Agronomic properties and characterization of rice husk and wood biochars and their effect on the growth of water spinach in a field test

This study compared the agronomic properties of rice husk biochar (RHB) and wood biochar (WB) and investigated their effect on the growth rate of water spinach in a field experiment. Each biochar type was tested at 5 different rates of 4.0, 3.0, 2.0, 1.0 and 0.5 kg m3, respectively. The results deta...
