Accurate diagnosis of plant phosphorus nutritional status is critical for optimizing agricultural practices and enhancing resource efficiency. Existing methods are limited to qualitatively assessing cannot quantitatively estimate the plant’s requirements. Moreover, these time-consuming, making them impractical large-scale application. In this study, we developed an advanced absorption model (Pabs) that integrates nutrition index (PNI) use efficiency (PUE). The PUE, a metric phosphate fertilizer efficiency, was quantified by comparing yields under fertilized unfertilized conditions. Utilizing Agricultural Production Systems Simulator (APSIM) model, simulated maize (Zea mays L.) concentration (P) aboveground biomass (Bio) varying application rates. exhibited robust performance, achieving R2 above 0.95 RMSE below 0.22. Based on APSIM simulations, dilution curve (Pc = 3.17 Bio−0.29, 0.98) established, reflecting trends across growth stages. Furthermore, vegetation indices (VIS) evaluate also showed promising results, with inversion accuracies exceeding 0.70. To validate field sampling conducted in maize-growing regions Changchun. Results demonstrated correct rate 75%, underscoring model’s capacity accurately requirements regional scale. These findings highlight Pabs as reliable tool precision management, offering significant potential optimize fertilization strategies support sustainable systems.

Successive winter wheat (WW) rotations are associated with a substantial yield decline, and the underlying mechanisms remain elusive. An outdoor experiment was set up using sandy loam soil. WW grown in rhizotrons, soil after oilseed rape (KW1), one season of (KW2), three successive seasons (KW4). We applied zymography harvested plants at stem elongation stage to observe changes activity β-glucosidase (BGU) leucine aminopeptidase (LAP), as well glucose (GLU) imaging release patterns rhizosphere WW. Several biochemical microbial properties bulk rotational positions were measured. KW2 KW4 exhibited reduced plant biomass compared KW1. There higher root length density mean diameter lower specific for KW1 KW4. had mineral N concentration carbon (C) nitrogen (N) than KW4, which translated C:N ratio.

Lower dissolved organic C hotspot areas GLU might explain shifts community composition, possibly leading dysbiosis microbes rhizosphere. Soil depth position explained most variance communities.
