Poland Weather Favourable for Spring Crops

02 July 2012

POLAND - Soil moisture has recovered in the west but more rain is needed in some areas. Positive outlook for winter crops in eastern areas and for spring crops across the whole country.

The analysed period (May 20 - June 15) started with high temperatures followed by a cold spell between May 30 and June 6.

The end of the observed period was in the seasonal thermal range. In western areas 1-2 days with maximum temperature above 30°C were recorded. The accumulation of active temperatures (Tbase = 0°C) was seasonal; crop development slightly slowed down towards the end of the period.

After scarce rainfall, mainly in the north-west and the west in May, June started with beneficial and well distributed rainfalls. Within two weeks a slight surplus of cumulated rainfall as compared to the long term average was recorded in most of the country. The exception was north-western Poland, mainly Zachodniopomorskie, here the rainfall deficit reached 40 per cent.

Winter wheat started grain filling in the south and is flowering in the north few days in advance compared to LTA. Winter rapeseed in the south-west is ripening whereas in the other regions it is finishing grain filling and starting ripening.

Water limited storage organs accumulation is above LTA and the last two years. Spring barley is flowering all over the country. Soil moisture has recovered in western areas, which received more rain beneficial for crop yield formation.

Rye is filling grains in most of the country and started ripening in some places in the west and south everywhere in slight advance. The weather conditions were favourable for storage organ accumulation. Grain maize and sugar beet are in vegetative development.

Model outputs would allow to forecast good yield outlook for all crops but yield forecasts for soft wheat and rapeseed have not been increased due to the negative impact of abnormal winter weather conditions for winter crops (except rye). More than 30 per cent of the acreage was re-sown into spring varieties and other crops.(in Kujawsko-Pomorskie, Lodzkie, Wielkopolskie and Lubuskie the percentage even doubled)

Remote sensing indicators (fAPAR) reached LTA values in the first ten-day period of June due to good development of spring crops. Previous values were lower than average because of rather poor growth of winter crops in the regions mentioned above.
