Fig. 11From: Hydroxyapatite nanoparticles: an alternative to conventional phosphorus fertilizers in acidic culture mediaFertilizing effects of nanoformulations and TSP on wheat growth in acidic soil. This figure shows the effects of different treatments on aboveground weight (a) and spike weight (b) in acidic soil. Lowercase letters indicate statistically significant differences (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
