Bio Energy
Plant microbial biostimulant for more efficient fixation of atmospheric nitrogen — its bacteria fix nitrogen in a form accessible to the plant and promote the biological activity of soils.
Plant microbial biostimulant that increases the amount of available phosphorus in the soil for optimal phosphorus uptake by the crop.
Plant microbial biostimulant that improves potassium assimilation and potassium balance in the soil, and increases resistance to droughts and frost.
Soil
Contains a bacterial complex that promotes seed viability and germination and improves growth and development of the root system.
Promotes soil biological and enzymatic activity and increases the amount of phosphorus and potassium available to plants.
Improves plant response to cold weather, frost, waterlogging or drought by increasing the concentration of proline in plants.
Increases mineralisation of crop residues, enhancing decomposition of lignin and cellulose and the change of vegetal residues into humus.
Plant microbial biostimulant for healthy soil and plants, applied from before sowing right up to flowering.
Foliar
Silicone-based, non-toxic and environmentally friendly penetrating substance (spray adjuvant) designed to enhance the absorption and effectiveness of foliar applications.
