As one important part of soil, the organic matter plays a key role in forming the soil structure and improving the quality of soil. The determination of SOM can provide many fundamental information of soil. Development of accurate, precise and fast analytical method for deter-mining SOM has ...
THE DICHROMATE-WET COMBUSTION DETERMINATION OF SOIL ORGANIC MATTER INVOLVES A TITRATION OF THE EXCESSIVE DICHROMATE. A POTENTIOMETRIC TITRATION IS PROPOSED. THIS MODIFICATION ENABLES A FAST AND ACCURATE END POINT DETERMINATION. MOREOVER, THE METHOD CAN BE EASILY ADAPTED FOR AUTOMATIC TITRATIONS.关键词:...
soil testingdry ashingA simple ashing procedure for routine determination of soil organic matter is described. Two hundred fifteen soils from 19 states and Canada were ashed at 500掳 C and the percent weight loss plotted against the percent organic matter determined by WalkleyBlack titration. The ...
