants with lower requirements, use 80–120 g per square metre, starting at the lower rate.
When preparing or refreshing the growing medium, mix 4–6 g of product into each 1 litre of growing medium and distribute it thoroughly throughout.
In poor or tired soil, you can add 50 g/m² after approximately 10 weeks. Spread over the surface, work in lightly and water.
Do not add it to water or apply it over the plant
Biosol is a granular soil fertiliser: do not dissolve it for root watering and do not spray it onto the leaves. Do not leave concentrated granules touching stems, the plant crown or young plants directly.
Twenty-five kilograms for up to 312.5 m² of soil
Actual coverage depends on the plants' requirements. At the lower rate, the pack covers up to 312.5 m², while at the maximum rate for hungry plants it covers 125 m².
80 g/m²312.5 m²lower rate
120 g/m²≈ 208.3 m²per application
150 g/m²≈ 166.7 m²per application
200 g/m²125 m²maximum rate
Calculation basis: 25,000 g of product divided by the selected rate per square metre.
