Summary
Ppt præsentation formidler viden og metoder fra OUTFIT projektet til at forbedre fastholdelse og håndtering af høj N belastning i udendørs grisefarefolde, dels ved brug af træplantninger i folde og dels via placering af fodertrug og vand på den ene side og hytten på den anden side af træerne, som udjævner N belastningen over hele folden. Endelig vises viden og eksempler på hvordan tilførsel og indarbejdning af pileflis til jord med høj N belastning via mikrobiel immobilisering af N kan bidrage til at fastholde N midlertidig og derved reducere udvaskningstab. Der indddrages resultater fra både kontrollerede forsøg samt markforsøg i grisefolde. Selv store mængder N kan bindes relativt hurtigt både sommer og vinter.
Summary translation
Ppt presentation conveys knowledge and methods from the OUTFIT project to improve retention and management of high N load in outdoor pig pens, partly by using tree plantings in pens and partly by placing feed troughs and water on one side and the hut on the other side of trees, which evens out the N load over the entire pen. Finally, knowledge and examples are shown of how the addition and incorporation of willow chips into soil with high N load via microbial immobilization of N can contribute to retaining N temporarily and thereby reducing leaching losses. Results from both controlled trials and field trials in pig pens are included. Even large amounts of N can be bound relatively quickly in both summer and winter.
