    Manure helps feed the world: Integrated Manure Management demonstrates manure is a valuable resource

    Get PDF
    Overview of Integrated Manure Management Integrated Manure Management is the optimal handling of livestock manure from collection, through storage and treatment up to application (crops and aquaculture). Through this process it is possible to prevent nutrient losses to a large extent under the site-specific circumstances. Healthy soils produce more food and are more resilient to climate change. Manure contains nutrients and organic matter essential for good soil fertility and soil health. Manure is a valuable resource of crop fertilizer, soil amendment and renewable energy. Manure is not a waste; not properly using manure is a waste

    De 'dip' in de tweede snede, hoe zit dat?

    Een veelbesproken verandering in het stikstofbemestingsadvies is de lage bemesting, de 'dip' van de tweede snede. Veldproeven op verschillende locaties en in verschillende jaren tonen aan de nawerking van stikstof na de eerste snede sterk is en dat een lagere bemesting van de tweede snede toch zinvol is

    Local delamination on heavily deformed polymer-metal interfaces:evidence from microscopy

    Get PDF
    In this work the microstructure of interfaces present in heavily bi-axially deformed polymer-coated metal is studied. Cross sections of deformed polymer-coated steel are prepared using several polishing strategies, including the use of focused ion beam, and are imaged using optical microscopy and scanning electron microscopy. We find that the interfaces show significant details right down to the smallest scale observable with the preparation techniques used of about similar to 10 nm. Local delamination events at these deformed interfaces are observed and are found to be preferentially associated with overhanging parts on the interface. Overhanging parts are frequently observed, but only below a certain length-scale on the interfaces that are otherwise found to be self-affine up to a certain correlation length. The smallest detail includes the tail of the size distribution of the overhanging features. Together this suggests that the physical mechanisms determining the formation of critical features for adhesion operate at sub-grain level as well as at grain level
