    Balancing Feed Demand and Energy Supply: Technical Potential of Permanent Grassland Biomass in Poland
    (MDPI, 2025) Borzęcka, Magdalena
    This study presents a comprehensive methodology for assessing the technical potential of hay biomass from permanent grasslands (TUZ) in Poland, aimed at evaluating its energy use possibilities. This research was based on detailed data from the Agency for Restructuring and Modernization of Agriculture (ARiMR) and included both environmentally subsidized and non-subsidized parcels. Using statistical hay yield values adjusted for drought impacts through the Climatic Water Balance (KBW), a realistic estimation of technical hay potential was obtained. Results show a total theoretical hay potential of 15 million tonnes in 2024. The results indicate that the total theoretical hay potential in the country in 2024 amounted to 15 million tons, but its technical potential is reduced to almost zero. The methane productivity of this biomass could generate 3.5 Mt CH4 (at STP) if most of it could not be used for animal feeding purposes. The findings highlight the underutilized energetic potential of grasslands and the critical role of land use policy in unlocking sustainable bioenergy resources. Research into the potential of biomass is important in view of supporting energy independence, sustainable use of agricultural resources and agroecological synergy by combining production, energy and environmental objectives. It should be remembered that biomass potential studies are subject to limitations resulting from the uncertainty of statistical data, variability of climatic and soil conditions and model assumptions, which may affect the accuracy and comparability of the obtained results.

    Priority directions for supporting the bioeconomy in the context of the cap in Poland
    (Instytut Uprawy Nawożenia i Gleboznawstwa - Państwowy Instytut Badawczy w Puławach, 2025) Pudełko, Rafał; Borzęcka, Magdalena; Podleśny, Janusz
    The monograph presents the bioeconomy in the context of agriculture, rural areas, and the challenges arising from climate change and the transition towards sustainable development. It aims to provide a comprehensive overview of the significance of the bioeconomy as a key element of the European Union’s development policies and to identify opportunities for its implementation in Poland, focusing particularly on the agricultural and agrifood sectors. The initial chapters discuss the objectives and importance of the bioeconomy and review strategies for its development in rural areas in selected EU Member States, such as Italy, Spain, Germany and Lithuania. This analysis allows for the identification of good practices and diverse approaches to the use of biological resources for regional development. A crucial point of reference for further consideration are the assumptions and objectives of the European Green Deal, setting the framework for the transformation of food production systems and management of natural resources. The following chapters focus on the role of agriculture in a sustainable bioeconomy and its adaptation to climate change. They present both the currently observed and projected effects of climate change, as well as adaptation strategies used in the European Union and Poland. Particular emphasis is placed on types and categories of adaptation and practical solutions that enable increasing the resilience of agriculture to adverse environmental conditions. A significant part of the monograph is devoted to the analysis of agricultural biomass. This part discusses biomass used for food purposes, covering the production of cereals, legumes, oilseeds, sugar beet, potatoes, fruit and vegetables, as well as modern methods of storage, preparation for marketing and packaging of plant products. A separate chapter is devoted to waste and by-product biomass from the food industry, including both plant and animal products, taking into account the scale of food losses and possibilities for their valorisation. The rest of the monograph presents the possibilities of obtaining and recycling nutrients and organic matter from the agricultural sector, including the use of digestate, compost and biochar. The production of biochar on small farms has been discussed in detail, covering definitions, quality requirements, substrate sources, production methods, and finally its use in agricultural production. The monograph also addresses the legume and high-protein feed production in Poland, analysing their importance in crop rotation, yield potential, production levels and available support systems. These considerations are supplemented by an assessment of national agricultural biomass resources, including by-products, straw, grassland biomass, animal production and fruit growing. The last chapter is devoted to the potential of unused agricultural land and the possibilities of its use for bioeconomy purposes. It presents methods for identifying such areas, assessing the progress of natural succession and directions for its use, supported by a case study. The monograph as a whole is an interdisciplinary study presenting the bioeconomy as a crucial element of the transformation of agriculture and rural areas, combining environmental, economic and social objectives, while at the same time indicating solutions possible for implementing in Polish conditions.
