Fig. 12From: Hydroxyapatite nanoparticles: an alternative to conventional phosphorus fertilizers in acidic culture mediaFertilizing effects of nanoformulations and TSP on wheat growth in alkaline soil. This figure shows the effects of different treatments on aboveground weight (a) and spike weight (b) in alkaline soil. Lowercase letters indicate statistically significant differences at p < 0.05. Abbreviations: TSP, triple super phosphate; HAP(s), hydroxyapatite nanoparticles in suspension form; HAP(p), hydroxyapatite nanoparticles in powder form; HAP-HA, humic acid-modified hydroxyapatite nanoparticlesBack to article page
