Effect Of Nitrohumic Acid Derived From Low-Rank Coal Of Sarawak On Growth Of Brassica Oleracea Sp.
Humic acid derived from low rank coal of Mukah prepared using alkaline extraction method was referred as nitrohumic acid. Nitrohumic acid was characterized for moisture content, ash content, nitrogen content, total acidity, carboxyl groups and phenolic group. Spectroscopy characterization was conduc...
