Basic soil productivity (BSP) is the productive capacity of farmland soils with their own physical and chemical properties during a specific crop season under local field management. Improving BSP as an effective way to increase or maintain yield, researching its changes potential driving factors long-term fertilization are crucial for ensuring high stable yields. In this study, yields were simulated using decision support system agrotechnology transfer (DSSAT) model based on three experiments, changing characteristics investigated various treatments in wheat–maize rotation systems 1991–2019. Five included: (1) unfertilized control (CK); (2) balanced mineral (NPK); (3) NPK plus manure (NPKM); (4) dose (1.5NPKM); (5) straw (NPKS). This study found that wheat maize exhibited fluctuating change trend four at Yangling (YL) Zhengzhou (ZZ) sites, while reduction was observed Qiyang (QY) site. Compared CK, NPKM, 1.5NPKM NPKS significantly (p < 0.05) improved YL ZZ sites.

Agricultural land resources are essential for food production, and thus it is vital to examine the spatiotemporal changes in these their impacts on suitability optimize resource allocation. In this study, we investigated spatial evolution of cropland through use change analysis by utilizing four periods data from 1990 2020 black soil region northeast China (BSRNC). Employing niche theory, developed a cultivability evaluation model tailored BSRNC, which was used assess impact patterns over past 30 years suitability. Our key findings as follows: (1) Cropland have generally tended expand with an increase 7.16 × 103 km2 cultivated area northeastward shift center 52.94 km, indicating significant configuration land. (2) The region’s cultivable were substantial, covering 694.06 km2, or 55.78% total area, notable variability, influenced regional climate topography. (3) has slightly improved, shown 0.10 index, but declining trend observed after 2000. provide valuable insights help accurately productivity BSRNC facilitate sustainable conservation soil.

ABSTRACT Crop rotation can help to alleviate land use pressure, prevent soil degradation, and promote sustainable agricultural development. Land in Northeast China has long been overused ensure national food security. Maize–soybean (MSR) is an effective conservation strategy, but its suitability not yet determined China. In this study, we applied optimized MaxEnt model by integrating multiple environmental variables systematically predict the of for maize soybean cultivation, establish MSR function, define specific range priority The obtained significantly improved performance, where suitable areas covered 60.25% 56.88%, respectively, total area Suitability was influenced factors, including climate, topography, soil, hydrology, conditions, particularly gravel content depth, were identified as main factors. Extensive are supporting MSR, highly only account 6.96% area, they primarily located Songnen Plain, most which developed into cropland. scientifically implementing thereby providing crucial support adjusting planting structure optimizing planning

The cultivated land in the black soil of Northeast China (BSNC), due to long-term high-input and high-output utilization, is facing a series challenges such as erosion, compaction, nutrient loss. However, existing quality evaluation (CLQE) lacks regional specificity, making it difficult accurately reflect (CLQ) characteristics across different areas. Therefore, this study proposes comprehensive framework that integrates both functionality degradation risk, establishing an assessment system consisting 18 indicators comprehensively evaluate CLQ BSNC from multiple perspectives. results indicate exhibits declining trend north south, with second- third-grade dominating, accounting for 75.68% total area. overall increases west east, Liaohe Plain Region (LHP) performing best. Low-risk primarily concentrated Songnen (SNP) Western Sandy (WS), covering 38.55% Additionally, finds trade-off between primary productivity function resource utilization efficiency regions, while synergistic relationship observed maintenance functions.
