1、The role of zinc fertilization and its interaction with nitrogen and
Not only can the nitrogen (N) and phosphorus (P) uptake be limited, but that of zinc (Zn) can also be affected. Moreover, the application of N and P at early growth stages can result in an enhancement of maize growth.
2、Reactions of fertilizer zinc in soil and their effect on Zn availability
The time to fully dissolve a sparingly soluble, granular or banded Zn fertilizer depends on fertilizer properties (granule size, Zn content, chemical form) and on soil properties (soil pH)
3、Impact of physical and melting mixing of zinc and urea on maize yield
In contrast, the physically mixed fertilizer did not significantly affect fertilizer residue other than in CK.
4、Zinc for crop production
A phosphorus-induced zinc deficiency is a concern and may occur only if very high rates of phosphate fertilizer (more than 200 lb P2O5/acre) are used and the soil test for zinc is in the range between Low and Very Low.
5、Zinc in ammoniated phosphate fertilizers: Solid‐phase speciation
We hypothesized that the availability of Zn in the fertilizer to plants is related to its speciation in the fertilizer. We evaluated a range of ammonium phosphate fertilizers using X-ray absorption near-edge structure and assessed the water-solubility of Zn in the formulations.
Zinc Fertilizers
Insoluble ZnNH 4 PO 4 compounds form in ammonium phosphate fertilizers; these reaction products are not very available for crops, especially on sandy, neutral to alkaline soils under dry conditions.
Zinc Fertilizers
Chelated Zn is not readily taken up by plant roots but the enhanced uptake of Zn observed in studies is probably due to enhanced diffusion of Zn to the roots (Zhao et al., 2015). An important characteristic of chelating agents is their capacity to form stable bonds with metals.

Zinc (Zn) deficiency affects 17% of the world’s population, particularly those consuming large cereal grains with low Zn concentration and poor bioavailability.

锌与磷肥不同混合方式对玉米产量及磷、锌利用的影响
A maize pot experiment was carried out with 8 treatments, including the application of the above 4 kinds of zinc-containing phosphate fertilizers (P+Zn0.5, P+Zn5, PZn0.5 and PZn5), common phosphate fertilizer (P) and sulfate heptahydrate (Zn0.5、Zn5), with no fertilization as the control (CK).
Zinc fertilizer, typically referring to fertilizers with zinc as the primary nutrient, is widely used in agricultural production to supplement plants' zinc absorption, promoting growth and enhancing disease resistance. some users may notice that zinc fertilizer does not undergo chemical changes during heating or melting, unlike certain other fertilizers. This observation raises curiosity and confusion about the characteristics of zinc fertilizer. The following sections will explain the reasons behind this phenomenon in detail.
1. Chemical Properties of Zinc Fertilizer
First, it is essential to understand that zinc is a metallic element. At room temperature, zinc exists as a solid with a metallic luster, high hardness, and strong corrosion resistance. From a chemical perspective, zinc fertilizer itself does not possess properties that facilitate easy melting.
2. Physical State of Zinc Fertilizer
Zinc fertilizer is typically sold in powdered or granular forms rather than liquid or solid blocks. This physical state determines that it will not melt under normal conditions. If zinc fertilizer were liquid or solid, heating it to a certain temperature would gradually transform it into zinc compounds (e.g., zinc oxide) rather than causing it to melt completely into elemental zinc.
3. Melting Point of Zinc
The melting point of zinc is approximately 419°C (800°F). This means that zinc fertilizer will begin to melt only when heated to this temperature. this process requires time and does not occur instantly. Additionally, other components in zinc fertilizer (such as nitrogen, phosphorus, or potassium) can further influence its melting point.
4. Solubility of Zinc in Fertilizer
The zinc in fertilizer combines with other elements to form compounds with low solubility in water. Even when heated, the zinc in these compounds will not fully dissolve in water. Consequently, zinc fertilizer does not undergo chemical reactions during heating, unlike some other fertilizers.
5. Application Methods of Zinc Fertilizer
Zinc fertilizer is usually applied in solid form rather than being mixed directly with water. This is because the zinc compounds in fertilizer have low water solubility. To ensure effective absorption by plants, zinc fertilizer must be evenly dispersed in soil after mixing with water.
6. Storage and Transportation of Zinc Fertilizer
Since zinc fertilizer does not undergo chemical reactions during heating, special handling is unnecessary for storage or transportation. It can be stored in cool, dry conditions without additional precautions.
7. Safety of Zinc Fertilizer
Zinc is an essential microelement for humans and other organisms. Moderate zinc intake is critical for maintaining health. excessive zinc intake can lead to poisoning, causing symptoms such as nausea, vomiting, and diarrhea. dosage control is crucial when using zinc fertilizer to avoid overapplication.
the reason zinc fertilizer does not melt is determined by its inherent chemical properties and physical state. Additionally, its application methods contribute to its stability during heating. When using zinc fertilizer, it is important to control the dosage to prevent excessive use.
