Crops in Germany generally showed above average condition over the reporting period, which covered the late stages of sugar beets (October harvest) and early vegetative stages of winter wheat and winter barley. The CropWatch agroclimatic indicators show that for the country as a whole, total precipitation (as measured by the RAIN indicator) was 33% above average, temperature was above average (TEMP, 1.2°C), and radiation significantly below average (RADPAR, -15%). Negative rainfall departures occurred mostly from October to early November and above average rainfall occurred throughout the country after early November. With favorable moisture and suitable temperature, the biomass production potential (BIOMSS) is expected to increase by 14% nationwide compared to the five-year average, even if below average sunshine may reduce expectations.
As shown in the national crop condition development graph and the NDVI profiles, the abundant rain delayed field operations. The VCIx in Germany during this monitoring period was 0.96. The snow has probably protected crops from cold weather and will continue to provide soil moisture. The outlook of winter crops is above average.
Regional analysis
Based on cropping systems, climatic zones, and topographic conditions, six sub-national agro-ecological regions are adopted for Germany. They include, listed with their identification numbers: (58) Wheat zone of Schleswig-Holstein and the Baltic coast, (59) Mixed wheat and sugarbeets zone of the north-west, (60) Central wheat zone of Saxony and Thuringia, (61) Sparse crop area of the east-German lake and Heathland, (62) Western sparse crop area of the Rhenish massif, and (63) Bavarian Plateau. The numbers identify the areas on the maps.
Schleswig-Holstein and the Baltic coast is the major winter wheat zone of Germany. The CropWatch agroclimatic indicator RAIN was well above average (+46%) with warm weather (TEMP, +1.2°C) and radiation significantly below average (RADPAR, -13%). With sufficient precipitation and suitable temperature, biomass (BIOMSS) in this zone is expected to increase by 16% compared to the five-year average. Due to two snow storms NDVI started dropping from December. The area has a high CALF (100%) as well as a favorable VCIx (0.95), indicating high cropped area and favorable crop prospects.
Wheat and sugarbeets are major crops in the Mixed wheat and sugarbeets zone of the north-west. The CropWatch agroclimatic indicators show that abundant RAIN (37% above average) and warm weather (TEMP, +1.1°C) resulted in favorable crop condition for both crops. Biomass (BIOMSS) in this zone is expected to increase by 11% compared to the five-year average. It is conjectured that snow has protected crops from cold weather and will continue to provide sufficient soil moisture. Therefore, crop condition for the region is good according to the high VCIx (0.96).
Central wheat zone of Saxony and Thuringia are another major winter wheat zone; it received about 26% above average rainfall and experienced warm weather condition (TEMP, +1.5°C). Due to favourable weather, the biomass potential (BIOMSS indicator) increased by 19% above average. The VCIx of 0.94 for this region also shows favorable crop prospects.
The sparse crop area of the east-German lake and Heathland district, and western sparse crop area of the Rhenish massif experienced very wet weather conditions, with RAIN above average (+32% and +37%, respectively), warm weather condition (TEMP, +1.7°C and +1.1°C), and very poor radiation (RADPAR, -17% and -18%). BIOMSS was up by 22% and 11% respectively with favorable moisture and temperature, while CALF was at 100% for both. Favorable crop condition was recorded with high VCIx values of 0.96 for the eastern and 0.97 for the western areas, respectively.
