Straights

With the Increase in popularity of variable rate spreaders and precision farming, the demand to apply straights to areas of land requiring specific dressings is increasing. Gleadell import and supply all forms of straights.

Triple Super Phosphate

Triple Super Phosphate is made by the action of Phosphoric Acid on raw Rock Phosphate [also called Appatite]. It typically contains 46% Phosphate, soluble in neutral ammonium citrate and water. Of this, typically 90% is soluble in water alone. Because the phosphate on TSP is never completely water-soluble, it cannot be used in the manufacture of clear-liquid fertilisers. Triple Super Phosphate for the European market comes from North Africa or from sometimes from Florida, trans-shipped at Rotterdam.

Murate of Potash

Muriate of Potash typically contains 60% Potash. Potash is important because it helps the plant to grow vegetative matter like straw and stalk and produce reproductive matter like seeds. It also protects itself against drought, Root crops like siliage, potatoes and sugar beet remove large amounts of potash in the roots, so large amounts of Muriate of Potash are often applied to these crops.

Mono Ammonium Phosphate

MAP typically contains 11% Nitrogen in the Ammonium form and 52% Phosphate. It is sometimes expressed as 11-52-0. MAP is made by the action of ammonia with phosphoric acid, the resulting salt is completely water-soluble. Because the water-solubility of MAP is very high it is used in both solid and clear-liquid fertilisers.

Di-ammonium Phosphate

DAP typically contains 18% Nitrogen in the Ammonium form and 46% Phosphate. It is sometimes expressed as 18-46-0. DAP is made by the action of ammonia with phosphoric acid, the resulting salt is completely water-soluble. Because the water-solubility of DAP is very high it is used in both solid and clear liquid fertilisers. It is often more expensive than MAP so it is not always imported into the UK in every season. MAP is much more commonly used.
