FINAL REPORT

For the evaluation of the chemical data seethe general comment.
Area 6 (TsagaanKhudag, Khovd sum)
This area has formerly already been agricultural usage and it is planned to recultivate it for
vegetables production. It is located 3 km north of the Bag Center of Ulaanburaa and is called
Tsagaan Khudag. In continuation of old water tubes and recently cultivated fields mostly used
for potato production this area has an extension nearly 1000 x 350 m. The old irrigation
system is clearly visible, what additionally is documented by two distribution points for water.
In the old fields you can find a well developed brown soil, which was well moistured during
the time when taking the samples. The surface is deflated and covered by pebbles; however
the soil type is a silty sand with high capacity of water storage, without being too compact for
water drainage. The projected field has an inclination of 0, 6 %, which reduces the danger of
saltification, because the water can pass the field by natural inclination. On the east side the
field is bordered by an extended area of Caragana with small aeolian sand deposits.
21 samples have been taken (see Table 17).
