Treatability of oil palm frond and rubber wood chips with urea for the development of slow release fertiliser
Treatability of a material is fundamental in determining how much chemicals or fillers are retained in the material before it can be used for slow release fertiliser. The aim of this study was to investigate the effect of urea retention in oil palm frond and rubber wood chips treated at different ur...
