概括

高度降低了植物的铁可用性. 这项研究发现,与其他铁合物不同,铁-HBED (Fe-HBED) 在性土壤中有效保持铁和的溶解性.

科学领域:

农业化学农业化学
植物营养植物营养
土壤科学土壤科学

背景情况:

铁-EDTA在pH值超过6.5时失去稳定性,导致由于与EDTA的竞争而导致铁缺乏.
土壤中的性可以沉必要的微量营养素,影响作物产量.

研究的目的:

为了研究营养物质沉和微量营养物质与铁合物相互作用,在性增加的情况下.
评估在不同度的二碳酸下,在花豆和玉米中不同铁酸盐 (Fe-EDTA,Fe-DTPA,Fe-HBED) 的有效性.

主要方法:

在法瓦豆和玉米芽中分析植物营养素 (Fe,P,Zn).
使用MINEQL+5.0的规范建模来预测铁的行为.
化研究和扫描电子显微镜与能量分散式X射线光谱学 (SEM-EDX) 分析沉物.

主要成果:

化微量营养素改善了豆芽中铁,和的吸收.
玉米对性表现出敏感性,但在中等性 (5毫米NaHCO3) 时营养反应类似.
在性条件下,Fe-HBED与Fe-EDTA和Fe-DTPA相比,对铁,和具有更高的溶解性.

结论:

从Fe-EDTA中排离铁在高pH下发生,形成不溶性沉物.
在保持性环境中铁和的可用性方面,Fe-HBED比Fe-EDTA和Fe-DTPA更有效.
稳定的铁合物,如Fe-HBED,减少沉,提高作物营养的可用性.

Extraction: Advanced Methods

Metal ions can be separated from one another by complexation with organic ligands–the chelating agent– to form uncharged chelates. Here, the chelating agent must contain hydrophobic groups and behave as a weak acid, losing a proton to bind with the metal. Since most organic ligands used in this process are insoluble or undergo oxidation in the aqueous phase, the chelating agent is initially added to the organic phase and extracted into the aqueous phase. The metal-ligand complex is...

Key Elements for Plant Nutrition

Key Elements for Plant Nutrition

Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...
