Determination of Significance：

Spectrophotometer/ Microplate reader, adjustable transferpettor, balance, mortar / homogenizer, centrifuge, water-bath, micro glass cuvette/ 96-well plate, sieve (30-50 mesh), ice and distilled water.

Measurement Principle：

Boron and methylimine form brown-yellow complexes under weak acid conditions and have characteristic absorption peaks at 420nm. The content of total boron in soil can be calculated by detecting the wavelength change at 420nm.

Self Provided：

Spectrophotometer/microplate reader, desk centrifuge, water-bath/ constant temperature incubator, adjustable pipette, Muffle furnace, crucible, crucible tongs, micro glass cuvette/96 well flat-bottom plate (Non-polystyrene material), ice and distilled water.
