SEA-90 minerals and trace elements can be used alone and/or mixed with most water soluble fertilizers. It can be added to any foliar spraying program as a mineral and trace element source. SEA-90 is a natural surfactant. By adding it to your foliar spray, it will assist in spreading and absorption of the minerals and trace elements. To increase effectiveness, add fish emulsion as a nitrogen source, humate (per manufacturer recommendations), and one half pound cane sugar per acre. SEA-90 might contain small amounts of sediment. Therefore, prior to adding dissolved SEA-90 to spray tank, we suggest mixing desired amount with water to allow sediment to settle and filter if necessary.
