- •
Larger datasets were used to analyze the variation of soil available P and the crop yield response to P application.
- •
The datasets were divided into two groups: grain crops and cash crops.
- •
We analyzed the changes of soil available P in farmland in China from 1990 to 2012.
- •
We analyzed the temporal and spatial variability of soil available P and the crop yield response to P application across the five regions (NE, NC, NW, SE and SW).
