Controlled urea release from CMC-based composites: effects of citric acid crosslinking and biochar incorporation

Improving nitrogen (N) use efficiency while reducing environmental losses remains a major challenge in agriculture. Here, we show that a single polymeric matrix based on carboxymethyl cellulose (CMC) can be effectively engineered to control urea release when structurally tailored with citric acid as a crosslinking agen...
