Abstract

Impacts of soil constraints limiting yields often depends on climate. In years with adequate rainfall, only small impacts of soil constraints are expected. But in dry years, soil constraints can limit plant water uptake and trigger spatial variation in crop growth. In wet years, waterlogging-related constraints can play an important role in the spatial variation of crop growth. We used remote sensing data in Australia’s Northern grain-growing region (from Landsat, average NDVI over periods of high biomass) to investigate the relationship between climate and constraints. The correlations between constraints and the average NDVI in different rainfall years were analyzed. The results showed that the average NDVI was most significantly correlated with constraints in wet years. Possible explanations are that waterlogging associated with sodicity severely affected plant growth in wet years or that the imagery or rainfall data used were not representative of soil constraint impacts and their dependence on climate.
