China is a largely agricultural country, while the drought climate in northern of more and severe, which influences on agriculture production seriously. The over-exploitation groundwater critical issue low plains Hebei Province. To address this challenge, government has implemented winter fallow rain-fed crop planting policies. In alignment with these policies ensure sustainable utilization protection cultivated land, study conducted long-term field experiments using three green manure foxtail millet rotation models at Shenzhou District experimental base, Hengshui City, Thefoxtail yield, soil bacterial community characteristicsc, physicochemical properties were analyzed to identify an optimal model for promoting development. results revealed that manure-foxtail significantly increased yield compared millet-rallow rotation. millet–Triticum secale achieved highest increase, 12.47% average improvement thousand-seed weight 2021 2022 millet-fallow This also led largest increase available phosphorus content, rose by 46.16 37.56% 2022, respectively. Furthermore, diversity richness rhizosphere under model. Beneficial genera, including those Phyla Bacteroidetes Proteobacteria, abundant, relative abundance Acidobacteria was lowest. Correlation analysis showed organic matter, phosphorus, positively correlated multiple genera Proteobacteria but negatively . conclusion, millet– Triticum effectively improved environment supported stable, high yields. These findings provide theoretical basis advancing strategies offer technical support

Adopting an optimal cropping regime is crucial for sustainable soil use. However, how different regimes impact phosphorus (P) availability and the underlying mechanism remain unclear. Here, a 10-year field experiment was performed to examine influence of regimes, including maize–soybean rotation (MSR), continuous maize (CMC), farmland fallow (FALL), under unfertilized fertilized conditions in Northeast China. The P forms were analyzed using chemical fractionation solution phosphorus-31 nuclear magnetic resonance. Compared FALL, total contents significantly lower MSR CMC systems. Moreover, higher than those CMC. Correlation analysis showed that there significant positive correlations between contents. Redundancy revealed organic carbon (SOC) as most factor influencing P. Structural equation modeling demonstrated direct impacts SOC, nitrogen, phosphorus, Olsen on phosphatase activity, which exhibited availability. In summary, effective promoting accumulation this region.
