Agricultural Magnesium Sulfate

AOLANSU Agricultural Magnesium Sulfate is a specialized agricultural magnesium fertilizer, primarily available in two forms: Magnesium Sulfate Heptahydrate (MgSO₄·7H₂O) and Magnesium Sulfate Monohydrate (MgSO₄·H₂O). Among these, magnesium sulfate heptahydrate is the most widely utilized in agricultural production due to its high magnesium content and excellent water solubility.

Agricultural Magnesium Sulfate presents as a white crystalline solid with no discernible odor. Throughout the entire production process, strict controls are maintained regarding impurities and heavy metals—such as lead, arsenic, and cadmium—ensuring that the product causes no contamination to the soil, crops, or the surrounding ecological environment. It dissolves rapidly, allowing nutrients to be quickly absorbed by crops with virtually no nutrient waste.

Core Benefits and Functions

1. Efficient Magnesium Supplementation for Crops

Magnesium is a core constituent of plant chlorophyll and an indispensable key element for photosynthesis. With an MgO content of ≥25%, AOLANSU Agricultural Magnesium Sulfate rapidly replenishes the magnesium required by crops, effectively resolving issues associated with magnesium deficiency—such as leaf yellowing, stunted growth, and reductions in both yield and quality. Furthermore, it promotes the synthesis of chlorophyll and biological enzymes, boosts photosynthetic efficiency, and facilitates nutrient accumulation within the crops.

2. Soil Improvement and Fertility Enhancement

Agricultural Magnesium Sulfate is compatible with all soil types, making it particularly beneficial for magnesium-deficient plots, including acidic soils, sandy soils, and saline-alkaline soils. It helps regulate soil pH levels, optimizes soil aggregate structure, enhances the soil's water-retention and nutrient-retention capacities, and alleviates soil compaction. Through long-term application, it sustainably improves soil fertility, creating an optimal growth environment for crops and enabling the achievement of stable, high-yield harvests.

3. Wide Range of Applicable Crops

Suitable for the large-scale cultivation of a diverse array of crops:

- Grain Crops: Rice, Wheat, Corn

- Cash Crops: Cotton, Oil Crops, Melons, Fruits, and Vegetables

- Horticultural Crops: Various Fruits, Flowers, and Landscaping Nursery Stock

4. Stable and Reliable Product Performance

AOLANSU Agricultural Magnesium Sulfate boasts a purity level of ≥98.5% with extremely low impurity content. All heavy metal indicators meet agricultural safety standards, ensuring it can be used with complete confidence in agricultural production. The product is easy to store and transport; when stored in compliance with guidelines, it resists caking. It supports various application methods—including basal fertilization, top dressing, drip irrigation, and spray irrigation—flexibly adapting to the specific requirements of different cultivation models.

Real-World Application Case Study

Case: Quality Improvement and Yield Enhancement in a Florida Citrus Orchard (USA)

At a 500-mu (approx. 33-hectare) citrus plantation in Florida, USA, severe soil magnesium deficiency led to widespread leaf yellowing, declining fruit quality, and an increased incidence of malformed fruit.

The growers at the plantation selected AOLANSU Agricultural Magnesium Sulfate. During the fruit expansion stage, they prepared a 1%–2% aqueous solution for foliar spraying. The solution was applied once every two weeks, with continuous application spanning one month.

Results: Within 10 days, symptoms of leaf yellowing visibly subsided, and photosynthetic efficiency increased by 28%. Average fruit weight increased by 35%, while the incidence of blossom-end rot dropped by 90%. Overall, the total yield of the orchard increased by 22%. Currently, the plantation has designated AOLANSU Agricultural Magnesium Sulfate as a staple, year-round agricultural supply purchase, recognizing its consistent quality and high cost-effectiveness.

FAQ

Q1:  What are the advantages of AOLANSU Agricultural Magnesium Sulfate compared to ordinary magnesium fertilizers?

A1: This product boasts a purity level exceeding 98.5% and an effective Magnesium Oxide (MgO) content of ≥25%. Its water solubility and nutrient utilization efficiency are far superior to those of ordinary magnesium fertilizers. Free from excessive heavy metals and harmful additives, it offers safer application, minimizes nutrient waste, effectively reduces cultivation costs, and simultaneously protects the ecological environment of farmland.

Q2: What is the correct application method for AOLANSU Agricultural Magnesium Sulfate?

A2: Application methods can be flexibly adjusted based on crop type and growth stage:

- Base Fertilizer: Apply during land preparation prior to sowing; broadcast 50–60 kg per mu (approx. 667 sq. meters), mixing it thoroughly with the soil.

- Top Dressing: Apply as a supplementary fertilizer during the crop's growth period at a rate of 10–15 kg per mu.

- Foliar Spraying: Prepare a 1%–2% aqueous solution and spray during the early morning or late evening. For best results, apply 2–3 times consecutively with an interval of 10–15 days between applications.

Q3: Is this product suitable for use in organic farming?

A3: Yes, it is. This product is non-toxic, non-polluting, and free of synthetic additives; it complies with the standards for organic fertilizers and can be safely applied in organic farming operations. It serves to replenish magnesium and improve soil quality without causing residual contamination to the ecological environment or agricultural produce.
