Ukraine. Ice crust in the fields becoming more compact

30.01.2017

Precipitation in the form of snow was seen in most of Ukrainian regions from January 21-29. Precipitation rates varied depending on the region and ranged within 33-77% of the norm (4-10 mm). Snow depth ranged within 11-25 cm, in some parts of the western, southern, central regions, in Kyiv and Zhytomyr regions they ranged within 1-8 cm. In most parts of Odessa, Mykolaiv, Kherson regions and some parts of Zaporizhia and Donetsk regions there was no snow in the fields, UkrAgroConsult reports.

The depth of soil freezing was 10-30 cm, and in some fields of the western, northern and southern regions it was just 2-10 cm. The minimum soil temperature at the depth of winter crops tillering node dropped to 2-7°C below zero, which was significantly above the critical freezing temperature.

In isolated fields in Sumy and Kharkiv regions, 4-28 mm-thick ice crust has been persisting for over 40 days in a row. It covers 40 to 60% of the field’s area. In eastern parts of Kherson region, 4-10 mm-thick ice crust has been seen for over 10 days in a row, covering up to 70% of the field. The formation of 3-28 mm-thick ice crust was also spotted in isolated fields in Kyiv, Cherkasy, Chernihiv, Kherson, Kharkiv and Zaporizhia regions, covering 20 to 90% of the field’s area. Noteworthy, that ice crust is becoming more compact due to alternation between freezing and thawing temperatures. 

According to the Land Farming Research Institute of the National Academy of Agricultural Sciences, the sugar content in winter crops’ tillering nodes equals 15-17%. The results of plant growing tests indicate the following survival rates of winter cereals: winter wheat – 83-92% depending on the variety and predecessor, winter rye – 93-96%, winter triticale – 90-95%.
