Demand is increasingly strong for inputs that have a positive impact on the environment, the soil and users, while maintaining optimum efficiency for crops.
At the same time, limiting waste by recycling is becoming a priority.
Competitive advantages
- Long-lasting, effective fertiliser produced from plant residues
- Controlled-release fertiliser with the possibility of modulating the rate of release
- Agronomic tests showing the cultivation of more fruit & sweeter than in untreated soil, and equivalent in soil with the Osmocote fertiliser
Applications
Range of fertilisers for:
- use in greenhouses and for spreading
- in conventional or organic farming
Intellectual property
Patent
Development stage
Validation of the technology in a real environment
Description
The technology consists of a new controlled-release fertiliser made from plant residues.
Sunflower protein concentrate is destructured and plasticised via twin-screw extrusion, together with a source of NPK.
Technical specifications
Function of the constituents and manufacturing stages of the innovative fertiliser:
- Sunflower protein concentrate: contribution of organic nitrogen + matrix
- Source of NPK: urea (mineral nitrogen), feather meal (organic nitrogen), poultry or insect droppings (organic nitrogen)
- Twin-screw extrusion: destructuring/plastification with plant proteins
- Abrasion resistance of 1% to 4% (m/m) for use in greenhouses and for spreading
- Slow, gradual disintegration in water: favours gradual release and modulation of the release rate
