概括

城市生物固体 (MSB) 可以在加拿大农业中取代传统肥料,而不会对土壤细菌群体产生负面影响或增加病原体风险. 这种可持续的做法支持作物生产,并减少对环境的影响.

科学领域:

农业科学农业科学
环境科学环境科学
微生物学微生物学

背景情况:

减少加拿大农业对合成肥料的依赖对于可持续性至关重要.
市政生物固体 (MSB) 是富含营养的有机材料,有可能取代传统肥料.
关于MSB对农业环境中的土壤细菌群落的影响存在知识差距.

研究的目的:

调查市政生物固体 (MSB) 作为肥料补充剂对土壤细菌群落结构和玉米和大豆田中人类病原体的流行的影响.
要确定MSB的应用是否会改变土壤微生物组合或在农业生态系统中引入致病细菌.

主要方法:

实地实验是在两个生长季节 (2021-2022) 的四个北克农业场地进行的.
玉米和大豆的化肥方案被MSB修改,并与标准化肥处理相比较.
用16SrRNA元编码分析了土壤样本,以确定细菌群体的组成.

主要成果:

然而,MSB修正案并没有显著改变土壤细菌群落的结构.
土壤类型和作物特征被确定为细菌社区结构的主要驱动因素.
在研究期间,在MSB处理的土壤中没有发现潜在的人类细菌病原体的丰富证据.

结论:

城市生物固体可以作为田间作物农业中常规肥料的有效替代品.
在短期内,MSB的应用不会破坏土壤细菌社区结构.
在农业生态系统中使用MSB并不比现有的土壤条件对公众健康构成更大的风险,支持它们在可持续农业中的作用.

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.
