415 SOIL ORGANIC MATTER - LOSS ON IGNITION METHOD
By Special Request
Organic Matter by measurement of the amount of organic matter lost on sample ignition.
Summary: This method quantifies the amount of organic matter that is lost when sample is ignited at 550oC in a controlled muffle furnace overnight. This method is used on samples such as soil, compost and manure samples with organic matter content greater than approximately 17%. The method has a detection limit of 0.1 % and is generally reproducible within 10%.
