Implication

Spatial analysis reveals climate-dependent planting thresholds in temperate staple crops, indicating that tropical scheduling depends more heavily on non-climatic factors.

Key Points

Assemble a global dataset of crop planting and harvesting dates for 19 major crops and evaluate the spatial relationships between planting timing and climate variables.
Digitized and georeferenced existing crop planting and harvesting calendar data from six distinct sources for 19 major crops worldwide.
Evaluated spatial correlations between planting dates and 30-year average climatologies of temperature, precipitation, and potential evapotranspiration using CRU CL 2.0 data.
Maize planting in northern mid-latitudes occurs primarily in April and May at daily mean air temperatures of approximately 12–17 °C, though soil moisture often serves as the direct determinant.
Spring wheat is typically planted at cooler temperatures between approximately 8 and 14 °C in temperate regions, whereas winter wheat is planted during September and October.
Tropical maize planting dates and global winter wheat dates display wide variability and low predictability when modeled using baseline temperature data alone.
