Fertilisers represent an additive in agriculture indispensable to securing quality and volume in crop production. However, farmers face a crucial dilemma in front of two different categories of fertilisers. Chemical fertilisers have fast nutrient action but are associated with damaging effects on the environment. On the other hand, biofertilisers are environmentally friendly but they have a shorter shelf life, are marked by crop specificity and are costly in management. The EU-funded Bulhnova project proposes an innovative nitrogen-fixing biofertiliser developed by a group of bacteria found in the roots, or rhizosphere soil. The solution comprises Azospirillum brasilense and Pantoea dispersa bacteria and provides an integrated biofertiliser that combines nitrogen, phosphorus and potassium supply. Bulhnova is cost-effective, has multi-nutritional properties and enhances crop quality.
