Economic aspects of willow growing in Sweden Hkan Rosenqvist, SLU Sweden Thanks to different EU projects, SLF and Vrmeforsk for funding Important economic variables in the decision-making process Profitability Utilization of existing resources and its alternative value
Risk spreading aspects What should the payment for biofuels from energy crops be from the farmers point of view? Farmers need compensation for: Costs for growing the crop Costs for land Payment for new crop and risk compensation Risk and risk reduction Examples of risk reduction in energy crop cultivation Increased knowledge Cultivation technology Subsidies

High costs with small area of willow Crops for today or the future? Different cost reduction potential for different crops Today's large crops have the lowest costcutting potential There is knowledge and infrastructure for today's crops such as cereals and rapeseed Plant breeding, technology and organizational development can reduce future costs.

(New subject in presentation) Willow in Sweden 2016 Willow in Sweden is concentrated to different regions. Most of the willows are located around the lake Mlaren close to Stockholm. Srskilt om Salix 19 Klla: Jordbruksverket Important factors in Sweden for willow planting Set-a-side land
Subsidies for planting Environmental taxes Forest residues has created a wood fuel market in Sweden Chips from forest residues can delivered all year around Farmers motives for planting Salix. In summary, they were: changing the workload on the farm good income from sale of chips subsidies and expected policies land more suitable for Salix than for cereals Influence on Salix activity from certain farm characteristics positive influence
negative influence Farm Size Pasture Forest land Tenancy Lease to others Owner very young Owner age 50-65 or very old Institutional owner Animal husbandry The characteristics of farmers, who regret their Salix plantation, compared to others, are more renting out of land more set-aside land more forest land
more often work outside the farm Farmers, who reduce their Salix plantation, have these characteristics compared with other farmers: less land more forest land more often work outside the farm less hours work on the farm less use of advice Soils for willow plantation Type of land Percent of farmers Poorer land than avearage 59 Better land than avearage 12

sales and cultivation Sludge is used as a way to increase the profitability Reasons for dissatisfaction Have not harvested the year they wanted. Low harvest net income Difficult to sell salix Organization around harvest is sometime poor. Selling of chips and organizational issues appear to be a major problem for salix cultivars than biology and harvesting technology Engage important Satisfied growers seem to engage more in their cultivation than dissatisfied growers Important to create engagement to growers Salix meetings have increased engagement with growers Many salix growers seem to feel unsure about their crops.
There are a large number of farmers who do not like Salix and not grow Salix. Arguments from this group are: Ugly Destroy drainage Difficult to sell salix Failure to grow energy when food is needed in the world Problems to restore the soil to food crops Knowledge of Salix is often relatively low in non-salix farming farmers. Seems that salix is not a "status crop" to grow. Collaborate with local driving forces is important There is a need for a driving entrepreneurs for things to happen One way to increase Salix area is to collaborate with
and focus on actions in areas where there are driving Salix people. If there is no local support, it is difficult to start with Salix. There are conflicts between different Salix contractors, which maybe hold back cooperation. Questions to think about! How do we work to get increased cultivation of Salix and other energy crops where there are proper economic conditions? How are the right conditions for profitable Salix cultivation or other energy crops created?

Briketting of various feedstock Take care of sludge or wastewater Feed pigs in SRC (New subject in presentation) Waste water irrigation in willow Photo WW Some of the most important conclusions about waste water irrigation are (1) Saved costs in treatment works is much more important than saved costs and higher yield in the willow plantation. Its important to find right treatment works which have high costs in traditional treatment
and low costs for vegetation filter. Some of the most important conclusions about waste water irrigation are (2) Pumps, ponds and pipes to field are higher costs than the irrigation equipment in field. Fixed costs are higher than variable costs. Positive factors to keep costs per kg N and P on a low level are High N and P applications per hectare per year. Long irrigation session. High N and P concentration in the wastewater. Short distance between treatment works and the vegetation filter. Large area of willows.

Good conditions for waste water irrigation when: Need for new investment in treatmentwork Short distance between treatmentwork and willow field. When it not need ponds for storage the water during wintertime. Right entrepreneurs, right people at treatmentwork and right people at the municipality Some of the most important conclusions about waste water irrigation are Saved costs in treatment works is much more important than saved costs and higher yield in the willow plantation.
Its important to find right treatment works which have high costs in traditional treatment and low costs for vegetation filter. Pumps, ponds and pipes to field are higher costs than the irrigation equipment in field. Fixed costs are higher than variable costs. Positive factors to keep costs per kg N on a low level are High N-applications per hectare per year. High N-concentration in the wastewater. Long irrigation session. Short distance between treatment works and the vegetation filter. Large area of willows.
Costs for wastewater irrigation Investment for irrigation about 5 000 Euro per hectare with 10 hectares irrigation. Operation costs about 6 Euro per 100 cubicmetre water Rosenqvists own willow SRC field Agricultural soil, 110 ha Good soil: 85 ha Less good soil: 25 ha Forest: 100 ha Willow SRC: 6 ha Willow on the worst part Planted 1994 Older clones with
