Quantifying the role of soil in local precipitation redistribution to vegetation growth

Precipitation is the primary source of water available to vegetation. Although many studies have explored the spatially heterogeneous relationship between vegetation and precipitation, it remains unknown why different precipitation levels lead to comparable vegetation growth and the same precipitati...
