Magnesium Fertilizers

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.

Magnesium sulphate heptahydrate compected granular, chemical formula MgSO4·7H2O. It has a regular shape, good fluidity, high hardness, is easily soluble in water, and has stable chemical properties. It is a high-quality fertilizer in agriculture and can enhance crop photosynthesis; it is used in printing and dyeing, building materials and other fields in industry. It is mostly packaged in 25kg or 50kg woven bags. It should be stored in moisture-proof and acid-free bags.

Magnesium sulphate heptahydrate(MgSO4·7H2O), also known as sulfur bitter, bitter salt, laxative salt or laxative salt, is a white or colorless needle shaped or oblique columnar crystal, odorless and slightly bitter. It gradually loses its crystalline water and becomes anhydrous magnesium sulfate when heated. It is easily soluble in water, slightly soluble in ethanol and glycerol, soluble in its own crystal water at 67.5 ℃, and loses all crystal water at about 200 ℃
