Short summary
In greenhouses, long-term manure application does not always lead to lasting soil carbon. We found that loam and sandy loam store carbon in very different ways. Loam continuously converts particulate carbon into stable forms, while sandy loam relies on short-lived, easily lost carbon. These results indicate that long-term carbon storage depends on soil composition and mineral properties, providing guidance for smarter manure use in sustainable farming.
In greenhouses, long-term manure application does not always lead to lasting soil carbon. We...
