BIOS Fertile D+ — Organic NP Fertilizer
BIOS Fertile D+ is a balanced organic NP fertilizer built from top-quality animal proteins that are naturally high in amino acids and peptides. Its formula was refined through field trials run by our technical team together with the hands-on experience of seasoned growers. The result is a soil feed with a gradual, programmed nutrient release that keeps working for 6 to 8 months, yet still delivers nutrition from the very first application.

Supplied as a powder or in pellet form, BIOS Fertile D+ mixes readily into the soil, which speeds up its natural biodegradation, lifts humic and fulvic acid levels and delivers the macro, meso and micro elements already present in its composition. Those nutrients are freed over the short and medium term, so deficiencies stay in check, chlorosis is prevented and no limestone residue is left behind.
Gradual Release Across Fast, Medium and Slow Stages
- Programmed release of macro, meso and micro elements
- Progressive nutrition lasting 6 to 8 months
- Nutrients available from the first application
- Raises humic and fulvic acid content in the soil
- No limestone residue
Best Crops and How to Apply It
BIOS Fertile D+ is a good fit for demanding crops such as flowers and first-fruit productions, and it also performs well in mixed soils. For the best results, spread it evenly across the soil before ploughing or milling; used twice a year, it gives solid support to intensive cropping systems.

Because BIOS Fertile D+ releases its nutrients in stages, it can be spread once and still support the crop through the short and medium term, with no limestone residue left in the soil. Choose the powder or pellet format to suit your spreading equipment, and apply it evenly before ploughing or milling for the most even results.
