But defect is low nitrogen, but ammonium sulphate also have sulfur which is extremely advantageous to the crops. Storage: Kept in dry and ventilating place, avoid moisture, water, rain and fire. Avoid shipment with acid, alkali class, edible orange mix of chemicals.ContactSales LisaMobile +8615554397297Fax 00865434268950email sales003ATspringchemicalDOTcomWebsite www.springchemcal.comPLS ConTACT ME!
