“…This is in line with recent findings by Otinga et al [69] reporting that soil available P enhanced with the application of P fertilizers (TSP) with positive impacts on soil fertility. In addition, application of P fertilizers including mono-calcium P (MCP) and DAP improved nutrients (P and N) uptake of rice [70] . This fertilization could affect positively shoot and root P content generating higher plant biomass (80%) compared to unfertilized plants [71] .…”

“…These findings are consistent with the results of Dobermann et al [54] who revealed that fertilizer P application increases the soluble inorganic P fractions. Another factor for high crop yield could be the higher P application under HNPK that resulted in high crop root density ultimately helping in the greater P uptake and the yield [38,55,56]. This evidence could suggest the maximum P uptake by long-term inorganic additions.…”

Elevated mineral fertilization may change the composition and increase the availability of soil phosphorus (P) in subtropical paddy soils and thus affect long-term plant growth. However, an understanding of the response of soil P fractions to long-term nitrogen, phosphorus and potassium (NPK) additions remains elusive. This study aimed to explore the responses of soil P-fractions and their mobility to different long-term chemical fertilization rates under a double rice cropping system. The rates of nitrogen (N), phosphorus (P), and potassium (K) in the low NPK treatment (LNPK) were 90, 45, and 75 kg ha −1 year −1 , respectively, and in the high NPK treatment (HNPK), they were 180, 90, and 150 kg ha −1 year −1 , respectively. The results showed that the concentrations of soil organic matter (SOM), total P, Olsen P, total N, and mineral N were remarkably increased under HNPK by 17.46%, 162.66%, 721.16%, 104.42%, and 414.46%, respectively, compared with those under control (CT). Compared to the CT P fractions, HNPK increased the labile P fractions (i.e., NaHCO 3 -Pi and NaHCO 3 -Po) by 322.25% and 83.53% and the moderately labile P fractions (i.e., NaOH-Pi, NaOH-Po and HCl. dil. Pi) by 163.54%, 183.78%, and 3167.25% respectively, while the non-labile P was decreased by the HNPK addition. P uptake and grain yield were increased by LNPK and HNPK by 10.02% and 35.20%, respectively, compared with CT. P use efficiency indices were also higher under HNPK than under LNPK. There was a strong positive relationship between grain yield and P use efficiency (R 2 = 0.97). A redundancy analysis (RDA) showed a strong correlation between soil chemical properties and the labile and moderately labile P pools. Structural equation modeling (SEM) revealed that SOM, mineral N, and available P strongly control the labile P pool. In conclusion, NPK additions under the paddy soils significantly influences the soil P fractions. The soil P dynamics Agronomy 2019, 9, 784 2 of 15 and the mechanisms governing the interactions between plants and soil nutrients are clearly explained in this study.

“…MAP could provide readily available P to plants, and contribute indirectly to improved root growth and development because of the beneficial starter effects of MAP ( Chien et al., 2011 ; Gong et al., 2022 ) because MAP is produced from ammonia and phosphoric acid, and phosphate (

) and ammonium (

) are released upon dissolution.

and

ions are macronutrients that enhance root elongation ( Weligama et al., 2008 ; Lu et al., 2019 ). When MAP was applied, shoot biomass and P uptake were higher than when SSP was applied at the same planting density.…”

Complementary effects of phosphorus supply and planting density on maize growth and phosphorus use efficiency

Phosphorus (P) supply and planting density regulate plant growth by altering root morphological traits and soil P dynamics. However, the compensatory effects of P supply and planting density on maize (Zea mays L.) growth and P use efficiency remain unknown. In this study, we conducted pot experiments of approximately 60 days to determine the effect of P supply, i.e., no P (CK), single superphosphate (SSP), and monoammonium phosphate (MAP), and different planting densities (low: two plants per pot; and high: four plants per pot) on maize growth. A similar shoot biomass accumulation was observed at high planting density under CK treatment (91.5 g plot–1) and low planting density under SSP treatment (94.3 g plot–1), with similar trends in P uptake, root morphological traits, and arbuscular mycorrhizal colonization. There was no significant difference in shoot biomass between high planting density under SSP (107.3 g plot–1) and low planting density under MAP (105.2 g plot–1); the corresponding P uptake, root growth, and P fraction in the soil showed the same trend. These results suggest that improved P supply could compensate for the limitations of low planting density by regulating the interaction between root morphological traits and soil P dynamics. Furthermore, under the same P supply, the limitations of low planting density could be compensated for by substituting MAP for SSP. Our results indicate that maize growth and P use efficiency could be improved by harnessing the compensatory effects of P supply and planting density to alter root plasticity and soil P dynamics.
