Lignin linked to slow biodegradability of urea-crosslinked starch in an anaerobic soil environment
For slowing fast solubility and increasing the period of urea's release in soil, urea-crosslinked starch (UcS) was prepared and applied as a slow release fertilizer. The higher environmental biodegradability of UcS is a major drawback for slow release of urea yet it provides an important challe...
