Potassium Sulphate is colorless or white hexagonal or
Rhombic crystal or granular powder. The relative density is 2.662.
The inversion point is at 588° C, the melting point is at 1069° C
And the boiling point is at 1689° C. It is soluble in water(12g/100ml water at 25° C; 24.1g/100ml water at 100° C) and insoluble in alcohol, acetone and carbon bisulfide. It tastes bitter and salty.
Plastic woven bag inner with plastic bag in 25/40/50kg net.
Handling and Storage:
Store in ventilated and dry house with the package sealed away from moisture. Prevent the material from rain in case to be dissolved and lost during transportation
These exclusive combined properties of SOP ensure a better mineral nutrition, an improved photosynthesis and translocation of assimilates, an increased resistance to diseases, a better appearance and taste as well as an improved nutritional value of fruits and vegetables.
Monband SOP doesn't contain any nitrogen: It thus allows a better management of the nitrogen fertileation, especially for those crops which require very moderate n dressings (if at all )towards the end of their growing cycle, in order to achieve the best quality of the crop.
When application at 20º C, it normally takes only a few minutes for nutriaqua sop to dissolve.
