1、Foliar Application of Different Iron Sources Improves Morpho

Foliar application of different iron sources (synthesized nano-iron, chelated iron, and iron sulfate) significantly enhanced the pod yields and its components. Additionally, there is a favorable correlation between the seed’s iron content and biological yield.

2、Application of different foliar iron fertilizers for enhancing the

Here, pot experiments in rice were conducted to characterize the effects of four types of foliar-applied Fe fertilizer (chelated ferrous Fe, ferric Fe, ionic ferrous Fe, and ferric Fe) at three doses (20, 50, and 100 mg L −1) on photosynthetic capacity, antioxidant ability, yield, and Cd accumulation in Cd-contaminated soil.

3、Iron Fertilizers

Iron fertilizers are defined as substances that supply iron, an essential micronutrient for plant growth, to improve bioavailability and enhance plant nutrition, with iron nanofertilizers being a specific type that utilizes nanosized iron particles or composites to increase effectiveness in soil absorption.

The potato (Solanum tuberosum L.) is an important food crop in the alkaline soil area of northwest China. It is abundant in ascorbic acid (vitamin C), which facilitates iron absorption in the body. The large consumption of potato makes it a good food source of iron absorption for human body.

Foliar Application of Different Iron Sources Improves Morpho

This research was implemented on broad bean plants (Vicia faba L. var. major Harz) to examine the impact of three iron sources: nano-iron (FeNPs, T1), iron sulfate (T2), and chelated iron (T3) as a foliar spray on the morphological properties, physiological attributes, and nutritional status of these plants compared to the untreated plants ...

Comparative study of the effectiveness of nano

In this study, four nano-iron materials (Fe nanoparticles (Fe-NPs), Fe3 O 4 -NPs, α-Fe 2 O 3 -NPs and γ-Fe 2 O 3-NPs) were compared with traditional iron fertilizers (FeSO4 and Fe-EDTA). The results showed that the efficiency of traditional iron fertilizers decreased greatly under simulated rainfall conditions due to their poor leaching resistance.

Foliar fertilizers are nutrients applied directly to plant leaves to supply essential elements. Due to their direct absorption through leaves, these fertilizers boast high efficiency and rapidly replenish micronutrients and nutrients. Below are common types of foliar fertilizers and their characteristics:

1. Seaweed Fertilizer: Rich in minerals and trace elements (e.g., seaweed extracts, alginates), seaweed fertilizer effectively supplements iron, enhances growth rates, and improves disease resistance. It also regulates soil pH, improves soil structure, and boosts uptake of other nutrients.

2. Amino Acid Fertilizer: Composed of amino acids like aspartate and glutamate, this fertilizer provides nitrogen, phosphorus, and potassium while strengthening photosynthesis and stress resistance. It is ideal for leguminous crops and fruit trees.

3. Humic Acid Fertilizer: Made from humic acid, it enriches soil fertility and contains organic matter and micronutrients. Suitable for commercial and food crops, it improves soil health and nutrient availability.

4. Microbial Fertilizer: Features beneficial microorganisms (e.g., nitrogen-fixing, phosphorus-solubilizing bacteria) that decompose organic matter, release nutrients, and enhance soil bioactivity. Best for legumes and green manure crops.

5. Composite Fertilizer: Combines multiple nutrients (e.g., seaweed + amino acids or seaweed + humic acid) to provide balanced nutrition, accelerating growth and disease resistance. Widely used for commercial and food crops.

6. Slow-Release Fertilizer: Formulated to gradually release nutrients over time (e.g., seaweed + amino acids + humic acid). Reduces application frequency while sustaining nutrient supply. Suitable for various crops, especially high-value and food crops.

7. Water-Soluble Fertilizer: Dissolves quickly in water (e.g., seaweed + amino acid blends) for rapid nutrient absorption. Enhances growth and resilience in diverse crops, particularly commercial and food varieties.

foliar fertilizers vary widely, each with unique strengths. Selecting the right type depends on crop needs and soil conditions to optimize fertilization outcomes.
