Economical stimulation of inoculation by mycorrhiza

Economical stimulation of inoculation by mycorrhiza of short-rotation willow grown for energy (per 1 ha)


Operations and effects

Without mycorrhization

With mycorrhization

Establishment of plantation

5000 PLN

5000 + 2500 = 7500 PLN

Annual biomass yield

10 Mg

13 Mg

Total yield during 25 years of plantation lifespan

250 Mg

325 Mg or even 625 Mg

Energy value of total yield

250 × 9 GJ = 2250 GJ

325 × 10* GJ = 3250 GJ

Market value of yield

2250 GJ × 20** PLN = 45000

3250 GJ × 20 PLN = 65000

Income after deduction of establishing cost

45000 – 5000 = 40000

65000 – 7500 = 57500

Annual income of mycorrhization

(57500 – 40000)/25 = 700 or max. 1600 PLN
