Kompostering beskriver nedbrytningsprosessen som organisk avfall gjennomgår for å bli til ny jord.

Dette er Kores temaside for forskning på kompost og kompostering. Her har vi samlet både norsk og internasjonal forskning, og gruppert forskningen i ulike temaer som er viktige for dem som forsker på komposteringens prosesser og kvaliteter.

Report from ORGANICS for tomorrow´s food systems – NJF Seminar 495 4th Organic Conference

Organic agriculture has been recognized as a driver towards more sustainable agricultural practises and food systems. However, there is a need for progress to meet tomorrow´s agricultural, environmental and societal challenges, to be vital for public health and wellbeing and to have a major impact on global food systems. Research plays a fundamental role for the next step.

Organic farming enhances soil microbial abundance and activity—A meta-analysis and meta-regression

Population growth and climate change challenge our food and farming systems and provide arguments for an increased intensification of agriculture. A promising option is eco-functional intensification through organic farming, an approach based on using and enhancing internal natural resources and processes to secure and improve agricultural productivity, while minimizing negative environmental impacts.

Sustainable recycling of organic waste resources in the future bioeconomy

| Type artikkel: Forskningsprosjekt

Kategori: Gjødsel, Klima og miljø, Kompost, Matjord

The intended future bioeconomy requires increased utilisation of available bioresources. As part of this, optimal utilisation of nutrients in waste resources as fertiliser in agriculture will be indispensable. However, waste resources are complex materials that are strongly varying in terms of composition, quantity and quality. Therefore, several barriers will have to be overcome to realise efficient nutrient cycling. For example, large amounts of water in many waste resources can result in difficulties related to handling and application as fertiliser, and that transport is costly over large distances. Further, unknown quality of waste resources as fertiliser is often hindering efficient and environmentally friendly use. Waste resources can contain environmental pollutants and pathogenic microorganisms. Especially microplastics have lately received gained focus. Also, acceptance of waste resources as fertiliser by farmers is unknown, and nutrient recycling can lead to environmental problem shifting.

Manure and tillage use in remediation of eroded land and impacts on soil chemical properties

| Type artikkel: Publisert studie

Kategori: Belgvekster, Erosjon, Gjødsel, Grønnsaker, Humus, Kompost, Matjord, Matplanter

Soil loss through wind and water erosion is an ongoing problem in semiarid regions. A thin layer of top soil loss over a hectare of cropland could be corresponding to tons of productive soil loss per hectare. The objectives of this study were to evaluate the influence of beef feedlot manure, tillage and legume grass mixtures on changes in soil quality and nutrient components. The study was initiated in 2006 on an eroded site near Akron, Colorado, on a Norka-Colby very-fine sandy loam (fine-silty, mixed, mesic, Aridic, Argiustolls).
