Magnesium Sulphate Fertilizer for Agriculture & Fertigation

Ⅰ.Application Overview

Product Overview产品概述

Magnesium is a key element in chlorophyll formation and photosynthesis. For high-value crops such as citrus, tomatoes, grapes, potatoes, and oilseed crops, magnesium deficiency can directly cause interveinal chlorosis, yellow leaves, poor fruit set, and yield reduction.

CNMGO International Trading specializes in magnesium sulphate and magnesium oxide products, supported by stable magnesite resources and mature production capacity. We supply high-purity Magnesium Sulphate Heptahydrate, Monohydrate, and agricultural-grade magnesium oxide for global fertilizer and agricultural markets.
