Sustainable integrated agricultural management practices - Prospects of a sustainable production of biomass
Tailored Fertilization for Sustainable Plant Biomass Production on Marginal Soils
Short Introductive summary
In a circular bioeconomy, the sustainable production and supply of plant biomass is of crucial importance. A particular challenge here is the upgrading of low-yield, nutrient-poor, and non-agricultural land for the cultivation of selected plants for material and/or energy use. To address this challenge, the "Marginal Field Lab" was established in the Rhenish opencast mining area on the edge of the Hambach opencast mine. It aims to investigate the effects of targeted fertilization measures on the growth of selected plants in extremely nutrient-poor, sandy marginal soils. The presentation of the large-scale research project "Marginal Field Lab" and initial results from the plant trials conducted there were introduced at EUBCE 2025. Following the field seasons 2024 and 2025, we present here the evaluation of the fertilizing effects of digestates in comparison to mineral NPK fertilizers in marginal, nutrient-poor sandy substrate at different nutrient application rates. The application rates investigated corresponded to an equivalent 100 and 200 kg nitrogen (N) per hectare (ha) in the form of digestate or mineral NPK fertilizer.
