From: Biochar and fulvic acid amendments mitigate negative effects of coastal saline soil and improve crop yields in a three year field trial

Figure 5

Grain yield of each season as influenced by different treatments during the three year trial. CK is control, BC1 is 7.5 t ha−1 biochar, BC2 is 15 t ha−1 biochar, BC3 is 30 t ha−1 biochar, FA is 1.5 t ha−1 fulvic acid. Values are means ± SE (n = 3). For each season, bars within each panel with different letters are significantly different according to LSD at p < 0.05 level. Bars with the same fill color represent the same crop species during the experiment.
