The availability of P, as a fraction of the measured and mapped contents of N, P and K, is calculated using the formulas proposed by Sattari (Sattari et al. 2014, DOI:10.1016/j.fcr.2013.12.005) and pedotransfer functions (PTFs) from the QUEFTS model (Janssen et al., 1990, https://doi.org/10.1016/0016-7061(90)90021-Z).
