Abstract

ObjectiveThis study aims to evaluate the effectiveness of Integrated Soil-Crop System Management (ISSM) and provide technical support for sustainable high yield and efficiency in regional agriculture.MethodsThe study compared the effects of no fertilization (Control), conventional farmer practices (FP), high-yield management (HY), and ISSM on maize yield and plant nutrient uptake. Measurements included grain yield, plant biomass, plant nutrient absorption, and soil nutrient content across different management strategies.ResultsOver the 12-year experimental period, a significant decline in grain yield was observed under the Control treatment, with a slight decrease in the FP treatment. In contrast, consistent yield increases were noted for the HY and ISSM treatments. The ISSM approach significantly enhanced the average yield and plant uptake of P and K by 26%, 24%, and 32%, respectively, approaching 98%, 91%, and 85% of the levels achieved in the HY treatment. Furthermore, the average use efficiency of P and K fertilizers in the ISSM treatment exceeded those in the FP treatment by 18.7% and 1.2%, respectively, and those in the HY treatment by 17.4% and 24.8%, respectively. The adoption of ISSM led to a significant increase in total and available P and K content within the 0–20 cm and 20–40 cm soil layers and enhanced the available P and K content across all aggregate size fractions within the 0–20 cm soil layer.ConclusionISSM is capable of achieving long-term high and stable yields for spring maize, enhancing the uptake and utilization of P and K in plants, and bolstering the soil’s capacity to supply these nutrients, thereby fostering the sustainable development of the entire soil-crop system.

前沿 | 推进可持续农业：土壤-作物综合管理在玉米生产中的作用

本研究旨在评估土壤-作物系统综合管理（ISSM）的有效性，并为地区农业的可持续高产高效提供技术支持。研究比较了不施肥（对照组）、常规农作（FP）、高产管理（HY）和土壤-作物系统综合管理对玉米产量和植物养分吸收的影响。在 12 年的实验期间，观察到对照组的谷物产量显著下降，FP 组的谷物产量略有下降。相比之下，HY 和 ISSM 处理的产量持续增加。ISSM 方法大大提高了平均产量，植物对 P 和 K 的吸收率分别提高了 26%、24% 和 32%，接近 HY 处理的 98%、91% 和 85%。此外，在 ISSM 处理中，P 肥和 K 肥的平均利用率分别比 FP 处理高出 18.7% 和 1.2%，比 HY 处理高出 17.4% 和 24.8%。采用 ISSM 后，0-20 厘米和 20-40 厘米土层中的总磷、钾含量和可利用磷、钾含量显著增加，0-20 厘米土层中所有团粒大小的可利用磷、钾含量均有所提高。

期刊介绍： Our natural world is experiencing a state of rapid change unprecedented in the presence of humans. The changes affect virtually all physical, chemical and biological systems on Earth. The interaction of these systems leads to tipping points, feedbacks and amplification of effects. In virtually all cases, the causes of environmental change can be traced to human activity through either direct interventions as a consequence of pollution, or through global warming from greenhouse case emissions. Well-formulated and internationally-relevant policies to mitigate the change, or adapt to the consequences, that will ensure our ability to thrive in the coming decades are badly needed. Without proper understanding of the processes involved, and deep understanding of the likely impacts of bad decisions or inaction, the security of food, water and energy is a risk. Left unchecked shortages of these basic commodities will lead to migration, global geopolitical tension and conflict. This represents the major challenge of our time. We are the first generation to appreciate the problem and we will be judged in future by our ability to determine and take the action necessary. Appropriate knowledge of the condition of our natural world, appreciation of the changes occurring, and predictions of how the future will develop are requisite to the definition and implementation of solutions. Frontiers in Environmental Science publishes research at the cutting edge of knowledge of our natural world and its various intersections with society. It bridges between the identification and measurement of change, comprehension of the processes responsible, and the measures needed to reduce their impact. Its aim is to assist the formulation of policies, by offering sound scientific evidence on environmental science, that will lead to a more inhabitable and sustainable world for the generations to come.
