Magnesium Fertilizers

 Magnesium sulphate heptahydrate in white crystal form is a high-purity, fully water-soluble fertilizer rich in magnesium and sulfur. It features bright pure white appearance, uniform crystal particles, no discoloration or caking. With excellent solubility and zero residue after dissolution, it will never block drip irrigation pipes and spray nozzles. As a premium magnesium & sulfur supplement, it effectively solves common crop problems including magnesium-deficient yellow leaves, premature senescence, weak photosynthesis, small fruits and poor coloration. Widely applied in agriculture, feed industry, textile printing, building materials, daily chemicals and other fields. Boasting stable quality, sufficient effective content, strong anti-weathering performance and cost-effectiveness, it is a mainstream product favored by global markets.

Magnesium sulphate heptahydrate brown granular is a high-purity medium and trace element fertilizer. Made by advanced granulation technology, the product features uniform particles, moderate hardness and excellent anti-caking performance. It dissolves fast and completely without residue, suitable for drip irrigation, sprinkler irrigation, broadcasting and flushing fertilization. It efficiently supplies magnesium and sulfur nutrients, promotes chlorophyll formation and photosynthesis, and improves crop growth, yield and quality. With good fluidity and storage stability, magnesium sulphate heptahydrate brown granular is highly suitable for long-distance ocean transportation. It is widely used on fruits, vegetables, field crops and cash crops, and is a popular high-quality magnesium fertilizer in global markets.

Magnesium sulphate heptahydrate (MgSO4·7H2O) is manufactured using a professional granulation process combined with a unique violet coloring technology, offering both high nutritional efficiency and ease of use. The product contains over 9.8% water-soluble magnesium and over 12% sulfur. The synergistic effect of these two nutrients—magnesium, as a core component of chlorophyll, directly drives photosynthesis, while sulfur participates in protein synthesis—doublely contributes to improving crop quality and yield. It effectively prevents problems such as leaf yellowing and premature aging due to nutrient deficiencies, and enhances drought resistance, disease resistance, and stress resistance.

Magnesium sulphate granulars are a type of fertilizer containing two medium-nutrient elements, sulfur and magnesium. Their primary ingredient is typically magnesium sulfate monohydrate (MgSO4·H2O). They promote plant photosynthesis, enhance disease resistance, promote root growth, increase chlorophyll content, boost crop yields, and improve soil properties.

Magnesium Sulphate Violet Granular, its granular form allows for even spreading or hole application, dissolves and absorbs quickly, and can quickly alleviate problems such as yellowing leaves and weak photosynthesis caused by magnesium deficiency in crops. It is especially suitable for fruits, vegetables, flowers, field crops and other categories that require high amounts of magnesium, helping to increase crop yield and quality, while supplementing sulfur to promote balanced nutrient absorption.

Magnesium Sulphate Green Granular(kieserite granular) are a highly effective, environmentally friendly, multi-element fertilizer. Their primary ingredient is magnesium sulphate, which contains the two secondary nutrients sulfur and magnesium. Some products also contain trace elements such as zinc, boron, and iron.

Magnesium sulphate heptahydrate blue granular are a high-purity, multifunctional chemical product with a primary magnesium sulfate content of 99% or higher. They appear as uniform blue spherical or quasi-spherical particles with customizable particle sizes. Their key features include rapid dissolution without residue, rapid release of active ingredients such as magnesium (approximately 9.5%) and sulfur (approximately 12.0%), and the absence of chlorine.

Magnesium sulphate heptahydrate yellow granulars for agricultural use are a specialized medium-element fertilizer made from high-purity magnesium sulfate heptahydrate through an extrusion granulation process. Their yellow appearance stems from the raw material's characteristics or the coloring process, and does not affect their core efficacy. The granular form effectively solves the problems of traditional powders prone to moisture absorption, agglomeration, and dust generation. Suitable for various fertilization methods, including broadcasting, furrow application, and foliar spraying, they facilitate precise manual or mechanical application.

2-4mm magnesium sulphate crystals are generally magnesium sulphate heptahydrate, with a molecular formula of MgSO4·7H2O and a molecular weight of 246.47. They appear as columnar crystals with a main content of ≥99.5%, ≥48.59% magnesium sulphate, ≥9.8% magnesium, and ≥16.2% magnesium oxide. They are readily soluble in water and slightly soluble in ethanol and glycerin. They are primarily used in the pharmaceutical, food, agricultural, and industrial sectors. In medicine, they can be used to prepare protective ointments and laxatives, and in agriculture, they serve as an excellent magnesium fertilizer.

Magnesium sulphate granular can act as a fertilizer to supplement crops with key magnesium and sulfur elements, help chlorophyll synthesis, improve photosynthesis efficiency, accelerate protein synthesis, and allow crops to thrive, with both yield and quality improved. At the same time, it has a soil improvement effect. If used in combination with other fertilizers such as nitrogen, phosphorus, and potassium, it can also improve fertilizer utilization and reduce nutrient loss, saving money and being efficient.

Magnesium sulphate granular can be used as fertilizer in agriculture to supplement magnesium and sulfur elements for plants, promote photosynthesis and protein synthesis, and increase crop yield and quality; they can also improve the soil, regulate pH, improve soil structure, and facilitate root growth; when used in combination with other fertilizers, they can improve fertilizer efficiency and reduce nutrient loss and waste.

Magnesium sulphate heptahydrate 2 - 4mm crystals, with the chemical formula MgSO4·7H2O are white or colorless needle-shaped or oblique columnar crystals with a glassy luster, odorless, cool and slightly bitter taste, and easily soluble in water. It loses crystal water at different temperatures and has a certain stability. It is used in industry for leather making, papermaking, etc.; in agriculture, it is a magnesium fertilizer that can improve soil; in medicine, it is used as Epsom salt, etc.; it is also used in mineral water, building materials and other fields.
