## Description

## Kierserite Granular Magnesium Sulphate - 15.1% Mg, 20% S

Kierserite is a premium quality, naturally occurring mineral that provides essential nutrients for plant growth. Comprised of magnesium sulphate monohydrate, it is mined from ancient marine deposits and is widely used as a fertilizer source for magnesium and sulphur in the agricultural industry.

This granular form of Kierserite is perfect for blending with other granular fertilizers, allowing you to create custom blends to suit your needs. It dissolves slowly with soil moisture, providing a steady supply of nutrients to your plants over time. Unlike other forms of magnesium sulphate, Kierserite will not leach quickly from the soil, making it a reliable and efficient choice for soil application to a wide range of horticultural and broad acre crops.

You can increase chlorophyll production by supplementing magnesium in your plants, boosting photosynthesis and overall plant health. Kierserite is especially ideal for crops grown in low-magnesium soils, helping to improve productivity and yield.

Please note that Kierserite is not suitable for fertigation or foliar application. Invest in the best for your plants and give them the nutrients they need to thrive with Kierserite Granular Magnesium Sulphate.
