2020 assumptions: Stillage will be spread over up to 80% of the total area. Filtercake mud, boiler ashes and soot will be used in up to 13.34% of the total area, in rates of 10 t (dry) per hectare. The area fertilized exclusively with mineral fertilizers will represent 6.66% of the total area. There will be areas that may be fertilized with stillage and/or filtercake+soot+ashes and/or mineral fertilizers (complementation). General assumptions for calculation: Total area (ha) 30000 Harvested area (ha) 27000 Reforming area (ha) 3000 Normal conditions for reforming areas + seed areas Plant cane area (ha) 2700 It must be the same area of reforming area of the previous year Ratoon area (ha) 24300 It is the difference between the total harvested area and the plant cane area Average productivity (t/ha) 95 It must be, at least, 10 t greater than the current average Harvested cane (t) 2565000
