FINAL REPORT

Area 2 (Tawin Gazar, Buyant Sum)
The Area 2 is located 6, 2 km east of Buyant Sum center and was used for vegetables
cultivation in former times. The projected area (Tawin Gazar) has a length of 4550 m and a
width of 1100 m (500.5 m 2 ). Old and hardly visible irrigation channels and natural small river
beds, which are flooded episodically, are passing the whole area. Different pebble fans can be
distinguished in this area as well. The micro relief is very variable with height differences of
up to 1.2 m. The inclination is 0.5 %.
The soil type is an extreme dry Brown Soilwith a high amount of skeleton of coarse pebbles.
The total area is very heterogeneous in the surface coverage, however mostly highly
compacted, that means you have to calculate with extreme slow sickering of water or a high
amount of surface runoff. Areas of Caragana stands seem to be not cultivated anytime. In the
eastern part the soil seems to be developed on a former lake bottom, which means a high
carbonatic compacted underground. Sample No 068 and 069 was an extreme pebble rich
compacted brown soil.
