Summary

Abstract The potential shortage of mineral phosphorus (P) sources and the shift towards a circular economy motivates the introduction of new forms of P fertilizers in agriculture. However, the solubility of P in new fertilizers as well as their availability to plants may be low. In this experiment, we incubated an agricultural soil poor in P (28 mg P 2 O 5 kg −1 ) for 63 days in the presence of a range of organic and inorganic poorly soluble P forms commonly found in new fertilizers: hydroxyapatite (P‐Ca), iron phosphate (P‐Fe), phytic acid (P‐Org) and a combination of P‐Ca and P‐Org (P‐Mix). Cellulose and potassium nitrate (KNO 3 ) were added to stimulate microbial activity at the beginning of the incubation. We included a positive control with triple superphosphate (TSP) and negative con
