Sulfate Iron (II) Hydroxide
Sulfate Iron (II) Hydroxide is a specialized iron supplement and soil amendment used primarily to correct iron deficiency in plants and improve soil conditions in alkaline or calcareous soils. This compound provides iron in a form that is more stable and less prone to oxidation than simple iron salts, ensuring better availability to plants. It is particularly effective in high-pH soils where iron becomes insoluble and unavailable. By supplying both iron and sulfur, it addresses chlorosis (yellowing of leaves) and promotes healthy chlorophyll synthesis, leading to improved plant vigor, greener foliage, and enhanced crop yields.

Product Details

1. Key Features
Stable Iron Source: The hydroxide form offers a slower, more controlled release of iron compared to highly soluble salts like ferrous sulfate, reducing the risk of rapid oxidation and precipitation in the soil.
Dual Nutrient Supply: Provides both iron (Fe) and sulfur (S), two essential nutrients that are often deficient in high-pH soils.
Soil pH Moderation: The sulfate component can help to slightly acidify the rhizosphere (root zone), which is crucial for improving iron availability in alkaline conditions.
Targeted Action: Specifically formulated to combat iron chlorosis, a common problem in crops grown on calcareous soils.

Reduced Phytotoxicity: Less likely to cause leaf burn compared to some other iron fertilizers when used as directed.

2. Primary Functions and Benefits

FunctionBenefit to PlantsAgronomic Advantage
Corrects Iron DeficiencyReverses interveinal chlorosis (yellowing between leaf veins) by supplying bioavailable iron.Restores photosynthetic capacity, leading to healthier, greener plants and preventing yield loss.
Enhances Chlorophyll SynthesisIron is a key catalyst in the production of chlorophyll.Improves the plant's ability to capture light energy, resulting in better growth and development.
Improves Soil ConditionsThe sulfate ions help to lower the pH in the immediate root zone.Makes iron and other micronutrients (like manganese and zinc) more available for plant uptake in alkaline soils.
Provides Essential SulfurSulfur is necessary for protein synthesis and enzyme activity.Supports overall plant metabolism and improves nitrogen use efficiency.

3. Target Crops and Application Scenarios
Iron-Efficient Crops: Soybeans, sorghum, corn, and many vegetables - These crops can utilize iron more effectively when it is supplied in a stable form like Sulfate Iron (II) Hydroxide.
High-pH Soils: Essential for crops grown in calcareous (limestone-rich) soils, where iron deficiency is most prevalent.
Sensitive Crops: Particularly beneficial for citrus, grapes, pecans, and ornamentals that are highly susceptible to iron chlorosis.
Application Timing: Best applied at the first sign of chlorosis or as a preventative measure during the early growth stages.
4.Application Guidelines (General)
Soil Application:
Broadcast: Apply evenly over the soil surface and incorporate through light tillage or irrigation.
Band Application: Place in bands near the plant root zone for more efficient uptake.
Rates: Vary depending on the severity of deficiency and soil conditions. Typical application rates range from 10 to 50 kg per hectare.
Fertigation: Can be applied through irrigation systems if the product is formulated for high solubility. Ensure compatibility with other fertilizers in the system.
Precautions:
Avoid over-application, as excess iron can interfere with the uptake of other nutrients like phosphorus and manganese.

Store in a cool, dry place to prevent oxidation and caking.


Note: Sulfate Iron (II) Hydroxide occupies a middle ground between inexpensive but unstable ferrous sulfate and highly effective but expensive chelated iron. It is a cost-effective solution for managing iron deficiency in situations where the soil pH is not extremely high or where the deficiency is not severe. For the most challenging high-pH soil conditions, chelated iron may be necessary for optimal results.
