  2. Development of company • Established 1995 • Ownedbyprivatepersons • Begun with aerialspreading of fertilizers, trials with ash 1995 ->, in practicalscale 2000->

  3. Matovaara Valtimo Ashfertilizedarea About 5t/ha Nonfertilizedarea Ashfertilized and thinnedarea

  4. Distancesin Finland Ahonkylän tuhkan hankinta Viitasaaren tuhkan hankinta

  5. Logisticts to forest • Peatlands • Mineralsoils is underdevelopment (with urea) • Logistics • Helicopters • Loadingequipment • 1400kg sacks • Micronutrientfertilizer BT-300 • Tractors • As loosegranulatedash • Liming in environmentalcatastrophes and spreading of chemicalfertilizers

  6. Growth in Peatland Additionalincrement0,5-8 m3 ha-1 a-1 -normally 2-4 m3 ha-1 a-1 -duration of effectover 20v (Growth in Ruukki – FFRI experiment, 4t DW/ha) (Metla, Moilanen)

  7. Frost insulation • Diluteashes, whennotsuitable to fertilizeruse • Non-hazardous to environment • As granulated – solubility is lower • Easy to store and construct • Good as insulation • Even 1m thinnerstructure of road • Bearingabout as coarsesand / moraine • Lowerneed for gravel • Ashgravel vs. ordinary
