Due to the cold winter weather, this monitoring season (January to April 2022) was ahead of crop sown in the northeast region of China. CropWatch Agroclimatic Indicators (CWAIs) show that the precipitation greatly deviated from the average level. The total precipitation increased by 16%. It was above average level in mid-March and late-March. The photosynthetically active radiation was below average (RADPAR - 3%) and the temperatures were above average (TEMP +0.7°C).  Altogether, the potential biomass was 15% above the fifteen-year average level.  

Overall, higher precipitation and warmer temperatures are beneficial to the spring sowing in the northeast region of China. However, sowing dates in some low-lying areas in the region were delayed about a week due to waterlogging caused by above average rainfall. Warmer temperatures in May will facilitate the germination and good establishment of the summer crops.
