Phosphorus
Explanation:
Phosphate rocks can be very inefficient P sources in soils with a pH > 6.0 (Fardeau et al. 1998) so that the rate of P release is insufficient for optimal plant growth.
Organic farmers are prohibited from using soluble mineral P fertilizers according to EU regulations (European Union 2007, 2008).
