Agrometeorological bulletins
The weather in autumn was warm and hummed. In August in September the registered amount of precipitations constituted from 1 to 2,5 monthly norm, contributing to the accumulation of soil moisture. At the beginning of optimal sowing period (first half of September) the plant-available soil moisture in arable layer was 20-40 mm or 125-200 % from norm. Such conditions were favorable for sowing, sprouting and further development of winter crops.
The majority of farmers began the sowing of winter crops on 22-28 September. The others began the sowing in October and November that is 1 month later than the optimal period. The end of vegetation period was noticed on 20-21 November, which is close to the usual terms. On 57 % of plots monitored by specialists of the State Hydrometeorological Service were the sowing was carried out in optimal terms, at the end of vegetation period plants were well-sprouted with 2-3 stems, the density of plants on 1 m2 was 325-495. The sufficient plant-available soil moisture contributed to additional development of roots. These plants will survive in winter.
On 43 % of monitored plots were the planting was carried out latter than the optimal dates, the plants were in the coming up period with three leaves. On these plots plants are not very well developed as they did not reach the bushing out and have small quantity of protection substances. During winter these plants may be damaged by low temperatures.
Decade agrometeorological bulletinis the main periodical informative paper highlighting agrometeorological conditions for growth of the major crops and field works carrying out, expected conditions and crops yield. The bulletin contains meteorological and agrometeorological data on observations from 17 meteorological stations and 20 agrometeorological posts.
The bulletin includes 3 Chapters:
- Meteorological parameters (description of weather conditions and their quantitative characteristic).
- Agrometeorological parameters (description of the growth and cultivation of crops, analysis of state).
- Meteorological conditions in tables (average air temperature, deviation from the norm, minimum and maximum air temperature, minimum soil temperature, precipitation amount for a decade, amount of precipitation during vegetation period, precipitation amount since the beginning of the year, snow cover depth, relative air humidity, available soil moisture and etc.).
Products:
Bulletins of weather impact on agricultural crops, field works carrying out during vegetation period.
