Our aim was to derive a model to predict the N mineralization\/immobilization from readily available information on the properties of organic fertilizers in farming practice. On the basis of a literature review, a characterization of organic fertilizers was performed, revealing a large variance in fertilizer properties within the defined categories and subcategories. A partial linear model was derived and used for the prediction of N mineralization\/immobilization based on the type of fertilizer and the carbon (C) to organic nitrogen (Norg) ratio. Depending on the previously defined category, a strong mineralization (e.g., plant- and animal-based commercial fertilizers) or a predominant immobilization (e.g., compost and slurries) was detected. For a total of seven main categories and their subcategories, individual models were developed. This work shows that the mineralization properties of organic fertilizers can be sufficiently predicted through a simple classification into a fertilizer category and through the C to Norg ratio.<\/jats:p>","DOI":"10.3390\/agronomy10091448","type":"journal-article","created":{"date-parts":[[2020,9,23]],"date-time":"2020-09-23T09:28:08Z","timestamp":1600853288000},"page":"1448","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":36,"title":["A Typological Concept to Predict the Nitrogen Release from Organic Fertilizers in Farming Systems"],"prefix":"10.3390","volume":"10","author":[{"given":"Andr\u00e9","family":"Sradnick","sequence":"first","affiliation":[{"name":"Leibniz Institute of Vegetable and Ornamental Crops (IGZ) e.V., Theodor-Echtermeyer-Weg 1, 14979 Gro\u00dfbeeren, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carmen","family":"Feller","sequence":"additional","affiliation":[{"name":"Leibniz Institute of Vegetable and Ornamental Crops (IGZ) e.V., Theodor-Echtermeyer-Weg 1, 14979 Gro\u00dfbeeren, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,9,22]]},"reference":[{"key":"ref_1","first-page":"8","article-title":"Soil food web controls on nitrogen mineralization are influenced by agricultural practices in humid temperate climates","volume":"8","author":"Whalen","year":"2013","journal-title":"CAB Rev.
