Bioenergy Wild Plant Common Tansy (Tanacetum vulgare L.) Grown on Marginal Sandy Soil - Learnings from a Pot Experiment

Short Introductive summary

The cultivation of perennial flowering wild plants like common tansy (Tanacetum vulgare L.) seems promising for more biodiversity-friendly biomass production in Central Europe. However, it is still unclear which types of marginal agricultural land would be suitable for low-risk indirect land use change production of biomass from common tansy. This study aimed to gain initial insights into the suitability of common tansy for sandy sites by means of a 6-L pot experiment using three substrate types: (i) topsoil (Luvisol) from a site near the University of Hohenheim (control), (ii) a mixture of 50:50weight(wt)% pure sand and topsoil (M1), and (iii) a mixture of 83.4:16.6wt% pure sand and topsoil (M2) (n = 5). Both above- and belowground dry matter were determined. Common tansy yielded more than half the stem dry matter in the M1 treatment compared to the control, despite significantly less nutrient availability in the sandy soil. It is recommended to carry out field trials with common tansy on marginal sandy soils under different climatic conditions and to compensate soil-specific nutrient deficiencies with organic fertilizers such as digestate from biogas production and solid manure.
