Introduction of kieserite fertilizer for oil palm and usage method:
Magnesium deficiency is also quite common on palm plants, especially Canary date palms.
With potassium deficiency, symptoms first appear on older leaves and then spread throughout
the canopy. Typical symptoms are a distinct pale yellow band along the leaf margins, but the
center of the leaf remains green (Fig. 6). In severe cases of magnesium deficiency, necrosis
of the pinnae tips occurs less frequently, but when it does occur, it can lead to the death of the palm plant.
Dealing with a magnesium deficiency takes a considerable amount of time, so it is best
to take preventive measures for magnesium deficiency. Like potassium deficiency, magnesium
deficiency manifests as leaves that do not recover and must be replaced by healthy new
leaves. In acidic soils, dolomite and magnesia are excellent sources of slow-release magnesium,
but for neutral to alkaline soils, more water-soluble magnesite (a slightly soluble form of MgSO4)
or other more suitable Thin film magnesium sulfate. Apply 2 to 4 lbs (0.9 to 1.8 kg) per plant,
4 times a year, with an equal dose of K2SO4 to prevent potassium/magnesium imbalance。
Features of kieserite fertilizer for oil palm powder products: low content of chloride, heavy metals,
and free acid, free of chemical organic matter, high water solubility, no caking, free flowing and
weak alkaline.
The production principle of kieserite fertilizer for oil palm is that concentrated sulfuric acid reacts
directly with lightly burned powder (magnesia powder) or crushed magnesite raw ore to obtain
fertilizer grade magnesium sulfate monohydrate, which is reacted and solidified, and then crushed
or granulated to synthesize monohydrate magnesium sulfate also can called kieserite fertilizer, it is
yellowish or grey powder. The total mgo and water mgo content is the important element, and
it is partially soluble in water, completely soluble in hydrochloric acid.
