Description: Das Projekt "SP 1.4 Evaluation of nutrient and pollutant cycles of livestock production systems and manure management systems in the North China Plain" wird vom Umweltbundesamt gefördert und von Universität Hohenheim, Institut für Agrartechnik, Fachgebiet Verfahrenstechnik der Tierhaltungssysteme (440b) durchgeführt. The increasing specialization and intensification of the agricultural food production in the North China Plain is leading to restrictions in nutrients and production cycles at farm and regional levels. As a result, livestock production in the North China Plain is entailing serious environmental negative impacts related to manure surpluses and recycling of nutrients, mainly leading to problems associated with water, soil and air pollution. On the other side higher nutrient demands in the local crops is leading to the purchase of chemical or mineral fertilizers when local or on-farm nutrients are not available. Therefore, the efficient use of organic fertilizers not only depends on their availability in the farms, but also on their nutritional composition. Likewise, soil nutrient requirements and plant physiological needs have to be taken into consideration. Indeed, the closer the nutrient cycles and the lower the environmental negative impacts and farm losses are, the greater the chances for a more sustainable resource use in the North China Plain. In the context of the IRTG, aspects of livestock farming in production systems in terms of widely closed nutrients cycles will be integrated. The material flows in different animal husbandry systems will be analysed and the environmental impacts dependent on livestock farming techniques, farms operability and their respective management will be investigated. The applicability and effectiveness of the technical and organizational measures for the reduction of material losses and, the environmental burdens caused by livestock and manure mismanagement in the North China Plain will be reviewed. The benefits and profits for the local cropping systems as result of the application of organic fertilizers originated from livestock farming will be both, ecologically and economically, evaluated as an alternative to replace the use of mineral fertilizers.
