概括

施加肥料增加了土壤 (P),但可能导致残留P.有机-无机肥料组合比单独的矿物肥更有效地提高了P的生物可用性和土壤微生物群落.

科学领域:

土壤科学土壤科学
农业化学农业化学
环境科学环境科学

背景情况:

施肥对于作物吸收营养,特别是 (P) 非常重要.
不适当的施肥导致蔬菜田中的过度残留P.
了解不同施肥策略下的土壤动力学是必不可少的.

研究的目的:

调查土壤的动态,以回应无机和有机肥料.
评估受精对土壤P分数和生物可用性的影响.
探索土壤细菌群落在转化中的作用.

主要方法:

在新回收的蔬菜田中进行了为期3年的实地实验.
化学肥料 (CF) 和有机-无机肥 (OF) 联合处理与对照 (CK) 的比较.
分析了土壤Olsen-P,稳定的P比例,不稳定的P分数 (NaOH-P) 和土壤细菌群体结构.

主要成果:

CF和OF都显著增加了土壤Olsen-P,CF显示出更高的增加.
OF增强了中度可变的P (NaOH-P),并促进了二-P的转化为单-P,这表明P的生物可用性得到了改善.
有机-无机受精促进了更连接和更稳定的细菌群体,特定的属被确定为P动员的关键.

结论:

施肥管理显著影响土壤的P分数,营养水平和细菌群落.
组合有机-无机施肥在P生物可用性和土壤微生物健康方面比单纯化学施肥提供了优势.
从化肥中产生的残留P,特别是化学肥料,会给环境带来风险;综合管理对于可持续的蔬菜生产至关重要.

关键词:

(31) P NMR 是一种NMR.细菌网络的相互作用.有机替代物管理管理的分数是的分数.回收的蔬菜田地被回收.

The Phosphorus Cycle

The Phosphorus Cycle

Unlike carbon, water, and nitrogen, phosphorus is not present in the atmosphere as a gas. Instead, most phosphorus in the ecosystem exists as compounds, such as phosphate ions (PO43-), found in soil, water, sediment and rocks. Phosphorus is often a limiting nutrient (i.e., in short supply). Consequently, phosphorus is added to most agricultural fertilizers, which can cause environmental problems related to runoff in aquatic ecosystems.

The Roles of Bacteria and Fungi in Plant Nutrition

The Roles of Bacteria and Fungi in Plant Nutrition

Plants have the impressive ability to create their own food through photosynthesis. However, plants often require assistance from organisms in the soil to acquire the nutrients they need to function correctly. Both bacteria and fungi have evolved symbiotic relationships with plants that help the species to thrive in a wide variety of environments.

Bioremediation

Bioremediation

Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.
