METHOD OF MANUFACTURING STANDARD SAMPLE OF LOWLAND PEAT COMPOSITION Russian patent published in 2013 - IPC G01N33/24 C10F5/00 

FIELD: biotechnology.

SUBSTANCE: method of manufacturing of a standard sample of lowland peat is proposed, including the selection of material in natural conditions, drying and grinding, as well as the averaging. On a representative field according to the geological exploration a site is chosen with lowland peat deposit of homogeneous botanical composition, degree of decomposition and ash content, and in this area at depth, except for the upper anthropogenic layer from the surface of 0.2 m, a sample is taken with sample-taking borer with multiple drilling to the same depth (0.5 to 1.0 m) to obtain a sample of the total mass of 200 kg. Then certification of peat is carried out for the content of agrochemical parameters: mass fraction of moisture, ash content, pH, hydrolytic acidity, total nitrogen, total phosphorus, total potassium, mobile form of iron, mobile form of phosphorus, mobile form of potassium, mass fraction of chlorine, exchangeable calcium and exchangeable magnesium.

EFFECT: invention enables to improve the accuracy of the analysis of peat material.
