Coated fertilizer
Coated fertilizer wherein the fertilizer and animal feed comprises particles coated with a biomass composition comprising 5-35 wt. % solid biomass particles with a D 50 between 0 and 250 μm and a D 90 of less than 400 μm and 95-65 wt. % oil, a biomass composition wherein the biomass composition comprises solid biomass particles with a D 50 between 0 and 250 μm and a D 30 of less than 400 μm and a process for the production of a biomass composition wherein a biomass composition comprising solid particles having a D 50 between 100 and 1000 μm is filtrated and the residue is grinded until the solid particles have a D 50 between 0 and 250 μm and a D 90 of less than 400 μm.
