Sustainable integrated agricultural management practices - Prospects of a sustainable production of biomass
Establishing Willow on Nutrient-Poor, Marginal Sandy Substrates Employing Tailored Fertilization Strategies
Short Introductive summary
The present study focuses on the establishment of two willow species, Salix viminalis L. and Salix alba L. which are suitable for growing on marginal lands, evaluating their rooting capacity, early establishment success, and initial growth performance. The experimental design compares tailored fertilization strategies based on organic residues and mineral fertilizers. In particular, digestates obtained as a residual product from biogas production are assessed as organic amendments in comparison to mineral NPK fertilizers, applied at rates equivalent to 50, 100 and 200 kg N ha?¹. Fertilization was implemented via strip-till as localized underfoot placement at approximately 20 cm depth. The research is embedded in a broader framework targeting biomass production from fast-growing perennial crops while simultaneously addressing soil rehabilitation, carbon sequestration, and renewable energy value chains. Willow-based SRC systems have been shown to improve soil properties and support microbial activity over time, thereby contributing to ecosystem restoration processes.
