Supporting evidence — 7 representative gaps

• Controlled-release phosphorus dynamics of urine-derived struvite for nutrient recovery and circular agriculture in tropical soils (2026) · Scientific Reports · doi

  The higher residual phosphorus availability observed under HU-Struvite suggests reduced rapid phosphorus fixation associated with iron and aluminum oxides, a major limitation to phosphorus-use efficiency in highly weathered soils. Because the experiment was limited to the first 45 days of maize growth under greenhouse conditions, the agronomic performance reported here should be interpreted as representative of the early vegetative stage.

• Optimizing phosphorus management in canola (Brassica napus L.) through integrated soil, foliar, and fertigation applications under greenhouse conditions (2026) · Scientific Reports · doi

  The limited availability of phosphorus in soils and its immobility and fixation in soils restrict biomass production and cause deficiency symptoms. The low phosphorus use efficiency of conventional fertilization methods. The need for sustainable phosphorus management practices in agriculture.

• Cover crop cultivation and incorporation improve phosphorus fertilizer-use efficiency by subsequent wheat crop (2026) · Plant and Soil · doi

  One challenge is the limited understanding of phosphorus-mobilizing mechanisms in plants. Another challenge is the lack of effective methods for quantifying the impact of cover crops on soil phosphorus availability. A technical challenge is the difficulty in measuring phosphorus levels in soil and plant samples.
