Biochar extract compounds alter germination and growth of crop seed

Positive or negative plant growth effects due to soluble organic biochar compounds are not well understood. Increasing quantities (0 g, 0.5 2.5 and 5 g) of four different biochars were extracted with 0.1 M HCl, which separated marked as W, X, Y, Z. Corn rice seeds treated extract solution. The straw Y Z solutions positively affected corn germination, while the cotton solution negatively it. When differences present, always caused reduction in seed germination. tended increase, wheat decrease, little evident terms Spartina alterniflora on bud root length when compared control. treatments reduced control, especially Organic compounds, e.g., triethyl phosphate, 2,4-bisphenol, present solutions, likely promoted at lower concentrations. Determining presence moieties helped designing for enhanced growth, crop productivity.
