Then the values were multiplied by the percentage of cropland per grid. * Gridded maps of P fertilizer application rate based on county-level data (10&11): the grid values were assigned by county-level crop-specific application rate from 1970 to 2021 and 1930 to 1969 respectively. Then the values were multiplied by the percentage of cropland per grid. * Gridded maps of P fertilizer application rate by each crop (12-20), the grid values assigned by county-level crop-specific application rate from 1970 to 2021. The values were not multiplied by the percentage of cropland per grid! File names ************* All files include the unit of values in their names. For consumption, the unit is gram P (g_P). For application rate, the unit is gram P per square meter (g_P_m-2). ************* Crops --------------- crop full name short name 1 corn corn 2 soybean soybean 3 winter wheat WinWht/Wwheat 4 spring wheat SprWht/Swheat 5 cotton cotton 6 sorghum sorghum 6 rice rice 8 barley barley 9 durum wheat DurWht/Dwheat 10 cropland pasture CrpPast 11 Other Crops Others ************* Application timing --------------- Timing full name short name 1 Fall in previous year FL 2 Spring before planting SP 3 At planting AP 4 After planting AF ************* Application method --------------- Method full name short name 1 Non-broadcast NBC 2 Broadcast with incorporation BWI 3 Broadcast withno incorporation BNI
