Organic carbon stocks of desertification monitoring sites

View through CrossRef
18 cuttings and 40 samples of soil organic carbon resources of Gobisumber province were prepared, and morphological, chemical (carbonate CaCO3, reaction medium-pH humus, available potassium K2O) and physical properties (sand, silt, clay) were prepared in the soil laboratory of the Institute of Geography and Geoecology of the Mongolian Academy of Sciences, and analyzed. The reaction environment at the depth of 0-30 cm of the total section was 7.4-9.7% or weakly alkaline to strongly alkaline, and the reaction environment of Ch8 and Ch9 soils was between 6-6.5 or neutral environment. Humus content varied between 1-2.5% of the total soil. Since kastanozems and aridic Kastanozems soils of the dry steppe prevailed, when grouped into these two types, the organic carbon reserves of kastanozems soils ranged from 28.9 to 38 t ha-1, and the reserves of aridicKastanozems soils ranged from 17.7 to 27.6 t ha-1. In the field of desertification, in the experimental area, the reserves were 18.3-24.9 t ha-1 outside the fence, and 12.1-33.8 t ha-1 inside the fence. This result indicated that the level of soil fertility is improving as a result of the rehabilitation of fenced areas.   Цөлжилтийн мониторингийн талбайн органик нүүрстөрөгчийн нөөц (Говьсүмбэр аймгийн жишээн дээр)   Говьсүмбэр аймгийн хөрсний органик нүүрстөрөгчийн нөөцийг мониторинг цэгүүдийн хүрээнд 18 зүсэлт 40 дээж бэлтгэн морфологи болон хими (карбонат CaCO3, урвалын орчин-pH ялзмаг, хөдөлгөөнт кали K2O мөн физик шинж чанарыг (элс, тоос, шаврыг) ШУА-ийн Газарзүй, геоэкологийн хүрээлэнгийн Хөрсний лабораторид шинжилгээнд хамруулсан.

Title: Organic carbon stocks of desertification monitoring sites
Description:
18 cuttings and 40 samples of soil organic carbon resources of Gobisumber province were prepared, and morphological, chemical (carbonate CaCO3, reaction medium-pH humus, available potassium K2O) and physical properties (sand, silt, clay) were prepared in the soil laboratory of the Institute of Geography and Geoecology of the Mongolian Academy of Sciences, and analyzed.
The reaction environment at the depth of 0-30 cm of the total section was 7.
4-9.
7% or weakly alkaline to strongly alkaline, and the reaction environment of Ch8 and Ch9 soils was between 6-6.
5 or neutral environment.
Humus content varied between 1-2.
5% of the total soil.
Since kastanozems and aridic Kastanozems soils of the dry steppe prevailed, when grouped into these two types, the organic carbon reserves of kastanozems soils ranged from 28.
9 to 38 t ha-1, and the reserves of aridicKastanozems soils ranged from 17.
7 to 27.
6 t ha-1.
In the field of desertification, in the experimental area, the reserves were 18.
3-24.
9 t ha-1 outside the fence, and 12.
1-33.
8 t ha-1 inside the fence.
This result indicated that the level of soil fertility is improving as a result of the rehabilitation of fenced areas.
